How Passkeys Stop Fake Login Pages from Stealing Your Login

A fake login page can copy the look of a real website. Why can’t it use your passkey in the same way it can steal a typed password? Learn how public and private keys, fresh challenges, and website-origin checks work together. We explain what a face or fingerprint check approves, how synced and device-bound passkeys differ, and how nearby-device sign-in works. Passkeys resist this kind of credential phishing; they do not remove every account-security risk. Password fallbacks and recovery methods still matter.
