# My OneSim vs Yubico Authenticator

The clearest difference is rating: Yubico Authenticator at 3.7 against My OneSim's 3.0. Yubico Authenticator also leads on ratings volume (287 vs 4). My OneSim's advantage is review sentiment (67% vs 43%) and iOS requirement (13.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Yubico Authenticator holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: Yubico Authenticator has 287 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of My OneSim's written reviews are positive against 43% of Yubico Authenticator's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
