Two-factor authentication (2FA) is a security measure that requires two separate factors to gain access—something you know and something you have. While it’s still important to have a strong, unique password to make it harder to crack (‘something you know’), 2FA also incorporates a randomly generated six-digit code that gets sent to or synced with a device you trust like your personal cell phone (‘something you have’).

What do I need?

There are a few different ways to get the 2FA code. One of the most common is to use your smartphone with an authenticator app or to have the code sent via text. You can also use password management applications from your computer, like 1Password, to add a 2FA code. All of the options have pros and cons, but some are more severe than others. For example, the authenticator app would need to be disabled or replaced before resetting your phone, but in general, an authenticator app is considered more secure than a text message code which can be diverted to a different device.

Although there are many different authenticator apps that you can use, some authenticator apps that we recommend are:

• Google Authenticator | iOS | Android |
• FreeOTP (Redhat Fork of GoogleAuthenticator) | iOS | Android |
• 2 Steps Authenticator (Blackberry)
