Passwordless Authentication
Passwordless authentication is a security method that verifies user identity without requiring a traditional password. Instead, it relies on alternative factors such as biometrics (e.g., fingerprint, facial recognition), possession-based tokens (e.g., hardware keys, mobile apps), or magic links sent via email or SMS. This approach aims to enhance security by eliminating password-related vulnerabilities like phishing, weak passwords, and credential stuffing attacks.
Developers should implement passwordless authentication to improve security and user experience, particularly in applications handling sensitive data (e.g., banking, healthcare) or where user convenience is critical (e.g., consumer apps). It reduces the risk of breaches from stolen passwords and simplifies login flows, making it ideal for modern web and mobile applications that prioritize both safety and usability.
