Hi Jacob,
as described here:
http://www.threetags.com/how you cannot change your
password at the moment, as this will render your existing data
unreadable. Sorry for the inconvenience. We will enable password
changing when we introduce offline access.
For now you can just create a new account with the new password:
1. accounts are free - create as many as you need
2. you can work with multiple accounts simultaneously (in different
tabs/windows)
Again, we will enable this feature soon, and sorry for the
inconvenience you have right now.
