Comments on Proton Authenticator for Android

★★★★★ Sonya Harris · Jul 5, 2026
Exactly what I wanted, a free authenticator app that works! I've never had any problem with any of Protons services, and have been a paid user of one of their other services for many years now. Thank you to the Proton team.
★★★★★ Timothy Slazyk (Tim) · Jun 10, 2026
Superior to all others compromised systems. Just sayin' You'll figure it out the hard way. Hint: #DARPA The smartest thing any American can do is terminate their Facebook/DARPA account, but be sure to DELETE your data. Will the wicked truly delete your data? Probably not. Regardless, there is a process you MUST follow. Do this in preparation for what the Committee of 300 psychopaths has planned, and is implementing, ever so slowly, and systematically, #TotalitarianTipToe YOU HAVE BEEN WARNED!
★★★★★ Sean van der Merwe · Jul 14, 2026
Has some really nice features like fingerprint unlock, showing the next code for each login, etc.
★☆☆☆☆ Leonardo García (Leo) · Jun 3, 2026
The UI looks bad. I wanted to switch from Stratum since I'm an Unlimited subscriber, but I wasn't expecting that. Then on import, there's no feedback to let you know it's importing, so I ended up importing twice before it told me it had imported. Then I decided to log in with my account, and now I have several copies of the same codes. The login process is also annoying since it won't work seamlessly with Proton Pass (email then password, instead of both together). Not sure why they bothered.
★★☆☆☆ Dan Jacko (Jako) · Jun 30, 2026
Had to factory reset my device. All Authenticator codes I had were deleted. Now struggling to access any of my accounts. I didn't have a chance to back up, but I figured a paid app like this would save them. Very disappointed, at least google Authenticator saves them. This is enough for me to move back away from Proton. Can't even access my email.
