How Does 2FA Work?

When you enable 2FA, you'll typically start by entering your password into a website or app. Once you're done, you'll verify your identity through a second form of authentication.

2FA can take many forms. Some services will send you a text message or email with a code; in others, you'll need to scan a QR code. Other examples of 2FA include opening an app and selecting a number, while others will require you to move your finger along a slider or enter biometric information.

Considering the tricks used to hack passwords, having more than one form of authentication can protect you. Even if someone cracks your password, they still have to verify their identity in another way that they normally wouldn't have access to.

Even so, you should still use strong passwords to prevent people from breaching your first line of defense whenever possible. There are a number of online password generators that can generate secure random passwords.

If you're not using 2FA, you're putting yourself at greater risk than you need to.

While the steps may vary by service, try using an authenticator app if possible.
