Authenticator is a simple security tool that generates a security code for accounts that require 2-Step Verification. Authenticator supports any 30-second Time-based One-time Password (TOTP) algorithm, such as Google Authenticator. You can add accounts to Authenticator by manually entering your RFC 3548 base32 key string or by scanning a QR code.

    Really works well. I found a trick to get the QR scanning to work properly. I had to move my phone about 18" away from the monitor. Counter-intuitive since I thought closer would be better - I thought the barcode needed to fill the majority of the camera lens. It doesn't. Everything has worked for me now - setup Google, LastPass, Facebook, and Microsoft. The only reason it gets 4 instead of 5 stars is because when I scan the QR code, it usually inserts some additional text at the end of the alphanumeric sequence. It identifies the "issuer" - so it will say "&issuer=Microsoft..." or something else. I have to delete everything from the ampersand on. Other than that, all works perfectly, and that's not a big deal.

    For people claiming QR scanner doesn't work: try tapping and holding on code to give camera time to focus.
