Passwordless Connection Limitations

Passwordless Connection Limitations

The type of authentication you want to use depends on which version of Universal Login you configured with your application. If you are using the New Universal Login experience, you can set up passwordless authentication using WebAuthN with Device Biometrics. The New Universal Login experience does not support SMS or email.

If you are using the Classic Universal Login experience, you can set up email or SMS passwordless authentication using the following methods:

  1. Classic Universal Login + Lock

  2. Classic Universal Login + custom UI + Auth0.js

To learn more about these implementations, read Configure Email or SMS for Passwordless Authentication.

Errors

If the passwordless option is not showing up on Universal Login or not functioning as expected, you may be using New Universal Login with email or SMS, which is unsupported. Try configuring device biometrics.

If you are using an embedded login, we recommend using custom domains. To learn more, rad

Considerations

  • You cannot create passwordless users from the Auth0 Dashboard. Create them directly from the Management API.

  • Refresh tokens cannot be retrieved when using a passwordless magic link via email, only an OTP.
