Passkeys were supposed to replace passwords, but they’re failing for the most predictable reason
Jul 23, 2026 | Guides
Passwords are a problem. Not only have they reached a point where a “strong” password is one no human can remember (much less remember dozens of them), but they simply aren’t as secure as they need to be. Passkeys combine a public and private cryptographic key pair with local authentication such as a fingerprint or facial scan. The device can prove its identity beyond doubt, and the assumption is that only you can unlock it.
