Passkeys are a passwordless authentication method that replaces traditional passwords with cryptographic key pairs, enhancing security and user convenience. A private key is securely stored on the user’s device, while a public key is registered with the service. During login, the device verifies the user’s identity without transmitting the private key, making passkeys highly resistant…

Passwordless Authentication eliminates traditional passwords, enhancing security and user experience through biometrics, security tokens, magic links, and passkeys. Instead of relying on passwords, authentication is based on fingerprint scans, facial recognition, hardware tokens, or one-time codes. Key benefits include phishing resistance, reduced IT costs, and improved access security, though challenges include implementation complexity and device…
