With the rise of digital threats, traditional passwords are facing significant challenges. PassKey technology, based on the FIDO2 and Web Authentication standards, has gained widespread support and aims to replace passwords, enhancing both security and convenience.PassKey utilizes public-private key encryption to improve account security and optimize the login experience. When users register on platforms that support PassKey, the system generates a pair of keys:

Public Key : Stored on the server and used for identity verification. It cannot be used to impersonate the user.

Private Key : Stored on the user's device and exclusively used to generate digital signatures. These signatures are then verified against the public key.   

Users can log in using biometrics (such as fingerprints or facial recognition) or a local PIN, simplifying the process while improving security and convenience.PassKey technology effectively protects digital identities. It is recommended to regularly update software and browsers to the latest versions to enhance security further.
