Just don’t wipe your accounts

A lot of 1 star reviews come from people who wiped their accounts on their old phone and can no longer authenticate their accounts.

But if you don’t do that then this app is totally secure and does what it’s supposed to, and it’s safe to ignore the very low rating for this app.

iOS 15

After upgrading to iOS 15 all accounts are duplicated. However, deleting the duplicates also deletes the originals, locking you out of your accounts permanently unless you’ve saved your recovery codes. The solution is to uninstall & reinstall the app instead of deleting the duplicates. This is the second time this app has broken after an iOS update. Very scary. I expect much better from the one of the most successful software companies in the world.

A quick and fast way to lose your keys

Avoid this application as there’s no off-device encrypted backups. It’s on you to manually manage every single key manually. An upgraded handset can hard lock you out of anything this application is touching if you assume that app data will transfer across.
Have already spent 10’s of hours arguing with support staff on multiple platforms and incurring unforeseen costs recovering accounts. Google’s documentation for the service is sparse and inconsistent; complete fail for what should be the gold standard for an authenticator.
