Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in. With 2-Step Verification, signing into your account will require both your password and a verification code you can generate with this app. Once configured, you can get verification codes without the need for a network or cellular connection. Features include: - Automatic setup via QR code - Support for multiple accounts - Support for time-based and counter-based code generation To use Google Authenticator, you need to enable 2-Step Verification on your Google Account.

  • How do I set it up?

    No idea how to get it going. What bar code? Zero instructions. Bad dog.
  • Excellent

    Works excellent
  • No backuos

    I assumed the account were backed up, but when I moved to a new phone I lost everything. I'm now going through a very painful process to recover my accounts. Use any other app that includes backups. Duo, LastPass, Microsoft authenticator... Anything but this.

    I was once an android carrier until just today when I purchased my first IPhone. Had been using 2-factor authentication to log onto my Facebook acct, using the codes generated thru this app to complete the log in. Worked fine on my android, but with the IPhone the codes are not being accepted! Very frustrated because I am effectively locked out of my own Facebook acct! Help!!!

    This app isn’t supported by google. Lets say you get a new phone... all your codes magically disappear and you cannot retrieve them. Now, all the sites i used this 2fa generator will not let me in without lengthy exams that require hours, days of time waiting. Sometimes making it impossible to retrieve account access.

    The codes didn’t work now I can’t sign into my epic games account
  • Serious flaw (no backups)

    By SeizeTheBeat
    This app takes no cloud backups. I got a new phone and lost all my Authenticators I had stored. Spent weeks submitting paper work to get into my business accounts. I love google and their products, but this thing is an absolute joke. Even if your iPhone takes backups it will not restore the codes. Why is this not synced in a personal cloud or to google directly??? I suggest you use one that has an account sync, or one that’s integrated in a password manager (like 1Password’s “one-time password” feature). Google, I know you can do better than this.
  • Absolutely horrible

    By JwshBnkr
    This app is absolute garbage, I can’t even get codes to play games I bought because it won’t get them. The app only gives me the codes I have from google from getting it set up on my pc to get help. If I could give this less than a star I would made this review destroy their ratings
  • Good app!

    By JoyousCaribou48
    It was quick and easy! I tried using it on a older Samsung phone before but it didn’t work. It works fine on my current iPhone.
