Describes the methods in which Autonomous Database connects to other resources, either with credentials, or by configuring policies and roles for access.

• Manage Credentials
  You can create credentials, list credentials, or delete credentials in your Autonomous Database.
• Use Vault Secret Credentials
  Describes using vault secret credentials, where the credentials secret (password) is stored as a secret in a vault. You can then use vault secret credentials to access cloud resources or to access other databases (use anywhere that username/password type credentials are required).
• Configure Policies and Roles to Access Resources
  You may use the following methods to access cloud resources securely without storing user credentials: Oracle Cloud Infrastructure Resource Principals, AWS Amazon Resource Names (ARN)s, Azure service principal, or Google service accounts.
