Verdict

The call

The clearest difference is ads: Auth Authenticator at none against Key's shown. Auth Authenticator also leads on ratings volume (28 vs 2). Key's advantage is update cadence (every 3 days vs every 5 weeks) and iOS requirement (12.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.
