What is the Default Username and Password for Jenkins?

When it comes to Jenkins, an open-source automation server, it is crucial to prioritize security by changing the default login credentials. The default username for Jenkins is usually 'admin', while the default password is an automatically generated initial password found in the Jenkins server logs. This initial password needs to be used to unlock the Jenkins setup process, where you can then create your own username and password.

However, it is highly recommended to change the default login information to secure your Jenkins instance. Using strong, unique passwords and enabling two-factor authentication can further enhance the security of your Jenkins server.
