# Otpkey Authenticator vs Authenticator App

Authenticator App also leads on ratings volume (86 vs 2) and update cadence (every 2 weeks vs every 2 months). Otpkey Authenticator's advantage is in-app purchases (none vs 6) and review sentiment (50% vs 29%). On price, ads and device support there is nothing between them.

Both are free to download. Authenticator App sells 6 in-app purchases, starting at $4.19 per 7 days. Otpkey Authenticator asks for nothing beyond the download.

Authenticator App holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Authenticator App has 86 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Otpkey Authenticator's written reviews are positive against 29% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.
