Protect your digital accounts and data by enabling Multi-Factor Authentication (MFA).
What is MFA (or 2FA)?
Multi-Factor Authentication (MFA), sometimes referred to as 2FA (two-factor authentication) is a security control system requiring at least two verification methods to authorize access. MFA would also refer to more than two methods.
You may have seen this type of security before with services or websites that require it, such as using your user and password then providing a code sent via text message at login. This would be a MFA method using SMS as additional verification.
You can set up MFA using different methods, such as SMS or a code from an authenticator app such as Google Authenticator.
If using Facebook, for example, you can find this within Settings => Security and Login or with their support article here.
If using Twitter, from the side menu choose More => Settings and privacy => Security and account access => Two-factor authentication. You can learn more at Twitter’s help center here.
