+include::../../../shared_content/secrets/rationale.adoc[]
+
+If attackers gain access to a BitBucket OAuth credentials, they will be able to interact with BitBucket API on behalf of the compromised account.
+
+=== What is the potential impact?
+
+Bitbucket keys allow external services to access resources on a user’s behalf with the OAuth 2.0 protocol.
+They are used to authenticate applications, services, or APIs using BitBucket for login and access-control.
+
+Below are some real-world scenarios that illustrate some impacts of an attacker
+exploiting the secret.
