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.
