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
- Transfer accounts between devices via QR code

To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. Visit to get started.

I’ve never encountered such a poorly design application... theoretically, it seems cool, but in practice, it’s horrendous. I tried logging into my Nintendo account and for some reason needed this. So I got it, set it up for both my emails (this took forever, was annoying, and I got 2 because I couldn’t remember which it was... but I was sure it was one of them) and then tried entering it... nothing. Tried back up codes. Nothing. I went into the account and reset it, which was a pain, and tried again. Nothing. I tried multiple times of both types of codes and literally zip. I gave up. I wish that were the end of it. For some reason, all my accounts on all devices are signed out! It may be because I deleted some devices that said multiple weeks of inactivity, but the effected apps have been Google Photos and mail—applications they have control over and should notice if I log into it on one device or another continuously. Now, I’m stuck redownloading however many thousands of pictures and resigning into accounts. Hooray.

Upgrading deletes all your auth tokens! Buggy interface, no ability to backup connections.

2.0 upgrade deletes everything! How am I supposed to log into my accounts to re-add the tokens without my 2-factor auth? Thanks Google. Nice to see you care about your customers regardless of their platforms.

GET AN APP CALLED AUTHY! It supports auth tokens for Gmail, and every other service that Google Authenticator supports. AND Facebook and a many others that this app doesn't. And it's actively developed, has active support, and a GREAT interface. AUTHY!

More than 2 years without an update, despite all the bugs. Completely unacceptable!

Reordering the various accounts is buggy after adding a new account. As in it doesn't work. To make it work again I have to go to the legal info page, then back, then tap edit. Every time Previously ordered accounts randomly change order after tapping done and the new order is ignored. The red color for running-out-of-time gets applied randomly after attempting to reorder. Some stay red forever and the rest never turn red at all.

There is no ability to back up connections. If I get a new phone or have to restore this one from a backup I have to re-add every connection. To re-add connections I need to log in to the accounts that require the codes I can't get anymore until I connect. Which means I h e to start using one-time logins which is a MAJOR pain.

Locked out of exchange Acct

Ive been using Google’s Authenticator for a while with no problem to access my exchange website account. Then I had to get my phone restored. Little did I know my saved codes were also gone too. Now I’m trying to log into my exchange site account, but lo and behold my codes don’t show in the authenticator. At first I was extremely furious at the exchange site for having this cost of massive inconvenience for the sake of security. Then I realized it’s probably this app that should’ve warned us ahead of time that after a factory reset, all our codes will be gone. For the laymen user, we don’t have the time to read the fine print and learn about stuff like this, and if it’s very important it should be easily told to us. So I’m locked out of my Account for days, but hopefully my account won’t be gone forever. Never trusting this app again, and may try out that Authy app to see if it’s any better. Very frustrating...
