Lisätodennuskeinot

Lisätodennuskeinot are supplementary means of authentication used in information security to verify a user's identity beyond a single factor. This concept is often referred to as multi-factor authentication (MFA) or two-factor authentication (2FA) when two factors are employed. The primary goal of lisätodennuskeinot is to enhance security by requiring multiple, independent proofs of identity, making it significantly harder for unauthorized individuals to gain access to systems or data.

These methods typically fall into three categories: something the user knows (e.g., passwords, PINs), something the user has (e.g., a physical token, a smartphone), and something the user is (e.g., a fingerprint, facial recognition). When a system requires a user to provide evidence from two or more of these categories, it employs lisätodennuskeinot. For instance, 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).

The implementation of lisätodennuskeinot is crucial for protecting sensitive information, financial assets, and personal data. By adding layers of security, these mechanisms significantly reduce the risk of account compromise due to stolen credentials, phishing attacks, or brute-force attempts. Organizations increasingly adopt lisätodennuskeinot to comply with security regulations and to safeguard their digital infrastructure.
