Rundown of Passwordless AuthenticationPasswords have protected our online accounts for decades, but they're increasingly becoming the weakest link in business security. With cyber criminals targeting passwords on an unprecedented scale, technology companies are investing heavily in alternatives such as passkeys and biometrics. Passwordless Authentication isn't just about improving security—it's also about making logging in simpler, faster and far less frustrating. While passwords aren't disappearing overnight, every business should understand where the technology is heading and how to prepare for it. |
For something we all use daily, passwords have to be on most people’s list for Room 101.
They've been forgotten, reused, scribbled on sticky notes, stored in spreadsheets and, in many cases, become the source of office-wide frustration after someone inevitably locks themselves out of an important account five minutes before a deadline.
Despite their flaws, passwords have remained the standard way of proving who we are online. But is all that about to change?
A growing number of technology companies are moving towards passwordless authentication, replacing traditional passwords with passkeys, biometrics and other forms of secure identity verification. It's a significant shift, but one that is driven by a simple reality: passwords are no longer keeping pace with the way we work.
Why passwords have become a security problem
When passwords first became commonplace, most people had a handful of online accounts to manage. Today, the average employee can access dozens of different applications every week, from Microsoft 365 and CRM platforms to accounting software and collaboration tools.
With so many accounts and passwords, people naturally look for shortcuts. They reuse passwords, create variations of the same password, or choose something memorable rather than something secure. Even employees who know the risks struggle to resist the temptation of convenience, and cyber criminals count on it.
Around 7,000 password attacks take place every second across Microsoft services.
The scale of password-related cyber attacks highlights just how valuable passwords remain to attackers, whether they're obtained through phishing emails, data breaches or automated credential-stuffing attacks.
The challenge isn't simply that passwords can be guessed. More often than not, they're stolen.
What is passwordless authentication?
Passwordless authentication is about replacing passwords with methods that are both more secure and easier to use.
Instead of asking you to remember and type a password, passwordless systems verify your identity using something you have or something you are. That might be your fingerprint, facial recognition, a trusted mobile device or a security key (more often known as a passkey).
If you've unlocked your phone with your face or fingerprint today, you've already used the same principle. The experience is quicker because there's nothing to remember, and it's more secure because there isn't a password for someone to steal.
Why are passkeys getting so much attention?
Passkeys have become one of the biggest developments in online security over the past couple of years, and for good reason.
Unlike traditional passwords, a passkey doesn't rely on a secret that you type into a website. Instead, it uses cryptographic technology to verify your identity. The private key remains stored securely on your device, while the website receives only the information it needs to confirm it's really you.
This makes passkeys the perfect deterrent against phishing attacks because there's no password to trick someone into revealing. Even better, no password for you to remember!
Billions of passkeys are already in use worldwide, and adoption continues to grow as more websites and applications follow the lead of Microsoft, Apple and Google in supporting the standard.
Better security that’s easier for users
Traditionally, stronger security means asking users to do more. Create longer passwords. Change them regularly. Add special characters; The list goes on. It's no wonder password managers have become so popular.
But with passwordless authentication, security is improved while users do less! Signing in with your fingerprint or approving a request on your phone is usually faster than typing a complex password, and it removes many of the habits that attackers have relied on for years, such as using your middle name with your DOB tagged on for good measure!
Microsoft has reported that users signing in with passkeys experience higher sign-in success rates than those using passwords.
Will passwords disappear completely?
Not quite. Passwords aren't going to vanish overnight, and most businesses will continue using them in some capacity for years to come. Many older business applications simply weren't designed with passwordless technology in mind, and replacing them isn't always practical. What we can expect is more a change in the direction of travel.
Microsoft has begun making passwordless sign-in the default option for new consumer accounts, while many software providers now support passkeys alongside traditional login methods. As organisations upgrade systems and adopt newer cloud services, passwordless authentication is becoming less of a novelty and more of an expectation.
It's similar to the way multi-factor authentication evolved. Ten years ago it was seen as an optional extra. Today, cyber security professionals would consider it a basic requirement.
What does this mean for your businesses?
As a business, you should begin by understanding which systems already support passkeys and passwordless login. Microsoft 365 and many cloud-based applications already offer these capabilities, and adoption is likely to increase over the next few years.
This is also an opportunity to review broader identity management. Passwordless authentication works best alongside sensible access controls, multi-factor authentication where appropriate, well-managed devices and regular staff awareness training.
By starting preparations now, you’re likely to find the transition much smoother than those who wait until passwordless technology becomes the default.
We can help you move with the times
While passwords aren't disappearing tomorrow, the momentum behind passwordless authentication is unmistakable. As a change that’s likely to make life easier in the long run, it’s one many businesses will be keen to adopt as soon as possible.
