TWO FACTOR AUTHENTICATION - COMPREHENSIVE GUIDE
Most services nowadays require signup and login procedures that are based on usernames and passwords.

To top it all off, every year billions of usernames and passwords are stolen and sold on dark web markets, and as a result, many users become victims to identity theft and data loss.
However, enabling Two-Factor Authentication (2FA) provides an additional layer of security and makes it harder for attackers to gain access to a user's devices and online accounts.
