Your 2FA secrets should not be copied to someone else's cloud.

Attomus Signet is an offline OTP authenticator for security professionals and teams that want hard boundaries around authentication secrets.

• No account.
• No cloud sync.
• No server copy.
• No telemetry.
• No analytics SDKs.

Signet generates TOTP and HOTP codes on your iPhone. Secrets stay local, protected by iOS Keychain and device security controls. Access is gated by Face ID, Touch ID, or device passcode.

Encrypted backups are local files, not a cloud recovery service. Export to an Argon2id + AES-256-GCM encrypted .attomusauth file, choose your own passphrase, and save it where you decide. Attomus cannot read it, cannot sync it, cannot reset it, nor recover it.

Built for security-conscious users:

• TOTP and HOTP
• Standard otpauth:// QR codes
• iOS Keychain storage
• Face ID, Touch ID, or device passcode gating
• Encrypted local backup export and import
• App switcher privacy overlay
• No registration
• No advertising SDKs
• No Firebase or tracking SDKs
• No network requests for OTP generation, storage, export, or import

Signet is for people who do not want their authenticator to become another account, another sync service, or another third party in the trust chain.

Your codes. Your device. Your boundary.
