★★★★☆ Mikot SuperUser · Aug 5, 2026

I love it, transferring my data from Google Authenticator was seamless. The only problem I had was that when switching to syncing data to Proton, it erased my local codes without any warning. Overall a great app, I highly recommend for someone googling

★☆☆☆☆ DragonulRed · Aug 13, 2026

Qr code expired, or please use another ss from another folder error, bruh... Edit for devs response: I imported 10 qr codes from Microsoft by scanning a ss. After I tried to scan another ss and meet the error above, I tried another ss same error, change ss name, same error. I used the last version on this store. I don't want to contact you. I uninstalled it and move on.

★★☆☆☆ synonymist · Aug 22, 2026

In Android 17, Proton Authenticator will not read a file for importing codes, whether from Drive or locally. This is true as I try to initialize the app on a new Pixel 11 Pro XL, having switched from an older Pixel on which I used this app.
