Identity on the Internet Computer

A Web3 authentication framework providing a Web2 login experience with blockchain security.

Internet Identity is a privacy-enhancing authentication framework to applications on the Internet Computer

Learn how it works

Biometric authorization

Unlock authentication with your device via FaceID, fingerprint sensor or use a YubiKey. This provides strong security, as the cryptographic key never leaves your device. No passwords are used to authenticate on the IC.

No tracking

Remain pseudonymous using the Internet Identity authentication framework, which prevents user tracking across dapps and services.


Internet Identity integrates the widely used secure web2 authentication framework known as WebAuthn for maximum compatibility.

Web3 security, Web2 convenience

We've all grown accustomed to managing hundreds of usernames and passwords, recovering forgotten accounts over text or email, unwittingly permitting companies to profit from our data at the cost of our personal privacy, all while falling victim to threats of identity theft and fraud.

On the Internet Computer blockchain, users can securely authenticate themselves without ever needing an email, username, or password. Using any WebAuthn-enabled device, users can login conveniently without their information being monetized by tech companies. Internet Identity is designed to prevent Web3 services to track your activity across dapps.

Focused on
privacy & security

By integrating dapps with Internet Identity, websites cannot track online user activity coming from other websites. Users have full control over their identities and access to Web3 services at their fingertips, while connections are private.
