Passkey Authentication

Use biometrics or hardware security keys for the most secure and convenient sign-in.

Overview

Passkeys are a modern, passwordless authentication method using WebAuthn technology. They provide:

• Phishing-resistant - Cannot be stolen through fake websites
• No passwords - Nothing to remember or type
• Fast sign-in - Use Face ID, Touch ID, or Windows Hello
• Device-bound - Credentials stay on your device
