Why didn't my One Time Password work during my Master Password recovery?
During the Master Password recovery function found at https://lastpass.com/recover.php , you will receive a link in your e-mail to use a One Time Password to login. You will need to try to use this One Time Password link in every browser that you have used to log in to the LastPass extension on your computer.
