Multi-factor authentication (MFA) is a security enhancement that requires you to present two pieces of evidence - your credentials - upon signing in. These credentials can be something you know such as your password, and something you have such as an application that generates a one-time passcode. MFA helps protect access to data and applications by adding an extra layer of security.

You have probably already used MFA in some form or another. For example, if you logged into a website that sent a code to your mobile device which you used to gain access to your account.
Note: If your VMware Cloud Services account is federated, MFA is managed by your enterprise security team.
Important:

For GovCloud customers, MFA is managed by your enterprise security team because all GovCloud customers use federated identity.
