Lisätodentamismenetelmä

Lisätodentamismenetelmä refers to an additional authentication method used to verify a user's identity beyond just a password. This extra layer of security is commonly known as multi-factor authentication (MFA). The goal of lisätodentamismenetelmä is to significantly reduce the risk of unauthorized access by requiring more than one piece of evidence to confirm a user's claimed identity.

These methods typically rely on combining factors from three categories: something the user knows (like a password or PIN), something the user has (like a smartphone, security token, or smart card), and something the user is (biometrics such as a fingerprint or facial scan). For example, logging into an online banking service might require a password (something you know) and a one-time code sent to your phone (something you have).

Implementing a lisätodentamismenetelmä enhances security by making it much harder for attackers to gain access even if they manage to steal one of the authentication factors. If an attacker obtains a user's password, they would still need the second factor to successfully log in. This approach is widely adopted by organizations to protect sensitive data and systems from cyber threats.
