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 Permission notice: Camera: Needed to add accounts using QR codes

Very frustrating app. The instructions, in my opinion, are vague at best. I installed, attempted to set up several times, and was a miserable experience every time. Really wanted it to function, is the only app I have that doesn't seem to have complete guidance to get it rolling. Seems as if part of the puzzle is absent, incomplete directions at least. I gave up on this app. Wasn't worth the aggravation it was causing.

They just rolled out an update that desynced the rsa clock, so it's putting out codes that expire 15 seconds later, meaning half the time the app isn't even showing me a valid code. Despite my phone clock being perfectly synced with utc. Simultaneously it would appear the app also used to have a setting to trigger a time sync, because all the help in the help section for "my codes aren't working" talks about triggering a time sync. But, they removed that option from the settings. Nice...

"We've made the app easier to use and more visually appealing." You more than doubled the size of that font and it looks like trash now. Zero reason to not be able to adjust the size of the font ourselves instead of having some drop out UX designer decide they think font for an 87 year old is the best choice. And fix your damn broken clock sync. Jfc.
