Summary

A simple application which generates TOTP tokens when multi-factor authentication is used with your Google account. It implements RFC4226 (HMAC-based OTP) and has been tested to work with Google Authenticator, Dropbox, Dreamhost and Amazon.

Not just to secure your GMail account, but also extremely helpful to tighten the security of your SSH connection as instructed at http://www.mnxsolutions.com/security/two-factor-ssh-with-google-authenticator.html

Instructions: Enter the secret you have been given by the service for which you want to have the OTP generated. Acccount name is whatever you want to remind your secret by, eg. the site name or email address. The generated 6 character key is the response you will need to enter when asked for. Be aware the time on your desktop or phone should be synchronized. When this is off by a minute it could fail to login.

If you are using Google, do not use an application-specific passwords to generate a response. They are not meant to be used this way.

Cannot import anything. No scanning support. Pointless

No documentation. No syncing, so can't import my existing 2FAs. Appears to only be useful if setting up a new 2FA - given I've already put all my 'at risk' accounts onto 2FA, makes this useless.

As soon as I installed this extension my inbox began being flooded with spam, it would seem the author is selling your email address and potentially other data.
