Hello here!
I’m actually developping an SPI for my Keycloak for me to enable 2FA using SMS and such stuffs. Now I’m faced with an uncertain issue regarding the design.
Currently I have
- Two Authenticator SPI: One for getting the user’s Phone Number, the other one for verifying the sms TAN send to the requested phone number. The user should then be authenticated for the two of those.
- Two custom pages for requsting phone number and sms tan
I need the user to be able to change his phone number when he arrives on the request-tan-sms page. So I need to be able to navigate back when the user requests it.
But I have absolutely no Idea how to do it. So any help would be welcome 
Cheers.
Stephane.
