Firefox addon that generates TOTPs for 2 factor authentication
This addon shows TOTPs (Timed One Time Passwords) for accounts set up with 2 Factor Authentication/2 Step Verification.
Enter the site name and secret key in the addon's options page and click the check to add a site.
The codes will appear in the toolbar icon. The copy icon after the code copies the code.
