★★★★☆ American Joe · Aug 26, 2026
Could be better. Wish the pin unlock was not the same as the phone unlock. No way to change it currently.
★★★★☆ Rajnish Mishra · Sep 22, 2026
The Authenticator is amazing! I can add codes and get the number code, but, the problem is that even if you add a random code that isn't real, it still gives numbers so fix that Proton please (also 10/10 rating)
★★★★★ Mohamed Riyas · Sep 24, 2026
I previously used Aegis Authenticator, which offers more customization and quicker access to key features. Proton Authenticator is a great start, and I really appreciate Proton finally releasing a dedicated authenticator after years of requests from users, especially with cross-device sync. Please continue improving the UI, customization options, shortcuts, and overall user experience in future updates. Looking forward to seeing it mature
★★☆☆☆ Dan Jacko (Jako) · Aug 26, 2026
Sync between devices, ok already logged in but makes you log in again. While logging in, inset your Authenticator code, but im in the app trying to log in to sync, so I can't get the code??? Another issue, turned off biometrics on a device, now I cant use this App at all. Not even with a password.
★☆☆☆☆ Kyle K · Sep 14, 2026
The application does not have its own unlock apart from Google otherwise it would be 5 stars.
★☆☆☆☆ Red G · Sep 20, 2026
Was Swell but the swelling gone down now-you know what I mean? PROTON- smh Seriously?! I'm calling you out-your IT dept-needs serious help- want to hire me? Because it looks like you, Google, and everyone are in the same boat rn! Sad. I thought you were my only hope. Smh again no dumb developer comment allowed. I will be reaching out to your CEO happily. Shaking my head. S l o w l y. for the ones in the back!
★★☆☆☆ Quent L · Sep 15, 2026
Good but why does it have to take 200 MiB of space on my phone just to generate a few one time passwords?!
