Keycloak 2FA SMS Authenticator

Keycloak Authentication Provider implementation to get a 2nd-factor authentication with a OTP/code/token send via SMS (through AWS SNS).

Demo purposes only!

Unfortunately, I don't have a real readme yet. Blame on me!

But, for now, you can at least read my blog post about this autenticator here:
