Auth Sync vs 2FA Vault

Auth Sync is a 2FA (TOTP) authenticator focused on privacy and simplicity. Generate and use OTP offline, then enable end-to-end encrypted cloud sync only when you need it. Your TOTP vault is encrypted on device—the server has zero knowledge. Highlights TOTP add & scan: QR scan, manual input, 6/8 digits, SHA1/256/512, 30s/60s. Folders & search, tagging, quick copy. E2EE cloud sync on demand; encryption keys never leave your devices. Secure sharing across your own devices (E2EE). Export/Import with encrypted backups; import from common authenticators. Extras: password generator, temporary email, Base64 encode/decode. Local encrypted backups to Files/iCloud. Security True E2EE with zero-knowledge backend. No collection of TOTP contents. Integrity checks to protect your vault. How it works Add accounts (scan QR or enter secret). Use offline codes immediately. Sign in to enable E2EE Sync across devices.
