Credential Reset initiated by user

We implemented a custom credential (2nd Factor) that we now want to get updatable by the users thru the ‘Credential Reset’ process. As an administrator we can start the process thru KC’s adminconsole:

  • [Users] → [Credentials] → [Credential Reset] → [Reset Actions “Update Custom Credenital”] → [Send Email].

So far so good.
But how can this process be initiated by the users itself?
