Problem statement
During the login page configuration, how to allow users to choose between SMS and Email for Passwordless login?
Solution
Out-of-the-box, it is not possible to have these options appear as buttons for the user on the Universal Login page, however, this can be developed on a custom login page with Auth0.js.
The webAuth.passwordlessStart method accepts a connection parameter, and the value must be either email or sms . It is just a matter completing the following:
- Enabling both sms and email connections on the application.
- Designing a custom login page to give the user a choice.
- Passing the appropriate parameters to webAuth.passwordlessStart in the custom login page.
