About this app

Identizen turns your phone into your login. There is no password to type, reuse, or leak: a key is created on your phone, never leaves it, and signs each sign-in with your fingerprint.

HOW IT WORKS
• A site that uses Identizen shows a QR code and a two-digit match code. Scan it, check the code, approve with your fingerprint. You are in.
• After the first login from a browser, that browser is paired: the next login arrives on your phone as a notification. One tap.
• On a computer with Bluetooth, the site can find your phone nearby and skip the QR entirely.

SEE WHAT YOU ARE APPROVING
• Sensitive actions such as a wire transfer show the exact amount and payee on your phone before you approve. What you see is what gets signed, so a look-alike site cannot reuse your approval.

YOU HOLD THE KEYS
• Every site gets a different identifier for you. No email, name, or phone number is shared.
• See every browser and session that can sign you in, and unpair or sign out from your phone.
• A 24-word recovery phrase restores your identity on a new phone. Nobody else can.
• Your identity can live on more than one index, for example your employer's, and you switch between them in the app.

OPEN SOURCE
• Identizen is an open-source identity protocol (Apache-2.0). Sites integrate it as a standard OpenID Connect provider. The code is at github.com/identizen/platform.

Try it at jtmerlin.com, a demonstration bank built to show Identizen in action.
Your phone is your login. Passwordless sign-in, open source.
