What you are probably seeing

You are managing user authentication and see security risks with passwords.

You want to reduce password resets and improve user experience.

Why it happens

Passwords are often lost, reused, and targeted by attacks.

Passkeys use public-key cryptography, reducing reliance on secrets users must remember.

What changed recently

Step by step

1. Identify which parts of your login flow depend on passwords.

2. Evaluate if your backend supports WebAuthn or passkey protocols.

3. Test passkey sign-in and sign-up on your current stack.

4. Plan a fallback for users who cannot use passkeys.

5. Update your documentation and user support to cover the new login method.
