Login procedure is a pain.

Hi there. Please fix the login procedure. I always type in the wrong password because you have it stared out for some reason.
If you're gonna do that, at least include a "show password" feature.
After I type in the wrong password, I have to delete the settings file because otherwise I get an error. This is extremely frustrating.
And it's not like I can copy/paste email and password into the settings file, because you're using some encryption thing.
Please either get rid of the encryption or let me see what I'm typing into the password field.
And if the login credentials are wrong, prompt me to the login screen again. Don't throw me an error message.
I can't use your addon because of all these annoyances.
And as a suggestion, maybe you can allow cookie login or activation code to make it easier.

Start by locating the login screen, password field, settings-file handling, and the credential validation flow described in the issue. Determine whether these requests can be scoped together; done would require a usable password-visibility option, recovery from invalid credentials without a settings-file error, and a clear decision on encrypted credential handling.
