There are a few hooks other than T110414 which are related to authentication (or authentication data change) and using them is a sign that the extension might benefit from an update after AuthManager is merged. Possibly incomplete list (I just searched `doc/hooks.txt` for hooks with "abort", "login", "auth", "session", "email" or "password" in the name):
