Verdict
The clearest difference is rating: Authenticator at 5.0 against Lie Detector Fingerprint Scan's 3.3. Authenticator also leads on update cadence (every 2 days vs every 47 months). Lie Detector Fingerprint Scan's advantage is ratings volume (9.4K vs 3) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
