If you have been paying attention to security news lately, you have probably noticed a big shift happening. The UK's National Cyber Security Centre (NCSC) now officially recommends passkeys over traditional passwords for authentication. This is not just another tech trend—it signals a fundamental change in how we protect our online accounts and websites.
For WordPress site owners, this matters more than you might think. Your login page is often the first target for attackers, and passwords—no matter how complex—have some serious weaknesses. Let us break down what passkeys actually are, why they are better, and whether you should start using them on your WordPress site today.
What Exactly Are Passkeys?
Passkeys are a modern authentication method that replaces traditional passwords with cryptographic key pairs. Instead of typing in a password that could be guessed, stolen, or phished, you authenticate using something you have (like your phone or laptop) combined with something you are (your fingerprint or face) or something you know (a device PIN).
Here is how it works in practice: when you create a passkey for a website, your device generates two cryptographic keys. The private key stays securely on your device and never leaves it. The public key gets stored on the website's server. When you log in, the website sends a challenge that only your private key can answer, and your device handles the response automatically after you verify your identity with biometrics or a PIN.
The beauty of this system is that there is no password to steal. Even if someone hacks into a website's database, they only get public keys—which are useless without the corresponding private keys locked away on your personal devices.
Why the NCSC Says Passwords Have Passed Their Sell-By Date
The NCSC's official recommendation is a big deal. This is the same organisation responsible for protecting UK government systems and critical infrastructure, and they are now saying passkey technology is reliable enough for mainstream adoption. Their reasoning is straightforward: passwords have too many vulnerabilities that passkeys simply eliminate.
Think about the common ways passwords fail us. People reuse them across multiple sites, so one breach compromises everything. Phishing attacks trick users into entering passwords on fake login pages. Brute force attacks can crack weak passwords in seconds. Password managers help, but they add complexity and are not foolproof. Passkeys sidestep all of these problems because there is no secret to type, reuse, or accidentally hand over to attackers.
For website owners, this shift matters because your users are increasingly expecting modern security options. At TPC Hosting, we have seen growing interest from customers wanting to implement stronger authentication methods. The good news is that passkey support is becoming easier to add, and your visitors will appreciate the improved security and convenience.
How to Enable Passkeys on Your WordPress Site
Adding passkey support to WordPress is more accessible than you might expect. Several plugins now offer passkey authentication, with varying levels of features and complexity. The most popular options include plugins that implement the WebAuthn standard, which is the underlying technology that makes passkeys work across different platforms and browsers.
Before you dive in, make sure your hosting environment supports the necessary requirements. You will need HTTPS enabled (which you should have anyway), and your server needs to support the required PHP extensions. If you are hosting with TPC Hosting, you are already covered—our servers are configured to support modern authentication standards out of the box.
Start by installing a reputable passkey plugin from the WordPress repository. Configure it to offer passkeys as an option alongside traditional passwords initially—this gives your users time to set up their passkeys without locking anyone out. Once adoption grows, you can consider making passkeys the primary or even required authentication method for your site.
Best Practices for Rolling Out Passkeys
Transitioning to passkeys works best when you take a gradual approach. Enable passkey support as an optional feature first and encourage your team and regular users to try it out. Provide clear instructions on how to set up passkeys, since many people are still unfamiliar with the technology.
Keep traditional password login available as a fallback during the transition period. Some users may have older devices that do not support passkeys yet, and you do not want to accidentally lock out legitimate visitors. Monitor your login logs to see how adoption progresses and gather feedback from users about their experience.
Also consider enabling passkeys on your own accounts first—including your hosting control panel, domain registrar, and any other services that support them. At TPC Hosting, we recommend customers enable all available security features on their accounts, and passkeys are quickly becoming one of the most effective options available.
FAQ
Are passkeys safe if I lose my phone?
Yes, passkeys can be synced across your devices through secure cloud services like iCloud Keychain or Google Password Manager. If you lose one device, you can still access your accounts from other synced devices. You can also revoke lost device access from your account settings.
Do passkeys work on all browsers and devices?
Most modern browsers and devices now support passkeys, including Chrome, Safari, Firefox, Edge, and mobile platforms like iOS and Android. Older devices or browsers may not support them, which is why offering password fallback during transition is recommended.
Can I use passkeys and passwords together on WordPress?
Absolutely. Most passkey plugins for WordPress allow you to enable both authentication methods simultaneously. Users can choose their preferred login method, and you can gradually encourage passkey adoption while keeping passwords available for those who need them.
