What is Multi-Factor Authentication (MFA)?

Multi-factor Authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN. MFA is a core component of a strong identity and access management (IAM) policy. Rather than just asking for a username and password, MFA requires one or more additional verification factors, which decreases the likelihood of a successful cyber-attack.

If you have a service account and you want a particular group of members use this account in your organization, then we are using a very simple way without hampering security.

Here we are going to see how we can allow multiple users to use a Common or Service account using Multi factor authentication.

Go to click on Sign in option. Primary user will sign in with Username and password as a normal user do. If MFA is already setup for primary user, then Primary user doesn’t need to add MFA for the device. (In case Primary user wants to setup an account then follows step 1, 2 and 3)

Let’s see how to add MFA for rest of the users.
