Want to create OTP based login (without 2FA)

Getting advice
1

I want to implement OTP based Login in Keycloak but it should be without 2 Factor Authentication.

In this it should ask for username/mobile/email in the first screen form and after validating the that existing user/mobile/email it should ask for OTP sent to his/her mobile/email.

Once OTP is validated that user should be logged-in.

Would be appreciate if anyone could help me on this.

Thanks in advance

I have the similar scenario.

In my case I just want to use keycloak like my OTP server, where the user need to put the OTP number when he take a specific action (ex: alter an information).

Any help will be welcome.
