Login_hint Has No Effect on Signup Prompt when Multiple Identifiers Are Enabled

Overview

There is a DB connection with multiple identifiers enabled via the Flexible Identifiers feature. When sending a login_hint parameter with screen_hint=signup (so that the Signup prompt will be displayed by default), the value in login_hint is not filled in any of the fields.

Applies To

  • Database connections
  • login_hint passed in the authentication request

Cause

This is by design since it is not possible to determine which field the login_hint should go in if multiple identifiers are enabled.

Solution

login_hint has no effect in this particular scenario. If this is a desired feature, please leave us feedback so we can consider it for a future iteration.
