Passkeys vs passwords: what changes for you

Passkeys promise a future with no passwords to phish. Here is what they are, how they work, and where they still fall short today.

Passkeys vs passwords: what changes for you

Passkeys promise a future with no passwords to phish. Here is what they are, how they work, and where they still fall short today.

A passkey is a key pair tied to your device and unlocked by your face, fingerprint or PIN. There is no shared secret to steal, so there is nothing to phish.

Why it is stronger

  • The private key never leaves your device
  • The site only ever stores a public key
  • Phishing pages cannot replay what they cannot capture

Where it is still rough

Recovery and cross-ecosystem sync are improving but uneven. Keep a password-plus-2FA fallback until passkeys are everywhere you log in.

Passwords are a shared secret. Passkeys are a proof. Proofs are much harder to steal.
