App Description
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.

No collection of TOTP contents.
