Comments on Proton Authenticator for Android

★★★★★ Simple and to the point, thank you proton also, I'm glad I was able to import my codes from winauth on my pc via qr codes, that saved a lot of time
★★★★★ I kinda like this app. Super simple UI and cloud sync, great! However, I found two things to be a little bit frustrating: I can't copy next codes, and the editing mode isn't intuitive. I initially thought editing wasn’t an option until I stumbled upon it accidentally. The app should offer users at least a hint that editing can be accessed by swiping left to right. I'd hope for more icons support or custom icon pack support, if possible. Thanks for reading.
★★★★★ This is very best app and have simple interface that we can manage codes easily, but proton authenticator should introduce notes in it, so we can manage our notes on it easily like authentication recovery codes etc
★★★★★ Upon reading the documentation, this app is great. It's secure and open source. It's also very easy to use. Unlike in Proton Pass, this one can store many 2FA codes, and it does not limit to 3, and you don't need an account to use it. Though, in mobile devices at least, I hope there is another way to unlock the app without using a biometric method. There should be an adjustable time limit to auto lock the app. Overall, this is a great 2FA authentication.
★★☆☆☆ Does not sync with Proton Pass natively, requires an export file. Codes created in the app do not transfer over to Proton Pass.
★★☆☆☆ I like proton products, and I uses it as my main provider, but this authenticator is frustrating, I can't login to sync it keep loading until show a toast 'Request timeout' only one time it worked for the username and when I entered the password the same request timeout happened
★★☆☆☆ Will not import from Google authenticator. Fail.
★★☆☆☆ ⚠️ BEWARE: highly concerned about security alert received via my android mobile device's Sophocles Mobile Security app, identifying Proton Authenticator app as a "LOW REPUTATION APP" likely due to: Few downloads or user base Not widely analyzed by security researchers Request potentially sensitive permissions Distributed outside official app stores
