# Yubico Authenticator vs Proton Drive

The clearest difference is in-app purchases: Yubico Authenticator at none against Proton Drive's 9. Proton Drive's advantage is rating (4.1 vs 3.7) and update cadence (fortnightly vs monthly). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Proton Drive sells 9 in-app purchases, starting at $0.99 per month. Yubico Authenticator asks for nothing beyond the download.

Proton Drive holds the better App Store score, 4.1 against 3.7. Both are backed by a comparable volume of ratings — 268 and 1.1K respectively. Written reviews complicate that: 44% of Yubico Authenticator's written reviews are positive against 37% of Proton Drive's, so the app with the better star average is not the one people write more warmly about.

Yubico Authenticator ships an update monthly, Proton Drive fortnightly. The most recent releases landed on September 14, 2026 and September 22, 2026 respectively.
