Passwordless passkeys are transforming the way we approach online authentication. Traditional passwords have long been a weak link in cybersecurity, vulnerable to breaches, phishing attacks, and simple user errors. In contrast, passwordless passkeys use public-key cryptography to create a far more secure method for verifying identity. Rather than relying on passwords, which can be guessed or stolen, passkeys consist of a pair of keys: a public key stored on the server and a private key securely kept on the user's device.

Multi-factor authentication (MFA) enhances security by requiring users to provide two or more verification factors to access an account. Typically combining something the user knows (password), has (device or token), or is (biometric data), MFA significantly reduces the risk of unauthorized access and protects against cyber threats.

Single sign-on (SSO) simplifies authentication by allowing users to access multiple applications with one set of login credentials. After an initial sign-in, users can seamlessly access connected services without re-entering passwords. SSO enhances convenience, improves security, and reduces password fatigue, while streamlining user management for organizations.
