Hey Jenkins Users!

Ever found yourself locked out of your Jenkins admin account and scratching your head on how to regain access? Don't worry; we've got you covered! In this quick guide, we'll walk you through the steps to reset your Jenkins admin password seamlessly.

Step 1: Stop Jenkins The first step is to halt Jenkins to ensure a smooth password reset process. You can do this by executing the following command:

sudo systemctl stop jenkins

Step 2: Edit config.xml Next, you need to modify the Jenkins configuration file. Open it using your favorite text editor (in this example, we'll use nano):

sudo nano /var/lib/jenkins/config.xml

Step 3: Enable Signup Within the config.xml file, locate the <disableSignup> tag and change its value from true to false. This step enables user registration, which is necessary to create a new user and reset the admin password.

Step 4: Start Jenkins Now that you've made the necessary changes, it's time to start Jenkins again:

sudo systemctl start jenkins

Step 5: Register a New User and Reset Password With Jenkins up and running, navigate to the Jenkins login page and register a new user account. Once registered, log in with the newly created account and proceed to reset the admin password through the Jenkins interface.

Step 6: Revert Changes After successfully resetting the admin password, it's essential to revert the changes made to the config.xml file to maintain security. Repeat steps 1 and 2 to stop Jenkins and open the configuration file for editing. Then, set the <disableSignup> tag back to true. Finally, start Jenkins again to apply the changes:

sudo systemctl stop jenkins
sudo nano /var/lib/jenkins/config.xml
sudo systemctl start jenkins

And there you have it! Your Jenkins admin password is reset, and your system is secure once again. If you encounter any issues or need further assistance, feel free to reach out. We're here to help!

Happy Jenkins-ing! 😊
