Secrets Wallet

The Secrets Wallet provided by Usage Engine allows you to securely store and manage your password/credentials. These secrets can then be added into the functions within your streams using the Stream Editor. For these reasons, it is highly recommended that you always use the Secrets Wallet.

This allows your function to connect with external systems and applications to collect or forward data without the need to input any credentials into the function, increasing the risk of exposure. Furthermore, having the credentials stored in the Secrets Wallet makes it easier to apply the same credentials across multiple streams.

An example of a Secrets Wallet being used is by creating an AWS secret and selecting the secret with the Secrets Wallet toggle button in the Configuration screen of an AWS S3 function.

Secrets Wallet Dashboard

You can view your secrets on the Secrets Wallet dashboard page. This page contains details such as Secret Name, Last Modified Date, Secret Type, and the Number of Streams the secret is currently used in. You can filter your secrets by type, or by typing the name of your secret in the Search box.

Secret Details 

Clicking on each secret expands the view to display the Details of the specific secret. This view contains two areas: 

  • Information area: Displays your Credentials and the Description of the secret.
  • Streams area: Displays all the streams using the secret. Clicking on the View button brings you to that particular stream.

Other actions

Click the Edit or Delete buttons to edit or remove the secret credentials from the Secrets Wallet.


  • You cannot delete any secret that is currently being used by a stream.
  • When updating a secret for a Scheduled stream, the changes will take effect from the next time the stream is run. 
  • When updating a secret for a Real-time stream, you must restart the stream for the changes to take effect.

In addition to the permissions specified for the various user roles available in Usage Engine described in the Admin page, there are some specific actions mentioned for the Secrets Wallet feature that must be highlighted:
