Understanding Two-Factor Authentication

Two-factor authentication (2FA) is a crucial security measure that adds an extra layer of protection to your accounts. Let's explore how it works and how to set it up properly.

What is 2FA?

2FA requires two different forms of identification before granting access to your account. This typically combines something you know (password) with something you have (phone or security key).

Types of 2FA

There are several types of 2FA methods available: - SMS codes - Authenticator apps (recommended) - Hardware security keys - Biometric verification
