I want to describe How to Create An Auth Token in Autonomous Database.
1- If you’re an administrator creating an auth token for another user: In the Navigation Console (under Governance and Administration), click Identity, and then click Users. Locate the user in the list, and then click the user’s name to view the details.
2- On the left side of the page, click Auth Tokens.
3-Click Generate Token.
4-Enter a description that indicates what this token is for
5- Click Generate Token. The new token string will be displayed
6- Copy the token string immediately, because you can’t retrieve it again after closing the dialog box.
If you want to delete an auth token, click for the auth token you want to delete and click Delete.
