Verdict

The call

The clearest difference is rating: All at 4.8 against Authenticator App's 3.0. All also leads on ratings volume (17 vs 2). Authenticator App's advantage is ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
