Credentials
Pronunciationkruh-DEN-shuhlz
Definition
Credentials are the data, such as usernames and passwords, used to verify the identity of a user or a system. They act as proof that an entity is who they claim to be before granting access to resources.
Where you hear it
Used during user authentication flows, API integration setup, and security audits.
Examples
Please ensure you do not hardcode your database credentials in the source code.
The application requires valid credentials to access the protected endpoint.
Common mistake
Confusing credentials with permissions; credentials prove who you are, while permissions determine what you are allowed to do after you have been identified.
