Credentials Vault
The Credentials Vault provides secure storage of the usernames and passwords used by the robot workforce. The credentials are stored using a 2-phase encryption mechanism, which allows only Nintex clients to retrieve and decrypt the data and enter the credentials when required.
You can also access the Credentials Vault directly from Nintex Studio when you are developing wizards. See Accessing the Credentials Vault.
From Studio, all Credentials Vault credentials are available except credentials for the OS User.
