I need help with my password. I know what it should be but its not working.
@coco15 - There are some tips to try in this article: My Master Password is not being accepted. What should I do?
If those suggestions don't help, and you cannot remember your master password, you will be faced with starting over from scratch. No one can reset your master password, and you cannot change it without first entering the old one. That's part of the security and the reason why it is important to keep track of the master password somewhere safe.
Hopefully the information hawkmoth has shared proves helpful. If there is anything else we can help with, please let us know.
