Passwordless Authentication Factors

With Passwordless connections, users can log in without a password. Instead, they can use a variety of other authentication factors. Auth0 Passwordless connections support the following authentication factors:

Factor Description
Email The user is asked to enter their email address, to which Auth0 sends a one-time-use code. The user enters the code into your application.
Magic Link The user is asked to enter their email address, to which Auth0 sends an email with a link in it. The user clicks the link and is directly logged in to your application.
SMS The user is asked to enter their phone number, to which Auth0 sends a one-time-use code. By default, Auth0 uses Twilio to send the code, but if you have a custom SMS gateway, you can modify your connection to use that instead.
