Passwords have been the weak point in business security for as long as most of us have been working. They get reused, guessed, written down, and handed over to convincing fake login pages. Every year we tell people to pick better ones, and every year it makes very little difference.
Passkeys are the industry’s attempt to stop patching the problem and remove it instead.
What a passkey actually is
When you create a passkey, your device generates a pair of matched keys. The public one goes to the service you are signing in to. The private one never leaves your device and is unlocked by whatever you already use — a fingerprint, a face scan, or your device PIN.
Signing in means your device proves it holds the private key. Nothing reusable is typed, and nothing reusable is transmitted.
Two things follow from that, and they are the whole point:
There is no secret to steal. A breach at the service end exposes public keys, which are useless on their own.
It cannot be phished. A passkey is bound to the real website address. Present a convincing replica on a lookalike domain and the passkey simply will not offer itself. The user does not have to spot the fake — the technology will not co-operate with it.
That second point matters enormously, because it removes the failure mode that catches even careful people.
What changes for your team
Less than you would expect, and mostly for the better. Signing in becomes: tap your name, confirm with the fingerprint or face unlock you already use to open your phone. Most people describe it as faster than what they were doing before.
The adjustment is conceptual rather than practical. People are used to a secret they know. A passkey is a credential their device holds. The first question is nearly always “what happens if I lose my phone?”
The honest answer about lost devices
This is the part worth planning properly rather than glossing over.
Passkeys sync through the account tied to your device ecosystem, so a replacement device signed into the same account gets the passkeys back. That covers the common case.
But you should still register more than one method per person — a second device, or a hardware security key kept somewhere sensible. And your IT support needs a defined process for re-enrolling someone who has genuinely lost everything, because that recovery route is now the softest part of the system. An attacker who cannot phish a passkey may simply ring your helpdesk and pretend to be a locked-out employee instead.
How to start without disruption
Do not attempt a hard switch. Passkeys and passwords can coexist, and the sensible route is gradual.
Start with the accounts that would hurt most if they were taken: administrators, finance, anyone who can move money or change permissions. Enable passkeys on your main identity platform — if you run Microsoft 365 or Google Workspace, support is already there.
Roll out to a small friendly group first and let them tell you where the confusion is. Then widen it, keeping passwords as a fallback until enough people have made the switch that you can start removing them.
The end state to aim for is passwordless for everyday sign-in, with a well-controlled recovery path behind it.
The bottom line
Passkeys are the first credential change in years that makes life easier for users and harder for attackers at the same time. You do not need to move everything at once. Start with the accounts that matter most, register a backup method for everyone, and make sure your recovery process is as strong as the sign-in you just improved.
FAQ
Are passkeys the same as multi-factor authentication? They replace the need for a separate second step rather than adding one. A passkey combines something you have (the device) with something you are or know (the biometric or PIN that unlocks it), so it is inherently multi-factor.
What if someone leaves the company? You revoke their access centrally, exactly as you would with any other credential. The passkey on their personal device becomes useless the moment the account is disabled.
Do passkeys work everywhere? Not yet universally, though support across major business platforms is now broad. Expect a period where passkeys cover most of what your team uses daily and passwords remain for the long tail.
