Figure out how to handle Keycloak and 2FA resets
Resetting the password allows the user (or attacker) to add a new 2FA device without 2FA, which makes 2FA basically useless. We can fix the issue, by disabling the Reset OTP element in the Reset Credentials flow (relevant doc), but it breaks Forgot Password for some(all?) users.
We also need to set a policy for 2FA reset. Is it just bad luck?
