User Reviews

Reviews are predominantly positive, highlighting Proton Authenticator’s strong privacy and security stance, polished UI, and ease of use. Users value its cross-platform reliability and built-in backup/import/export features, making it a favorable alternative to Google/Microsoft authenticators. The Proton ecosystem (VPN and password manager) reinforces trust. No widespread drawbacks are evident across multiple reviews; a few niche concerns exist but are not repeatedly reported.

Pros

Privacy-focused, Proton-brand security and strong trust in the Proton ecosystem
Excellent UI with intuitive use and good import/export options
Cross-platform reliability; does one job well as a 2FA authenticator
Backup/Import/Export features and flexible data handling
Viewed as a strong, privacy-centric alternative to Google/Microsoft authenticators within Proton’s ecosystem

Cons

Recent reviews

Does what it says it does and works most times, as with any such app it misses some forms where user and password input needs to be used and rarely it messes up providing only one part or providing it in the wrong field (probably site developers messing up field attributes not this app). The biggest issue I noticed so far was suggesting a new pass in places it shouldn't and storing that above the old one, you need pass recovery after this unfortunately (fortunately this happened rarely)
