Hardcoding secrets risks exposing sensitive data in logs or job configs. Using the Credentials plugin keeps secrets encrypted and secure.

intermediate

What is the difference between 'Global' and 'Folder' scoped credentials in Jenkins?

Global credentials are available to all jobs, while Folder scoped credentials are only accessible to jobs inside that folder, improving security by limiting access.
