Introduction
Definition of Two-Factor Authentication
Two-Factor Authentication (2FA) is a security protocol that requires users to provide two different forms of identification before accessing an account. This typically involves something the user knows (like a password) and something the user possesses (like a smartphone app or a hardware token). For example, when logging into an online banking account, after entering your password, you might receive a text message with a code that you need to enter to gain access.
Significance of Two-Factor Authentication
The significance of Two-Factor Authentication cannot be overstated in today’s digital world. Cyber threats are rampant, and passwords alone can no longer provide adequate security.
Consider the following points:
- Enhanced Security: Even if a password is compromised, the second factor is required for access.
