gmvault opens a browser window, where you confirm you want to give an auth token to gmvault. All without a password anywhere.

If you don't want to use the oauth token mechanism or if it doesn't work, you could also use your gmail password but it isn't recommended.

My point was that I don't want to use the password. Don't want it in my cronjob file, don't want it in my logfiles. It's really bad practice of programs to rely on the Password. On the bright side, gmail also allows you to generate application specific passwords.
