Backup problem. People think that the 2 factor authentication codes are linked to the Google account so when you sign in from another device all the 2 factor codes appear but that's not the case. One needs to be rooted to make a backup with titanium backup and restore to the new Android device in order to get the 2 factor codes on a new smart phone or tablet. I hope Google is working on a better way to move the codes to a new device. One can lock the app with an app locker application to prevent people from seeing the code
Now 5* after update Edit: with the option of dark mode, Google Authenticator goes back to five stars. Thanks for listening, developers! (Previous comment - "Got to agree with other commenters - the white background in the latest update is not good. Far too bright - if I want to use my screen as a lamp, then I'll do it with the profile screen I have set up for that purpose. Bring back the black background, if only as an option.")
Good app. Serves it's purpose of providing mfa. Codes are a nice fast 30 seconds ad apposed to 60 sec... my only gripe is when the code is nearing expiration it does not turn red. It does on all my peers iphones.. but not on my droid.
I like it as if gives me another way to use 2 step verification on many of my accounts letting me sign in without the need of my phone being online and without the need for me to get texts. However it seems that it isn't working correctly with my Facebook account for some reason it shows it should work but when I try it, I get "invaild code" when they match. Overall though works with all the other apps and sites I use so 4 stars, 5 when Facebook works with it.
Let's say I have 2 devices, device A and device B. Currently, for the same account, the Authenticator app only allows one device to have the codes. But what if that device gets stolen while unlocked? The person would be able to use the Authenticator app on your device and gain access to your accounts. Please add a feature to easily have Authenticator work on different devices other than the one it's installed on.
Need to offer a way to move to a new device with < 30' of work. The way it is this app should be withdrawn. You have to re-establish manually all your accounts. If you have been diligent and turned on two factor auth on all your important accounts, you are going to be punished. If your device is lost or broken, you may never recover your accounts. Amazon asked me to send an affidavit or to open a new account. You are warned.
