* '''Challenge Questions, delimited by semi-colons''' - You can set a series of challenge questions, all users will be prompted to select a [[Challenge Question]] on next login. Their answer will be stored and they will be prompted to enter this answer if they forget their password and click the activation link in the "Forgot password" email template.

:'''Note:''' An example of a good challenge question would be something that is simple, memorable, can't be guessed easily, and won't change over time.
