Passkeys are modern authentication credentials that replace traditional passwords using cryptographic technology. They function through public-key cryptography, where a private key remains secure on your device while a public key authenticates with services. To use passkeys, register on a compatible website or app, then create a passkey through biometric verification—fingerprint or facial recognition—or a PIN.
During login, your device verifies your identity locally without transmitting sensitive data. Passkeys offer enhanced security since they're resistant to phishing attacks and data breaches. They're stored on your device, phone, or security key, ensuring convenient passwordless access while maintaining robust protection across multiple platforms.
