Keycloak Authentication with mobile number and otp

Question

I'm implementing the Keycloak authentication with vertx. I would like to customize login flow, instead of username/password form I want to login via mobile number and OTP.
Any one can help me if they have created any custom required action provider in keycloak.

Thanks in advance.

Answer 1

I think this would be doable in Keycloak now with Authenticator SPI. Please have a look on this code you will get to know you can revamp full login flow without much issue . Same can be rewrite for login from mobile number.

Please have a look this API keycloak-sms-authenticator,it will give much flexibility to do SMS based Authentication without writing much line of code.

Here is another good official documentation Custom User Attributes available how to use mobile number .
