What is Pass Key Pass Key is a new type of authentication technology that allows users to access their accounts without manually entering their password when logging into a website or application. Through the pass key, users can complete identity authentication using fingerprint recognition, facial scanning or device unlocking methods (such as PIN code). This technology is based on the encryption key pair mechanism, providing efficient and secure protection capabilities, and effectively resisting cyber threats such as phishing attacks. Advantages of Pass Key 1. Password-free login, which is more convenient to operate: use fingerprints, faces and other biometric methods to log in directly to the account, so as to save the hassle of repeatedly entering passwords and avoid login failures caused by entering the wrong password. 2. Stronger security: Pass keys follow technical standards formulated by the FIDO Alliance and W3C, and use asymmetric encryption algorithms to replace traditional secrets.
