Keycloak with user verification using SMS

Question

After looking at keycloak I could not find a way to do any SMS verification.

Do you guys have any extension or setup in order to allow user verification with SMS.

Thanks for your help.

Jonathan.

The best example I found was this one. He has a blog post and a 20 minute video to explain it. It was done December of 2020 and it built and ran right out of the box.

code for the above blog post: https://github.com/dasniko/keycloak-2fa-sms-authenticator

there's even a video https://youtu.be/GQi19817fFk

I believe this needs to be a custom authentication SPI in Keycloak.

There are a couple of nice examples that seem to solve your problem. In case keycloak-sms-authenticator doesn't solve your purpose, then you can take a look at the source code and tweak it according to your need.

the code is too old to run, the version is 2.2.1, now it's 11.0+ – meadlai Aug 26 '20 at 07:01
I am using keycloak 12.0. Was someone able to use this code with version 12? – Shamil Puthukkot Apr 15 '21 at 06:18
