Passkeys: The Password-Free Future and How Websites Can Adopt It

Passwords are hard to remember, often reused and easy to steal through phishing. Passkeys are a newer sign-in method that major platforms including Apple, Google and Microsoft now support.

How passkeys work

When you create a passkey, your device generates a pair of cryptographic keys. The public key is stored by the website; the private key stays on your device and never leaves it. To sign in, you confirm with a fingerprint, face scan or device PIN, and your device proves it holds the private key.

Why they are better

• Phishing-resistant: a passkey only works on the genuine website it was created for.
• No shared secrets: there is no password on the server that attackers can steal and reuse.
• Convenient: sign-in takes a moment, and passkeys can sync across a user’s devices through their platform account.

Adding passkeys to your site

1. Use the WebAuthn standard, or a service or library that implements it.
2. Offer passkeys alongside existing methods at first, so nobody is locked out.
3. Let users register passkeys after signing in, and prompt them at a sensible moment.
4. Provide clear recovery options for lost devices.
5. Keep two-factor authentication for sensitive actions where appropriate.

What to expect

Adoption is growing, but many people still need guidance, so explain the benefit in simple words. Over time, passkeys are likely to become the default way to sign in.
