Ratings and reviews

My previous Android phone randomly died one day and wouldn't turn back on, so I lost my account and any way to log in to multiple apps. There is no way to import an existing account without scanning the QR code from the original device. If the device won't even turn on, it clearly can't provide a QR code to scan. This is completely ridiculous, and I can't believe even with all the complaints that there is still seemingly no workaround for this issue.

It would seem that I lost all keys I had during an OS update. Didn't think to make a backup, going to have to see if I have a historical one that I can use to restore system to previous state. Luckily I mostly migrated to Microsoft authenticator and a separate password manager so I didn't lose everything, but very inconvenient to reset the ones I did lose.

Still not secure. No way to backup accounts, no way to lock out anyone that gets access to your device. Even fingerprint authentication is better than nothing. But because there's nothing anyone that has access to your phone has access to this app. Plus if you lose your phone, you lose your accounts because there's no backup. Microsoft offers both of these features making their app much more appealing.
