Authenticator

A password is one layer of protection. Two-factor authentication is a second. An encrypted vault for your most sensitive data is a third. Most security apps give you one of these. This one gives you all three — in a single place, locked behind Face ID, protected by end-to-end encryption and backed up to the cloud so you never lose access when you change your phone. This is built around three sections that work together to cover every part of your account security. SECTION 1 – AUTHENTICATOR Everything related to two-factor authentication and one-time passwords. Use this section when you want to secure any account that supports 2FA — social media, email, banking, crypto or any platform that offers it. TOTP code generation for any account that supports two-factor authentication — codes refresh automatically every 30 seconds, no internet connection required QR code scanner for fast account setup: point the camera at any 2FA QR code and the account is added in seconds Backup codes storage so you always have a fallback if your primary device is unavailable App Lock with Face ID keeps the authenticator inaccessible to anyone who is not you, even if your phone is unlocked SECTION 2 – PASSWORD MANAGER Focused on storing, organizing and protecting your login credentials. Use this section to replace scattered saved passwords, browser autofill and notes-app workarounds with a single encrypted manager. Store usernames, passwords and login URLs for every account in one encrypted location 2FA Encryption protects every entry so credentials are unreadable without your master authentication Generate strong passwords for new accounts directly inside the app Access your passwords across devices with Cloud Sync — everything stays current and encrypted in transit SECTION 3 – SECURE VAULT This is where you store what cannot be lost or exposed. Use this section for documents, recovery keys, private notes and any sensitive information that does not belong in a standard notes app or cloud folder. End-to-end encrypted storage for files, notes and credentials you want kept completely private App Lock with Face ID applies to the Vault separately, adding a second confirmation layer before anything inside is visible Cloud Sync keeps your Vault backed up and accessible across your devices without compromising the encryption All three sections share the same security foundation — 2FA encryption, Face ID protection and encrypted cloud backup — so every layer of your digital life is covered by the same standard of protection.

Verdict
The clearest difference is in-app purchases: REM at none against Authenticator's 2. REM also leads on iOS requirement (12.4 vs 18.5). Authenticator's advantage is update cadence (every 8 days vs every 6 weeks). On price, ads and device support there is nothing between them.
