Multi-factor authentication (MFA) is a way to prevent unauthorized access to your account. To log into your account using MFA you must provide two pieces of information to verify your identity, for example, your password and a one-time security code that we send to you when you log into your account. This means that if a criminal steals your password but does not have access to to view the one-time security code, they won’t be able to access your account.
Using MFA to log into an account
When you set up an account, you are prompted to select your MFA preferences, including how you want to receive your one-time security code. This is known as your authentication method. You can receive your code using one of the following:
- Text (SMS)
- An Authenticator app
When you log in, you are prompted for a security code if you:
- Have not set up MFA for your account
- Verified your identity more than 24 hours ago
- Accessed an account on a new device or a new browser
- Deleted your browsing data
