About this app

Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in.
This means that in addition to your password, you'll also need to enter a code that is generated by the Google Authenticator app on your phone.

The verification code can be generated by the Google Authenticator app on your phone, even if you don't have a network or cellular connection.

* Sync your Authenticator codes to your Google Account and across your devices. This way, you can always access them even if you lose your phone.
* Set up your Authenticator accounts automatically with a QR code. This is quick and easy, and it helps to ensure that your codes are set up correctly.
* Support for multiple accounts. You can use the Authenticator app to manage multiple accounts, so you don't have to switch between apps every time you need to sign in.
* Support for time-based and counter-based code generation. You can choose the type of code generation that best suits your needs.
* Transfer accounts between devices with a QR code. This is a convenient way to move your accounts to a new device.
* To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. To get started visit http://www.google.com/2step

Ratings and reviews

I wish I could say I like the app. It works most of the time (when things are good), but: - It has issues syncing codes across devices: they are not in sync, and there is no "time sync" option in the settings anymore. - It will RANDOMLY DELETE ALL OF YOUR SYNCED CODES. I cannot stress enough how awful this is. They will disappear from your cloud account and then be summarily deleted on all devices that are connected to the internet. Given these flaws, I cannot recommend this app. Will try Aegis.

Biggest problem is the inability to go in and modify each entry. Some of my auth codes include the name of the website where those codes are used, but some just list by user ID. That's problemmatic when the user ID is just my email address. Please make the code names editable. I would also like to see the ability to remove entries for accounts or websites I no longer use. Other than those 2 items, I'm pretty happy with the app.

I love the app - works great! But wanted to let you know that after the most recent update it says syncing will continue once your device is online - even when my phone is online and has an active cellular or Wi-Fi connection. Not sure why this is happening or how to fix it. If I use the sync clock feature it just says it's already synced. Thanks so much for a great app and any suggestions to fix.
