[keycloak-user] Using credentials from another provider in an authenticator - failing second time around

Hi All, I am currently developing an SMS based OTP solution, I¹ve hit a strange issue which I cannot fathom hence my asking here. I create a credential (which is the mobile number) in a required action, and then use it in an authenticator later on (this actually generates/sends the OTP) - during registration this works as expected, if the user returns and logs in, the authenticator is failing due to not getting a value for the credential ­ Am I missing something really obvious here? Code is all here: https://github.com/nickpack/keycloak-sms-authenticator-sns/tree/develop/src/ main/java/six/six/keycloak It is basically an adaptation of the Œsecret-question¹ example and some code I found that somebody else had started on for a previous version of key cloak. Thanks in advance, Nick
