Lisatõendamine

Lisatõendamine refers to a security process that requires users to provide more than one piece of evidence to verify their identity. This is often implemented as a second factor of authentication, building upon the traditional username and password combination. The goal of lisatõendamine is to significantly enhance the security of accounts and sensitive data by making it much harder for unauthorized individuals to gain access, even if they manage to compromise a user's primary login credentials.

Common forms of lisatõendamine include one-time passcodes (OTPs) sent via SMS to a registered mobile phone, authentication codes generated by a dedicated authenticator app on a smartphone, or physical security keys that are plugged into a computer or tapped against a device. Biometric authentication, such as fingerprint scans or facial recognition, can also serve as a form of lisatõendamine. The choice of secondary factor often depends on the desired security level and the user's convenience. Implementing lisatõendamine is a widely recommended practice for protecting online accounts from various security threats like phishing and credential stuffing attacks.
