Allowed template variables are

  • {{identity.name}}: Name of the identity that is generating the secret
  • {{random N}}: Random string of N characters

Allowed template functions are

  • truncate: Truncates a string to a specified length
  • replace: Replaces a substring with another value

Examples:

{{randomUsername}}                              // 3POnzeFyK9gW2nioK0q2gMjr6CZqsRiX
{{unixTimestamp}}                               // 17490641580
{{identity.name}}                               // testuser
{{random-5}}                                    // x9k2m
{{truncate identity.name 4}}                    // test

Click 'Submit'

After submitting the form, you will see a dynamic secret created in the dashboard.

If this step fails, you may have to add the CA certificate.

7

Generate dynamic secrets

Once you’ve successfully configured the dynamic secret, you’re ready to generate on-demand credentials. To do this, simply click on the ‘Generate’ button which appears when hovering over the dynamic secret item. Alternatively, you can initiate the creation of a new lease by selecting ‘New Lease’ from the dynamic secret lease list section.

When generating these secrets, it’s important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.

Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret.

Once you click the Submit button, a new secret lease will be generated and the credentials for it will be shown to you.

​
Audit or Revoke Leases

Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard. This will allow you to see the expiration time of the lease or delete a lease before it’s set time to live.

​
Renew Leases

To extend the life of the generated dynamic secret leases past its initial time to live, simply click on the Renew button as illustrated below.

Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret
