biometric authentication for WordPress login

[Paul Schmidt]

Has anyone implemented biometric authentication (like fingerprint or Face ID) for WordPress logins?

[wisly.k]

Yes, biometric authentication (like fingerprint or Face ID) can be implemented for WordPress logins, though not natively. This is made possible by integrating WebAuthn (Web Authentication API) standards, which enable passwordless and biometric logins in modern browsers and devices.

To enable biometric login, you’ll need to install a plugin that supports it. Popular options include:

• Solid Security Pro
• Secure Passkeys
• Biometric Authentication
• AwareID
• Biometric Login for WooCommerce

How does it work?

Most biometric plugins rely on the WebAuthn protocol, which enables passwordless authentication using public-private cryptographic key pairs. These keys are securely stored on the user's device and linked to your WordPress site, allowing login via Face ID, fingerprint, or device PIN.

1. Setup Process

After installing your chosen plugin, you’ll configure the biometric settings directly in the WordPress dashboard. Most plugins provide a user-friendly interface to:

• Register biometric devices
• Customize login behavior
• Offer users a profile page to manage their preferences

2. Biometric Login in Action

Once enabled, users can authenticate by simply scanning their fingerprint or face on supported devices like smartphones or laptops. It’s seamless and takes seconds, no need to remember or type passwords.

3. Security Benefits

Biometric logins using WebAuthn are more secure than traditional passwords. They:

• Eliminate the risk of password theft
• Prevent phishing attacks
• Ensure login is device-specific (even if credentials are leaked, access is blocked without the device)

4. Fallback Option

For broader compatibility, most plugins also retain the standard username/password login as a fallback, ideal for users on unsupported browsers or devices.
