Google Authenticator provides an essential extra layer of security by enabling two-step verification for your online accounts. Beyond just a password, you'll need to enter a unique code generated by the app on your phone each time you sign in, significantly reducing the risk of unauthorized access.

Key features include offline code generation, synchronization of auth codes across devices via your Google Account, easy setup through QR codes, support for multiple accounts, and flexible code generation methods (time-based and counter-based). Additionally, transferring accounts to new devices is seamless with QR code transfers. To utilize it with your Google account, simply activate 2-Step Verification at http://www.google.com/2step. Note: The app requires camera access to scan QR codes during setup.

Latest update knocked codes out of sync and they removed the ability to resync codes. Little to no support. If you look up how to fix, it says you need to sync your phone to your network provider now. Well, I've done that, reverse done that, tried changing timezones and reverting back, rebooting my phone, etc. The app would be 4 or 5 star, except for limited support and a bug from last update that hasn't been fixed in over 2 months. I literally get 10 seconds to enter code now.

Like most things, Google these days just doesn't work like it used to. After the most recent update trying to add an account using a barcode or entering the setup code doesn't do anything. There's no way to add new accounts. If you are in the same spot, just download the Microsoft authenticator app. It worked flawlessly the first time on the same QR code and I've used it for years.
