... reset them instead.
When you've forgotten your password, five successive failed login attempts will get your account locked for 24 hours. We do not do this to frustrate or annoy you, but to avoid having the site or server hacked, which has happened a couple of times in the past. It is a hassle restoring everything after a hack, and may cause the loss of a little content. Your Association also wants to keep certain information & data as secure as it possibly can, particularly the document storage area.
So, if you're struggling to remember your password it is best to request a reset before you get to the third guess. Information about resetting a lost or forgotten password is here.
You could also use the password manager in your web browser to remember your passwords. Browser password managers are generally reasonably secure these days.
