Tugevdusautentimine

Tugevdusautentimine, also known as multi-factor authentication (MFA) or two-factor authentication (2FA) when two factors are used, is a security process that requires users to provide two or more verification factors to gain access to a resource, such as an online account. This method is designed to provide an additional layer of security beyond just a username and password.

The authentication factors are typically categorized into three types: something you know (like a password or PIN), something you have (like a mobile phone or hardware token), and something you are (like a fingerprint or facial scan). By requiring a combination of these, it significantly reduces the risk of unauthorized access, as a hacker would need to compromise multiple distinct security elements to gain entry.

Common examples of tugevdusautentimine include receiving a one-time code via SMS to your registered phone number after entering your password, using a fingerprint scan on your smartphone to log into an app, or inserting a physical security key into your computer. The implementation of tugevdusautentimine is widely recommended by security experts and is increasingly adopted by online services and organizations to protect sensitive data and systems. It is a crucial defense mechanism against common cyber threats like phishing and credential stuffing attacks.
