Is it possible to setup SMS based OTP's in Keycloak

Getting advice
1

I need to implement MFA in my application using username/password and OTP through SMS.
Is it possible to achieve this in keycloak.

Yes, itā€™s possible, but not ootb. You have to implement it in your own authenticator using the authenticator spi.
Have a look here in this example (not from me): https://github.com/gwallet/keycloak-sms-authenticator
