General help

Hi guys,

I've been trying to figure out a way to add another verification for when users change their password and so far I have not found a way to do so without modifying core.

A couple questions for you guys

• Is there a way to add a new password policy to moodle?
• Am I able to hook into the change password forms and add an extra verification step?
• Finally I was also planning on extending the change password forms and then overriding the verification function, however how can I tell moodle to use the child class?
