Passkeys Are a Big Security Upgrade — But They’re Not the Whole Story

Passkeys are one of the best improvements to online security in a long time.

They are designed to replace passwords with a safer, easier way to sign in. That means no more reused passwords, much less risk from phishing emails, and far better protection against attackers trying stolen login details on lots of different sites. For users, they are simpler. For organisations, they are much stronger.

That is why passkeys matter.

But there is an important point that often gets missed: passkeys make the login much more secure, but they do not automatically secure everything else in the application.

Once someone is signed in, a website or app still needs to protect the user’s session, the pages they interact with, and important actions like changing account settings or approving transactions. If there are weaknesses elsewhere in the application, attackers may still be able to take advantage of them, even without ever stealing the passkey itself.

So the right way to think about passkeys is not “problem solved”.

It is: this is a major security improvement, but it needs to sit inside a wider secure application design.

That means businesses should absolutely adopt passkeys, but they should also keep investing in secure development, browser-side protections, session security, and extra safeguards around sensitive actions.

That is exactly what our new white paper covers.

It explains the major benefits passkeys bring, the types of attacks they stop, and the important security considerations that still remain after deployment.
