I have not change my password every single time I need to log-in. It just kept telling me that my password is incorrect. I can change my password according to the guidlines, get auto-login into the homepage, log-out, trying signing in again immediately, and it wouldn't work. I even tried changing the password through my auto-login page, but once I log out my password would stop working.
Also, it wouldn't let me proceed to change my password f it didn't have a capital letter, a number, no symbols and between 8-15 words anyways, so don't tell me that I need to adhere to the guidlines, I did. Tell me something new.
