Over the last few days, the systems that handle passwords and logins was completely rewritten to use newest, more secured standards. During this process, some passwords has become broken and because we do not store people's original passwords, some people might have trouble logging in or changing their current passwords. If you are unable to login, use the forget password feature to reset it, otherwise, use the contact form to get in touch and I'll help you.
Also, Tapatalk is currently out-of-order because of this change, but I'm working on a fix.
