• Best embedded/customer auth: PingOne

If you want, I can turn this into a top 3 shortlist for your exact SaaS stack (e.g., Google Workspace, Salesforce, Slack, custom app, B2B customer login).

For admin accounts, the best MFA options are usually phishing-resistant methods, especially hardware security keys and passkeys.

Best choices

1. YubiKey 5 Series (Yubico)
   • Best overall for admins
   • Supports FIDO2/WebAuthn, PIV, OTP
   • Great for Microsoft, Google, Okta, AWS, GitHub, and more
2. Google Titan Security Key
   • Strong, simple hardware key
   • Good if your environment is mostly Google/Workspace-based
3. Feitian ePass FIDO2

Best MFA platforms for admin access

• Microsoft Entra ID (Azure AD) + Conditional Access

Best for Microsoft-heavy orgs; combine with FIDO2 keys or passkeys

• Okta Adaptive MFA

Strong enterprise MFA and policy control

• Cisco Duo

Very good admin MFA, easy deployment, strong device trust options

• 1Password Business / Bitwarden Enterprise

Useful for password + passkey management, but not a full replacement for admin-grade MFA policies

Best practice recommendation

For admin accounts, use:

• FIDO2 security keys as primary MFA
• 2 keys per admin (one primary, one backup)
• No SMS or app push for privileged accounts if you can avoid it
• Pair with conditional access / device trust

My short recommendation

If you want the safest, most practical setup: YubiKey 5 NFC + Microsoft Entra ID or Okta + conditional access.

If you tell me your stack (Microsoft, Google, AWS, Okta, etc.), I can recommend the best exact setup.

For admin accounts, the best MFA is usually phishing-resistant MFA: FIDO2/WebAuthn passkeys or hardware security keys. NIST says phishing-resistant authenticators are the standard to aim for, and that OTP/manual-code methods are not phishing-resistant. (pages.nist.gov)

Best choices by stack

• Microsoft Entra ID: FIDO2 security keys or passkeys/Windows Hello for Business for admins and highly regulated users. Microsoft explicitly recommends phishing-resistant methods for the strongest sign-in experience. (learn.microsoft.com)
• Okta: WebAuthn/FIDO2 security keys; Okta supports YubiKeys as OTP, WebAuthn, or both, and admin MFA can be enforced on the Admin Console. (help.okta.com)
• Cisco Duo: YubiKeys/WebAuthn security keys for Duo admin logins and end users. Duo supports WebAuthn security keys for the Admin Panel and passwordless flows. (duo.com)
• AWS: Passkeys/security keys for root and IAM users; AWS recommends them over TOTP and allows multiple MFA devices for redundancy. (docs.aws.amazon.com)

My practical recommendation

1. Primary MFA: 2x FIDO2 security keys per admin (for example, YubiKey 5 Series or YubiKey 5 FIPS if you need compliance). (yubico.com)
2. Policy: require phishing-resistant MFA for all privileged roles. (learn.microsoft.com)
3. Backup: a second key stored separately; use TOTP only as a fallback, not the main method. (docs.aws.amazon.com)

Short answer: if you want the safest admin MFA setup today, choose FIDO2 security keys + enforced phishing-resistant policies in your identity provider. (learn.microsoft.com)

If you want, I can give you a best-by-budget list (small business vs enterprise) or a specific setup for Microsoft/Google/AWS/Okta/Duo.

For customer portals, the best MFA options are usually customer identity / CIAM platforms with built-in MFA, not employee-only tools.

• AWS Cognito: decent if you’re already on AWS, but less polished than Auth0/Okta
• Duo: strong MFA product, but better known for workforce than full customer portal identity
• FusionAuth: good self-hosted/on-prem option with flexible MFA

Best MFA methods for customer portals

• Passkeys: best user experience and security
• Authenticator app (TOTP): most common and reliable
• WebAuthn/FIDO2 security keys: strongest security
• SMS: only as backup, not primary
• Email OTP: convenient, but weaker

My short recommendation

• Best overall: Auth0
• Best enterprise: Okta Customer Identity Cloud
• Best Microsoft shop: Entra External ID
• Best on-prem/self-hosted: FusionAuth

If you want, I can also rank these by price, ease of setup, or security strength.

For customer portals, the best MFA solutions are usually CIAM-first platforms with passkeys/WebAuthn, adaptive risk checks, and email/SMS/TOTP fallbacks. My short list:

1. Okta Customer Identity Cloud (Auth0) — best all-around for flexible customer-facing MFA, with WebAuthn/passkeys and multiple factor options. (okta.com)
2. Microsoft Entra External ID — best if you’re already in Microsoft land; external tenants support MFA and passkeys/FIDO2, with email OTP and SMS options for customers. (learn.microsoft.com)
3. PingOne for Customers / PingOne MFA — strong choice for adaptive customer authentication and embedding MFA into web/mobile portals. (pingidentity.com)
4. Amazon Cognito — best lower-cost, AWS-native option; it now supports email MFA, SMS, TOTP, and passwordless/passkeys. (aws.amazon.com)
5. Cisco Duo — best as a strong MFA layer when you want very reliable WebAuthn/security-key and push-based auth, though it’s more commonly positioned as an MFA product than a full CIAM suite. (duo.com)

If I had to pick:

• Best overall: Okta Customer Identity Cloud / Auth0. (okta.com)
• Best Microsoft-centric: Microsoft Entra External ID. (learn.microsoft.com)
• Best AWS-native: Amazon Cognito. (aws.amazon.com)

A good customer-portal MFA setup today usually prioritizes passkeys (phishing-resistant) first, then TOTP, then email/SMS recovery or fallback. That’s an inference based on the vendors’ current support for passkeys/WebAuthn and other factors. (auth0.com)

If you want, I can narrow this to:

• best for SaaS portals
• best for consumer apps
• best budget option
• best for HIPAA/PCI-heavy environments

The best MFA solutions for passwordless login today are mostly FIDO2 / passkey-based products.

• Uses face/fingerprint/PIN for phishing-resistant login

What I’d choose

• Enterprise Microsoft stack: Microsoft Entra ID + YubiKey 5C NFC
• General enterprise: Okta + YubiKey
• Simple, strong MFA: Duo + YubiKey
• Google-centric org: Google Workspace + Titan Security Key
• Personal use: Apple Passkeys or 1Password Passkeys

If you want, I can also give you the top 3 picks by budget, company size, or compliance needs.

If you mean passwordless + phishing-resistant MFA, the best options today are usually passkeys / FIDO2 rather than SMS or email OTP. Passkeys are FIDO credentials that use device biometrics, PIN, or security keys, and FIDO notes they can act as MFA when user verification is required. (fidoalliance.org)

My shortlist:

1. Microsoft Entra ID + passkeys (FIDO2) + Microsoft Authenticator — best if you’re already in Microsoft 365 / Windows. Microsoft supports device-bound and synced passkeys, plus security keys and Authenticator sign-in. (learn.microsoft.com)
2. Cisco Duo Passwordless — strong choice for enterprises that want an easy rollout across SSO apps; Duo supports passkeys, platform authenticators, security keys, and Duo Push in a passwordless flow. (duo.com)
3. Okta Identity Engine / FastPass — good for mixed environments and SSO, with passwordless or password-optional sign-in and app policies for passwordless MFA. (help.okta.com)
4. YubiKey / FIDO2 security keys — best for highest assurance and regulated environments; hardware keys are phishing-resistant and work with major platforms. (yubico.com)
5. 1Password or Bitwarden passkeys — best if you want a passkey manager for users or teams; both support storing and using passkeys, and can reduce reliance on passwords. (1password.com)

Quick rule of thumb:

• Best overall enterprise: Microsoft Entra ID
• Best security-first rollout: Duo or YubiKey
• Best developer/customer identity: Auth0 or Okta
• Best passkey vault: 1Password or Bitwarden

If you want, I can narrow this to enterprise, small business, or consumer app use cases.

Quick pick:

• Best overall for mobile apps: Auth0
• Best for AWS: Cognito
• Best for Firebase-first apps: Firebase Auth
• Best for enterprise push MFA: Duo or Okta
• Best for Microsoft shops: Entra + Authenticator

If you want, I can also give you a ranked shortlist for your app type (consumer, B2B, fintech, healthcare, etc.).

For APIs, the “best MFA” usually means strong identity + step-up auth for humans, and machine-to-machine controls for the API itself. APIs typically aren’t protected by classic OTP MFA alone.

Best options by use case

1) Human admins / developers accessing API dashboards

• Okta Workforce Identity + FastPass / WebAuthn (FIDO2)
• Microsoft Entra ID + Conditional Access / MFA
• Cisco Duo
• PingOne
• OneLogin

Best pick: Okta or Microsoft Entra ID for enterprise, Duo for simpler rollout.

2) Public APIs with external clients Use OAuth 2.1 / OpenID Connect with:

• Authorization Code + PKCE for user-facing apps
• Client Credentials for server-to-server
• Short-lived access tokens
• Step-up MFA when users perform sensitive actions

Products:

• Auth0
• Okta Customer Identity
• Azure AD B2C / Entra External ID
• PingOne for Customers
• FusionAuth (good self-hosted option)

Best pick: Auth0 for fastest implementation.

3) Service-to-service / machine APIs MFA is not the right control here. Use:

• mTLS
• OAuth 2.0 client credentials
• Signed JWTs
• API gateways

Products:

• Kong Gateway
• Apigee
• AWS API Gateway + IAM
• Azure API Management
• NGINX Plus

Best pick: Kong Gateway or Apigee.

Strongest overall combo

• Okta or Entra ID for workforce MFA
• Auth0 / PingOne / FusionAuth for customer auth
• Kong / Apigee + mTLS + OAuth2 for API enforcement

If you want the single best practical setup

Auth0 + FIDO2/WebAuthn MFA + short-lived JWTs + mTLS for service traffic.

If you tell me your environment (AWS/Azure/GCP, internal vs public API, B2B vs consumer), I can recommend the best exact stack.

For APIs, the best setup is usually not just MFA—it’s phishing-resistant user MFA + proof-of-possession for tokens. In practice, the strongest options are:

1. Microsoft Entra ID + Conditional Access + passkeys/FIDO2

Best if you’re already in Microsoft. Passkeys are phishing-resistant, can act as MFA, and Conditional Access can require them for sensitive resources. (learn.microsoft.com)

1. Okta / Auth0 with WebAuthn (passkeys) + step-up auth

Best for customer-facing APIs and app builders. Auth0 supports MFA, adaptive MFA, and step-up authentication for sensitive API scopes; Okta supports FIDO2/WebAuthn passkeys and lets admins restrict synced passkeys. (auth0.com)

1. AWS Cognito MFA + API Gateway mTLS

Best if your stack is AWS-native. Cognito supports MFA for user pools, and API Gateway supports mutual TLS for stronger API protection. (docs.aws.amazon.com)

1. OAuth 2.0 mTLS or DPoP for API tokens

Best for protecting bearer tokens from replay. RFC 8705 defines OAuth mTLS, and RFC 9449 defines DPoP. These are especially important for machine-to-machine APIs where classic MFA doesn’t fit. (ietf.org)

My practical ranking:

• Best overall: passkeys/FIDO2 + conditional access. (learn.microsoft.com)
• Best for customer identity / app APIs: Auth0 or Okta with step-up MFA. (auth0.com)
• Best for service-to-service APIs: OAuth mTLS or DPoP. (ietf.org)

Avoid SMS MFA if you can; OWASP calls it vulnerable to SIM swapping and phishing. (cheatsheetseries.owasp.org)

If you want, I can turn this into a vendor shortlist by budget (enterprise, mid-market, startup) or a reference architecture for your API stack.

For remote access security, the best MFA options are usually the ones that work well with VPNs, SSO, and device trust. Top picks:

• Okta Adaptive MFA — strong for enterprise SSO, VPN, and conditional access; very mature admin controls.
• Microsoft Entra ID (Azure MFA) — best if you use Microsoft 365/Windows; integrates tightly with Conditional Access and remote access apps.
• Cisco Duo — excellent for VPN and zero-trust access; very easy to deploy and widely supported.
• PingID / PingOne MFA — good for large enterprises needing flexible policies and federated access.
• RSA SecurID — classic enterprise MFA, still strong in regulated environments.
• Delinea Authenticator — good for privileged access and admin remote login.
• Yubico YubiKey — best hardware-based option for phishing-resistant MFA, especially for high-security users.

Best overall recommendations:

• Best enterprise all-around: Cisco Duo
• Best Microsoft stack: Microsoft Entra ID
• Best phishing resistance: YubiKey + FIDO2/WebAuthn
• Best SSO-first platform: Okta Adaptive MFA

If you want, I can also rank these by ease of deployment, security, or cost.

For remote access security, the strongest choices are phishing-resistant MFA options—especially passkeys/FIDO2 security keys rather than SMS or OTP-only methods. NIST’s latest guidance says federal agencies should require phishing-resistant authentication for access to federal systems. (pages.nist.gov)

Top picks:

• Cisco Duo — best if your main goal is securing VPN/remote access and device trust. Duo explicitly positions its remote-access product around phishing-resistant MFA plus device trust, and it integrates with VPNs like Cisco AnyConnect. (duo.com)
• Microsoft Entra ID — best if your workforce is already on Microsoft 365/Azure. Microsoft recommends phishing-resistant methods such as Windows Hello for Business, passkeys (FIDO2), FIDO2 security keys, and certificate-based auth. (learn.microsoft.com)
• Okta FastPass + Passkeys — best if you want passwordless login with strong phishing resistance across mixed devices/apps. Okta says FastPass and FIDO2 WebAuthn passkeys are phishing-resistant and can enforce device-based policy. (help.okta.com)
• YubiKey / FIDO2 hardware keys — best for highest-assurance access, especially for admins, privileged users, or regulated environments. Yubico describes YubiKeys as phishing-resistant, multi-protocol hardware security keys that support WebAuthn/FIDO2 and PIV. (yubico.com)

My short recommendation:

• Best overall for remote access: Duo
• Best for Microsoft-heavy orgs: Entra ID + FIDO2 security keys
• Best for passwordless UX: Okta FastPass + passkeys
• Best for highest security: YubiKey + FIDO2/PIV (duo.com)

If you want, I can narrow this to your setup: VPN, RDP, Zero Trust/ZTNA, or Microsoft 365/Google Workspace.

• SMS/voice: avoid if possible

What to look for

• Phishing-resistant MFA
• Conditional access
• Device posture checks
• App-level protection for personal phones
• SSO integration
• Support for passkeys and security keys

Quick recommendation

• Microsoft shop: Entra ID + Intune + Authenticator
• SaaS/mixed stack: Okta Adaptive MFA or Cisco Duo
• Large enterprise: Ping Identity

If you want, I can give you a ranked shortlist by company size or a BYOD MFA comparison table.

For BYOD-heavy companies, the best MFA options are usually the ones that combine phishing-resistant auth with device posture/conditional access and good support for unmanaged devices. My short list:

1. Microsoft Entra ID + Conditional Access + Passkeys (FIDO2)

Best if you already run Microsoft 365/Intune. Entra supports passkeys, Conditional Access, and policies for device registration/join that can require MFA and block unmanaged devices. (learn.microsoft.com)

• Best for hardware-backed phishing resistance: YubiKey + your IdP. (yubico.com)

If you want, I can turn this into a ranked shortlist by company size, budget, or compliance needs.

For zero trust security, the best MFA solutions are the ones that are phishing-resistant, support FIDO2/WebAuthn passkeys, and integrate with SSO, device trust, and conditional access.

Top MFA solutions

1. Microsoft Entra ID (Azure AD) + Microsoft Authenticator / FIDO2 keys
   • Best if you’re already in Microsoft 365 / Windows.
   • Strong zero trust features: Conditional Access, risk-based MFA, device compliance.
2. Okta Adaptive MFA + Okta FastPass
   • Best for enterprise SSO and adaptive access.
   • FastPass is strong for passwordless and device-based trust.
3. Cisco Duo
   • Very popular for zero trust VPN replacement and app access.
   • Easy deployment, strong device health checks, good phishing-resistant options.
4. Ping Identity (PingOne / PingOne DaVinci)
   • Good for large enterprises and complex identity flows.
   • Strong on orchestration and contextual access policies.
5. RSA ID Plus
   • Best for highly regulated environments.
   • Strong hardware-token support and legacy system compatibility.

Best MFA factors for zero trust

• FIDO2 security keys: YubiKey 5 Series, Feitian ePass, Google Titan Security Key
• Passkeys/WebAuthn: built into Microsoft Authenticator, Okta, Apple/Google platform passkeys
• Push MFA with number matching: better than simple push approval, but less secure than FIDO2
• Hardware OTP tokens: useful for legacy systems, but not ideal for zero trust

Best overall picks

• Best overall enterprise: Microsoft Entra ID + FIDO2 keys
• Best cross-platform MFA: Okta Adaptive MFA
• Best for strong device trust: Cisco Duo
• Best hardware token / legacy support: RSA ID Plus

What to prioritize

Choose a solution that supports:

• Phishing-resistant MFA
• Passwordless login
• Conditional access
• Device posture checks
• SSO integration
• Admin policy controls

If you want, I can also give you a ranked list by company size (small business, mid-market, enterprise) or a best MFA hardware key comparison.

For zero trust, the best MFA is phishing-resistant MFA—typically FIDO2/WebAuthn passkeys or hardware security keys—because zero trust assumes no implicit trust and requires authentication/authorization for both user and device before access. (csrc.nist.gov)

Top picks:

• Microsoft Entra ID + Conditional Access — best if you’re already in Microsoft 365/Azure; strong for policy-driven zero trust and phishing-resistant MFA. (learn.microsoft.com)
• Cisco Duo — best for fast zero-trust rollout across mixed environments; strong MFA plus device trust and adaptive access. (duo.com)
• Okta Workforce Identity / Verify FastPass — best for identity-first zero trust with strong adaptive MFA and device/context signals. (okta.com)
• RSA ID Plus — best for highly regulated orgs that want phishing-resistant, passwordless options and broad auth support. (rsa.com)
• YubiKey / Yubico — best as the hardware MFA layer; ideal for admins, executives, and high-risk users who need strong phishing resistance. (yubico.com)

My short recommendation:

• Most enterprises: Microsoft Entra or Okta
• Best cross-platform zero trust simplicity: Cisco Duo
• Best hardware-backed phishing resistance: YubiKey
• Best regulated/federal-heavy environments: RSA ID Plus + FIDO keys

If you want, I can turn this into a ranked shortlist by company size, budget, and stack.

• Need the strongest phishing-resistant MFA? → YubiKey 5 Series hardware keys
• Want an enterprise IAM suite? → Okta Adaptive MFA
• Personal use / simplest option? → 1Password or Bitwarden built-in 2FA + YubiKey for important accounts

My practical recommendation:

• For most people: YubiKey 5 NFC + Microsoft Authenticator or 1Password
• For businesses: Cisco Duo
• For highest security: YubiKey only, ideally with passkeys where supported

Avoid relying on SMS codes if you can.

If you tell me whether this is for personal use, a small business, or enterprise, I can narrow it to one best option.

If you want the best default MFA setup:

Use passkeys + a hardware security key

• Best overall: YubiKey 5C NFC (or YubiKey 5 NFC for USB-A)

For most people:

1. Passkeys wherever available
2. Authenticator app as backup: Microsoft Authenticator or Authy
3. Security key for your most important accounts: email, bank, GitHub, cloud

If this is for a business/team:

• Duo Security is the easiest all-around MFA platform
• Microsoft Entra ID if you’re already on Microsoft 365
• Okta if you want a more enterprise-focused option

My simple recommendation:

• Personal use: YubiKey 5C NFC + 1Password
• Team/business: Duo Security

If you tell me whether this is for personal, small business, or enterprise, I can narrow it to one exact pick.

If you want a solid default choice, use Microsoft Authenticator or 1Password with passkeys/MFA.

Best overall picks

• For most people: 1Password

Great if you want one app for passwords + 2FA codes + passkeys.

• Best free option: Microsoft Authenticator

Simple, reliable, and supports passkeys and push approval.
