Circle ID Key

Sign in without passwords. Circle ID turns your device into your key—secure passkeys, one-tap AutoFill, and Face ID protection. Your identity, in your hands.

Your identity. Your device. Your key.

Circle ID replaces passwords with something you already carry—your phone. Sign in to apps and websites with passkeys, fill credentials in a single tap, and protect everything behind Face ID. No passwords to remember, reuse, or leak.

Why Circle ID • Passwordless sign-in — Log in with modern passkeys instead of passwords. Faster, and far harder to phish. • One-tap AutoFill — Circle ID plugs directly into iOS AutoFill, so your credentials appear right where you need them, in any app or in

Safari. • Face ID protection — Your vault unlocks only for you. Biometric security guards every credential on your device. • Set up in seconds — Scan a QR code to connect. No lengthy forms, no friction. • Strong encryption — Your keys and credentials are protected with modern cryptography, secured on your device. • Cross-device sign-in — Approve logins securely across your devices when you need to.

Built for the way you actually log in Passwords are the weakest link in security—forgotten, reused, and stolen millions of times a day. Circle ID is built on the passkey standard to make that problem disappear. Your credentials live on your device, unlocked by your face, and shared only with your explicit approval. Whether you're signing in to your favorite app, your workplace, or a website in Safari, Circle ID makes it effortless and secure.
