Changing MFA credentials of system

You can change multifactor authentication credentials for the system with the management GUI or command-line interface (CLI).

If credentials are updated on the multifactor authentication provider, these new credentials must be changed on the system. If the credentials are not updated on the system, the system cannot communicate with the authentication providers and user cannot be authenticated to access the system.

Using the management GUI

To update multifactor authentication credentials on the system, complete these steps:

Select Settings > Security > Multifactor Authentication.
Select the Authentication provider to change the credentials.
In Authentication server enter the correct host name and port number.
