## What is DualisOne Authenticator?

DualisOne Authenticator generates the six-digit verification codes
used for two-factor authentication, keeping your accounts protected
with a second layer of security beyond your password.

EVERYTHING STAYS ON YOUR DEVICE

Your keys never leave your iPhone. There is no account to create, no
sign-in, and no server: the app makes no network requests at all.
Codes are calculated on the device from your stored key and the
current time, so they work anywhere — on a plane, underground, or with
no signal at all.

SIMPLE TO SET UP

Add an account in seconds by scanning the QR code shown by any service
that offers two-factor authentication. If you would rather not use the
camera, type the setup key in by hand instead.

BUILT FOR SECURITY

Your keys are stored in an encrypted vault, sealed with AES-256-GCM
using Apple's CryptoKit. The encryption key is held in the iOS
Keychain, restricted to this device and available only while it is
unlocked. There is no cloud backup and no sync, because your keys are
never transmitted anywhere.

FEATURES

• Six-digit codes that refresh every 30 seconds
• Add accounts by scanning a QR code or entering a key manually
• Works with any service supporting the TOTP standard (RFC 6238)
• Fully offline — no account, no sign-in, no network access
• Encrypted on-device vault protected by the iOS Keychain
• Clean, uncluttered interface
• Free, with no advertising and no in-app purchases

WORKS WITH THE SERVICES YOU ALREADY USE

DualisOne Authenticator implements the open TOTP standard, so it works
with any website or service offering authenticator-app two-factor
authentication.

Part of the DualisOne workspace suite.
