You should not have to continually reset your password.
Some things that might be gumming up the works:
Browsers that 'remember' and autofill passwords often don't update when you set a new password and they autofill old info. Handkey your password for a while and see if it helps.
Password Lockers often have the same issue
Next time you access your account you can reset your password to something you like and find easy to remember. You don't have to use the auto-generated messy password the password reset form sends out.
Try something that is a phrase and insert a number or special character into it for a little extra security. example: Ibrake4merlot!
Passwords are case sensitive so make sure you don't fat finger the shift key
