# Thomson Reuters Authenticator vs Excelsior EMC

The clearest difference is rating: Excelsior EMC at 2.2 against Thomson Reuters Authenticator's 1.2. Excelsior EMC also leads on iOS requirement (12.0 vs 14.0). Thomson Reuters Authenticator's advantage is ratings volume (1.8K vs 6) and review sentiment (11% vs 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.

Excelsior EMC holds the better App Store score, 2.2 against 1.2. That said, the two scores are not equally well evidenced: Thomson Reuters Authenticator has 1.8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 11% of Thomson Reuters Authenticator's written reviews are positive against 0% of Excelsior EMC's, so the app with the better star average is not the one people write more warmly about.
