Welcome to the 'How to use Multifactor Authentication' video course. In this video, you'll learn how to use Multifactor Authentication, or MFA, to sign in online. MFA is when you use two or more different types of proof to verify your identity when signing in to your accounts online, such as your banking, email or government accounts. MFA can also be called 2FA, or two-factor authentication, and helps provide extra protection against anyone trying to obtain your personal or financial details.
The first step to verifying your identity when you sign-in to an online account is entering your username and a password or PIN. The second step is usually in the form of a one-time security code. The code is sent as a text message or email to the number or email address you provided when you set up or added MFA security to an account. It can also be generated in an authenticator app that you install on your mobile device. This is a more secure way to receive a one-time code, and some accounts may provide it as option.
In addition to a password and a one-time code, some accounts might require a third type of proof, such as a fingerprint or facial scan. MFA is compulsory on some online accounts and optional on others. For security, it's best to enable MFA whenever it is available. Now, let's look at how MFA works in practice.
For this demonstration, we'll sign in to myGov on a computer and receive the code on an Android phone. Using separate devices adds security, because even if someone knows your sign-in details, they will still need your phone to get access to your account.
From the myGov Home page, click the Sign in button at the top right. On the Sign in page, type your username or email address into the first box. In the second box, enter your password. Once you're sure both are correct, click the Sign in button. The one-time code will be sent to your mobile phone number, and the myGov website will display a screen asking you to enter the code.
To view the code on your phone, tap the Messages app. On an Android model, it's a white icon with a blue speech bubble. When the Messages app opens, the code should be at the top of your messages. Never share a code that's been texted or emailed to you, even if someone calls claiming to be your bank or the government. A real organisation will never ask you for this code. Now, on your computer, enter the six-digit code from the text message into the box, and click Next.
Once your home page appears, myGov has checked two types of proof, your email address and password, plus the code, and you have now signed in using Multifactor Authentication.
