Passwordless authentication is a modern security method that eliminates the need for traditional passwords. Instead, it leverages alternative factors such as biometrics (fingerprints, facial recognition), one-time codes sent via email or SMS, or hardware tokens. This approach enhances user convenience, reduces the risk of password theft, and addresses common security issues like weak or reused passwords.
Multi-factor authentication (MFA) enhances security by requiring two or more verification factors to access an account or system. These factors typically include something you know (password), something you have (smartphone or token), and something you are (biometric data). MFA significantly reduces the risk of unauthorized access.
Single sign-on (SSO) simplifies user access by allowing them to log in once and gain access to multiple applications or services. With SSO, users don’t need to remember multiple passwords, improving both convenience and security. It streamlines the user experience while maintaining control over authentication processes.
