Apple has taken a significant step forward in enhancing Mac security by introducing passkeys as a replacement for traditional passwords. This new technology utilizes biometric authentication, such as Touch ID or Face ID, combined with public key cryptography to provide a more secure and seamless login experience. With passkeys, users can access their accounts without ever needing to type a password, significantly reducing the risk of phishing and data breaches. Apple’s iCloud Keychain now stores these passkeys securely, utilizing end-to-end encryption to protect user data even from potential breaches. This innovation marks a major advancement in digital security, offering users a stronger defense against cyber threats.
