Why is my password reset?
Passwords are automatically reset whenever a fourth new IP range is used to access your account. This is done to deter account exploitation.
If you work from multiple locations or computers, check the "Keep me logged in" button (and don't click logout) and the website will keep you automatically logged in and bypass the IP check. You might need to log off and sign back in to see this option.
