How to Add Passwordless Login in WordPress with Multidots Passkey Login Plugin

If you still rely on usernames and passwords for WordPress, you increase risks for your site and users. Weak passwords, forgotten passwords, and phishing are common problems. The better way is passwordless login on WordPress sites that can be used today.

In this guide, you will learn how to add passwordless authentication in WordPress with the Multidots Passkey Login plugin. We explain what passwordless means, how passkeys work, how to set it up step by step, and where it shines in real sites.

Why Passwordless Login Is the Future of WordPress

Every WordPress admin knows the pain of password resets, forgotten credentials, and user lockouts.
Traditional login systems are slow, frustrating, and risky — hackers exploit weak or reused passwords every day.

That’s why more websites are switching to passwordless authentication in WordPress using passkeys. It’s faster, more secure, and feels like logging in with a phone’s Face ID — no password required.

In this article, we’ll show you how to add passwordless login to WordPress sites can use today with the Multidots Passkey Login plugin — powered by modern FIDO2/WebAuthn technology.

What is Passwordless Login in WordPress?

Normally, WordPress requires a username and a password to block unauthorized access.
But this method has two major flaws: users forget passwords, and attackers steal them.

A passwordless authentication WordPress setup solves both problems.
It lets users verify their identity through a secure device instead of typing a password.

With the Multidots Passkey Login plugin, users can log in using:

• Face ID or Touch ID on Apple devices
• Windows Hello on PCs
• A security key or device PIN

No more remembering passwords. No more reset emails. Just instant, secure access.

Why Choose Passwordless Authentication?

1. Stronger Security

The WordPress passkey login plugin eliminates password-related issues. Instead, it uses public-key cryptography (FIDO2/WebAuthn). Even if hackers breach your site, they can’t use what they find — no stored credentials exist.

2. Better User Experience

Users log in with a single tap or fingerprint. It’s frictionless and mobile-friendly — exactly what users expect these days.

3. Lower Support Costs

You’ll see fewer password-reset tickets and fewer “locked-out” users — saving time and support effort.

4. Future-Proof Technology

Passkeys are now supported by Apple, Google, and Microsoft, meaning your site aligns with global security standards from day one.

Password-based vs Passwordless: A Quick Comparison

Aspect	Password-based	Passwordless (Passkeys)
Credential stored on the server	Yes (hashed password)	No (only public key stored)
Vulnerability to phishing/reuse	High	Very low
User friction	High (remember/forgot/reset)	Very low (one tap)
Multi‐factor built in?	Depends	Yes (device + biometric/PIN)
Cost of resets/support	High	Lower

Switching to passwordless means removing the weakest link (the human-remembered password) and streamlining access.

Overview of Passkeys (FIDO2 / WebAuthn)

What are Passkeys?

Passkeys are modern credentials based on FIDO2 and WebAuthn. They let users log in without passwords. The key lives on the device or syncs through a trusted platform. The user confirms with a biometric or a local PIN. This is the core of a FIDO2 WebAuthn WordPress plugin.

How Passkeys Work

• Registration. The device creates a private and public key. Your WordPress site stores the public key. The private key never leaves the device.
  
• Login. The site sends a one-time challenge. The device signs it after biometric or PIN approval. Your site verifies the signature with the public key.
  
• Result. Strong, phishing-resistant login with built-in multi-factor.
  

Security Advantages and Compatibility

• Phishing resistance. There is no password to steal or reuse.
  
• Strong authentication. Biometric or device PIN adds local proof.
  
• Broad support. Major browsers support passkeys. Chrome, Safari, and Edge work on iOS, Android, macOS, and Windows.
  
• Future proof. Passkeys are backed by platform vendors and the FIDO Alliance.

How to Set Up Passwordless Login in WordPress

Follow these simple steps to add passwordless login WordPress functionality to your site using Multidots Passkey Login.

Step 1: Install and Activate the Plugin

Go to your WordPress Dashboard → Plugins → Add New,
search for “Multidots Passkey Login”, and click Install → Activate.

Once activated, the plugin adds a “Sign in with a passkey” button to your default WordPress login screen. Users can still log in with their password, but now they’ll see a new option: Sign in with a passkey.

Step 2: Enable Passkey Login

After activation, go to Dashboard → Passkey → Settings in your WordPress admin panel.

Here you’ll find the main configuration page with all the plugin’s options.

General Settings:

• Enable Passkey — Turns on passwordless login.
  
• Require HTTPS — Ensures passkeys only work over a secure connection.
  
• Session Timeout — Set how long users remain logged in (default: 300 seconds).
  
• Max Credentials per User — Limit how many devices can register a passkey.
  

Click Save Changes after configuring.

Step 3: Add Passkey Buttons Using Shortcodes

You can display the passkey login and registration buttons anywhere on your site using two simple shortcodes:

• Login Shortcode: [mdlogin_passkey_login]
  Displays a “Sign in with a passkey” button.
  
• Register Shortcode: [mdlogin_passkey_register]
  Displays a passkey registration form.

You can embed these shortcodes in:

• A login page or pop-up
• Member dashboard

This gives you full control over where users can register or use passkeys.

Step 4: Manage Passkeys

Admin can manage their registered passkeys right from their WordPress admin dashboard.

Admins can also see:

• Username and email
  
• Passkey status (Active/Inactive)
  
• Credential ID linked to each passkey

This makes it easy to monitor usage, revoke access, or reset credentials when needed.

Frequently Asked Questions About Passwordless Login in WordPress

1. Is passwordless login really more secure than using passwords?

Yes. Passwordless login is far more secure because it removes the biggest risk — passwords themselves.

The Multidots Passkey Login plugin uses FIDO2/WebAuthn, which relies on device-based private keys. These keys never leave the user’s device and cannot be phished, guessed, or reused. Even if someone gets access to your server, they still can’t log in without the user’s physical device.

2. Do passkeys work on all browsers and devices?

Yes. Modern browsers and platforms now support passkeys, including:

• Chrome, Safari, Firefox, Edge
  
• iOS and Android
  
• macOS and Windows
  
• Devices with Face ID, Touch ID, Windows Hello, or USB security keys

This makes passwordless authentication in WordPress setups seamless on both mobile and desktop.

3. Do I need HTTPS to use passkeys?

Yes. Passkeys require HTTPS because WebAuthn communicates sensitive authentication data. The plugin includes a “Require HTTPS” setting to ensure security. If your site isn’t using SSL yet, install an SSL certificate before enabling passkeys.

4. Do biometrics get stored on my WordPress site?

No — never.
Biometric data like Face ID or fingerprints stay on the user’s device only. Your WordPress site stores only a public key, which cannot reveal anything about the user’s biometric identity.

5. Is the Multidots Passkey Login plugin free?

Yes, the plugin is fully free and available on WordPress.org. There are no premium upgrades needed to use passkeys, shortcodes, or admin features.
