Username Template
string

Specifies a template for generating usernames. This field allows customization of how usernames are automatically created.Allowed template variables are
  • {{randomUsername}}: Random username string
  • {{unixTimestamp}}: Current Unix timestamp
  • {{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

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

​
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 the lease before it’s set time to live. Provision Lease

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