If you want a password to be the same across multiple direct connect sources, you can synchronize their passwords by combining the sources into a password sync group. For example, if your Salesforce, Workday, and Active Directory sources all use the same password, you can create a sync group for these sources. Whenever you change the password on one, the password will be automatically changed on all apps connected to those sources in the sync group.
