Passkeys Explained: Are We Finally Done With Passwords
Passkeys are being pushed as a passwordless future. Here's how they actually work and where they still fall short.
Passkeys let you log in using your device's built-in fingerprint, face recognition, or PIN instead of typing a password, relying on cryptographic keys stored securely on your device rather than a shared secret that could be leaked or phished.
Why they're genuinely more secure
Because there's no shared password transmitted or stored on a company's server to be stolen in a breach, and the login can't be phished the way a typed password can, passkeys close off several of the most common ways accounts get compromised today.
Why the transition is still slow
Not every website or app supports passkeys yet, switching between devices and platforms can be inconsistent, and losing access to the device holding a passkey without a proper backup method can be more disruptive than simply forgetting a password, which is slowing full adoption.
