Scan is not working. I confirm the permissions and change date. Restart and clear cash. But it is not working yet in my new phone...
★☆☆☆☆Leandro Vieira· Jul 20, 2026
I was signed in to Google Authenticator with the same Google account the entire time, and cloud sync was enabled. Despite that, all of my authentication codes suddenly disappeared and could not be restored. This has caused serious problems because I am now locked out of multiple important accounts. The entire purpose of cloud sync is to prevent this exact situation.
★☆☆☆☆Jerry Ngo· Jul 30, 2026
Major bug, if fingerprint is enabled to gain access to the app if you click or swipe back twice it will give you access to the 2fa codes. This needs to be fixed ASAP!
★☆☆☆☆Amanda B (ChocolateZephyr)· Aug 8, 2026
Didn't work for me, and you can't edit keys once entered. The help chatbot isn't much better. It's like nobody would ever want to edit something once entered. Totally useless.

App is showing codes without unlocking; even when the 'Privacy Screen' option is enabled. 👆🏼👆🏼👆🏼👆🏼👆🏼👆🏼👆🏼
