Backend authentication overview

Build frictionless and secure authentication experiences for your users across all their devices and channels.


Backend Authentication APIs allow you to implement authentication using a backend-to-backend integration. If you're looking for social login or a hosted WebAuthn experience, click here.

Strong biometric MFA

Based on the FIDO2 WebAuthn standard, biometric login is secure, consistent, and convenient for your customers.

One-time login

Login users using a one-time code sent to their phone or email, or magic link sent to their email. This passwordless option allows users to login to a device that doesn't support WebAuthn biometrics, or that doesn't belong to them.

Time-based passcodes

Login users using time-based one-time passcodes (TOTP) generated by authenticator apps like Google Authenticator or Twilio Authy.

Password login

Password login allows you to authenticate users with a username and password, so you can smoothly migrate your customers from passwords to a passwordless solution.
