Passkeys Are Not Magic, But They Are Better Than Passwords

Noel Bradford examines passkeys, a rare security improvement that reduces phishing risk and removes the burden of password memorisation. Drawing on NCSC guidance, he explains why passkeys are resistant to credential theft, how they use cryptography tied to the service you’re logging into, and why they can be easier for users than traditional passwords. He then offers practical adoption advice for small businesses: prioritise high-value accounts, choose approved credential managers, plan device recovery carefully, and train users without the hype. Passkeys won’t fix bad governance or unmanaged devices, but they do represent a serious upgrade from password-based authentication. For accounts that touch money, data, or admin access, this is progress worth planning properly.

Chapters

• Welcome Noel opens by framing passkeys as a rare security improvement that may make life safer and less annoying. He notes the NCSC recommends using passkeys over passwords wherever they’re available, and describes passwords as tired after decades of asking normal people to behave like flawless security robots.
• Why Passkeys Are Better Than Passwords Noel explains that passkeys move the security burden from human memory to devices proving identity properly. They are resistant to phishing because they use cryptography tied to the service, so fake sites cannot trick users into handing over reusable secrets. He offers practical adoption advice: prioritise high-value accounts (admin, finance, email, cloud), choose approved credential managers, plan device recovery, train users in plain English, and avoid half-rolled-out projects. Passkeys do not fix bad governance or unmanaged devices, but they do reduce credential theft risk.
• Outro Noel closes by saying passkeys are not magic, but they are a serious upgrade from passwords. They reduce phishing risk and password fatigue. Check which key business services already support passkeys, prioritise critical accounts, document recovery, train users, and keep strong passwords and multi-factor authentication where passkeys are not yet available.
