Do not use the same password everywhere.
Duplicate passwords and password re-use means you’re one mistake (a mistake made by somebody unknown at some website you’ve logged in on somewhere) away from massive problems due to what is called “credential stuffing”; just as soon as one website or service has one breach and leaks what are too-often-poorly-secured credentials, those sake credentials are tried (“stuffed”) everywhere else. A Bad Day often ensues.
Use unique passwords, and use iCloud Keychain or another password manager to keep track of the passwords.
Here? Use whatever MacForum has for a password reset mechanism.
If that’s also the same password elsewhere, time to change that password everywhere else it’s been used, too.
