What is two-factor authentication?

Two-factor authentication is indeed defined as a method that requires two separate forms of identification. This security process enhances the protection of user accounts by combining two different elements: something the user knows (like a password or PIN) and something the user has (such as a mobile device or a security token). The implementation of two-factor authentication significantly reduces the risk of unauthorized access since even if one factor (like the password) is compromised, the second factor must still be provided to gain access.

This approach strengthens security protocols, making it much harder for attackers to access sensitive information without possessing both forms of identification. As cyber threats continue to evolve, two-factor authentication has become increasingly vital in safeguarding personal and organizational data against potential breaches.
