2FA (2 Factor Authentication)

2FA, or Two-Factor Authentication, is a security measure that uses two different types of proof to verify your identity before you can access an online account. First, you provide something you know, like a password. Then, you need something you have, such as a code sent to your phone.

Think of it as entering a high-security movie premiere. First, you need to show your ticket (similar to a password). Then, you need to wear a VIP badge that’s been given to you earlier (like the code sent to your phone). This double-layer of verification ensures that you are indeed the invited guest, keeping any uninvited fans or intruders away.
