Verdict
The clearest difference is in-app purchases: 2FA Authenticator (2FAS) at none against Password Generator's 4. 2FA Authenticator (2FAS) also leads on ratings volume (35K vs 9) and update cadence (monthly vs every 4 months). Password Generator's advantage is review sentiment (100% vs 77%) and iOS requirement (16.6 vs 18.6). On price and ads there is nothing between them.
