What is a Passkey and Why Should Your Business Use Them?

Published July 2026

Running a business comes with plenty of challenges, but keeping your digital infrastructure safe shouldn’t be one of them.

Last year, 43% of UK businesses fell victim to a cyberattack.

The vulnerability? Passwords.

Traditional passwords and standard text codes can no longer stop sophisticated digital scams. Protecting your company data requires a stronger, phishing-resistant line of defence.

Cyber criminals are constantly finding clever new ways to gain unauthorised access to private networks. When a data breach happens, the fallout can disrupt your entire operation, damage your customer relationships, and impact your cyber insurance policies.

Fortunately, cybersecurity for business is evolving to meet these challenges. Our new passkey solution is an easy and effective way to protect your daily operations and keep your business running smoothly.

Moving From Traditional Multi-Factor Authentication to Phishing-Resistant Security

Many business owners ask us: “What is a passkey exactly?”

Put simply, a passkey is a modern authentication method that can significantly reduce reliance on traditional passwords, while providing stronger protection against phishing attacks. A win-win.

You most likely already use traditional multi-factor authentication, such as receiving a text message or opening the Microsoft Authenticator app. While traditional MFA provides an important layer of protection, sophisticated phishing attacks can sometimes capture these credentials in real time through convincing fake websites.

This is where phishing-resistant security comes in as a new necessity for businesses.

A passkey is tied to one specific device and the real website or service you want to use. Even if someone mistakenly clicks a link from a phishing email, the passkey won’t work. There are no codes to steal, authentication to replicate, or tricks for hackers to use to get in.

 

Why Your Old Password Policies are Failing

Let’s look at a common mistake many businesses make.

We often see companies relying on strict password rules that force employees to invent complex combinations and change them every time they’re logged out! In reality, this approach usually backfires. It leaves frustrated staff reusing the same variations across multiple websites, writing them down on sticky notes or logging them in unprotected digital documents. Even with a password manager in place, organisations are still reliant on credentials that can potentially be disclosed through social engineering or phishing attacks.

Passkeys significantly reduce many of the risks associated with passwords because authentication relies on cryptographic credentials rather than shared secrets. Instead of relying on a secret string of characters that can be guessed, copied, or accidentally handed over to a scammer, it uses a unique digital signature that stays locked inside the physical hardware.

When logging in, your employee simply confirms their identity with a quick facial scan, fingerprint, or local PIN. Because the device handles the verification behind the scenes and only talks to a completely legitimate website, teams cannot be tricked into giving their access away. In turn, it ensures your business stays secure while making daily access incredibly streamlined and efficient.

 

Choosing the Right Security Tools for Your Team

Every workplace operates differently, which is why our passkey service focuses on absolute operational flexibility. We can deliver phishing-resistant security through 2 main methods, depending on your environment:

  • Company-managed devices: We configure passkeys directly into the standard business laptops and mobile devices your staff uses daily.
  • Hardware security keys: For shared workstations, hot-desking, or higher-security environments, we deploy physical FIDO2 security keys, such as industry-leading YubiKeys. Employees just plug the physical device into their workstation to verify their identity instantly.

Fitting Passkeys into your Wider Cyber Strategy

Passkeys are a powerful upgrade, but they cannot protect your business in isolation.

Think of a passkey as a highly secure digital lock on your front door.

If you leave your windows wide open by failing to secure the rest of your business network, you are still essentially inviting cyber criminals straight inside. A truly resilient defence requires layers. To ensure your sensitive data remains completely secure, implementing phishing-resistant MFA must go hand-in-hand with basic digital security like regular file backups, restricting user access to internal files, and keeping all your software updated.

When you combine passkeys with robust network security tools, such as a managed virtual private network and strong firewalls, you create a significantly more resilient security posture that helps reduce the risk of account compromise and unauthorised access.

Ready to upgrade your cyber security? 

Our new cybersecurity passkey service helps your business stay secure online and stay safe against phishing scams. Get in touch with our expert team about getting your passkeys set up.

 

A passkey is a modern login credential that replaces traditional passwords and password managers entirely. Instead of typing a code that can be stolen or guessed, your device generates a unique cryptographic pair during setup. To log in, you simply verify your identity locally using facial recognition, a fingerprint reader, or a local PIN.
No. Unlike passwords or text message codes, passkeys are completely device-bound and use private key cryptography. Because the private key never leaves your specific device and is never shared with external servers, cyber criminals cannot steal it through traditional phishing attempts or database hacks.
We understand that accidents happen. If an employee loses a phone or a physical security key, our team can quickly revoke that specific device's access through your central identity platform, such as Microsoft Entra ID. We can then easily provision a backup key or configure a new managed device so your business keeps running smoothly.
Traditional multi-factor authentication often relies on text messages or push notifications, which hackers can bypass using real-time phishing scams or social engineering. Passkeys are explicitly phishing-resistant because they are tied to a legitimate domain. They refuse to authenticate on fraudulent websites, completely protecting your sensitive information.
Yes, major operating systems and modern platforms fully support passkeys, and the list of compatible services is growing daily. For tools that your business relies on every day, our team will look at your setup and configure custom conditional access policies to ensure a seamless rollout.
Many insurance providers now require robust security measures before granting coverage or offering lower premiums. Implementing a phishing-resistant authentication protocol satisfies strict access management requirements, demonstrating to providers that you actively protect customer information and shield your network from common cyber-attacks.
