## Description

"Two Factor Authenticator" is a tool for Firefox that enhances your digital security. Intended for accounts already set up with 2 Factor Authentication/2 Step Verification, it generates TOTPs (Timed One Time Passwords) that change periodically for added security. Just add the site name and secret key provided by your account, and the TOTP will show in the toolbar icon. It also allows convenient copying of the code with just a click. User keys are encrypted for security when a password is provided during setup.
