Online Authentication

Online authentication is the process of verifying a person's identity when they access an online service. This usually involves entering a username and password. The system checks these credentials against its database to ensure the user is who they claim to be. Additional security measures, such as two-factor authentication (2FA), may require a second verification step, like a code sent to a mobile device. The goal is to protect sensitive information and prevent unauthorized access, keeping personal data safe in an increasingly digital world.
