I have installed bbpress and user able to login and change a password via a “generator” button. It generates a random password and email to user. All this are done in the edit profile page.

However I’d like a user upon login to allow them to edit profile and change to a desired password. If possible also prompt them to enter old password before proceeding.

The user can do this by editing their profile.

The do that by clicking their name or avatar anywhere on the site.

Now that is not obvious, so
