User authentication is the process that verifies the identity of anyone trying to access your business’s systems or data. By using methods like passwords, two‑factor authentication (2FA), multi‑factor authentication (MFA), or biometric verification, businesses can ensure only authorized users can access the information they’re meant to see.
