How to Reset Jenkins Admin Password?

You can reset the Jenkins admin password by following these steps:

1. Stop the Jenkins service. This ensures that no changes are made to the configuration while you're resetting the password.
2. Locate the Jenkins home directory. This directory typically contains the configuration files and data for Jenkins. You can find its location by checking the Jenkins installation or the system configuration.
3. Navigate to the config.xml file. This file contains the Jenkins configuration, including user credentials.
4. Open the config.xml file in a text editor.
5. Find the <user> element for the administrator account. This element will contain the username and password information.
6. Delete the <password> element. Removing this element will reset the admin password.
7. Save the config.xml file.
8. Restart the Jenkins service. This will reload the configuration with the reset password.

Note: This method will reset the password for the admin user. If you need to reset the password for other users, you'll need to locate their respective <user> elements and delete the <password> elements within the config.xml file.

Alternative Method:

If you have access to the Jenkins server, you can also reset the password through the web interface:

1. Access the Jenkins server through a web browser.
2. Log in with the admin username and password.
3. Navigate to the "Manage Jenkins" section.
4. Select "Manage Users" and then "Manage Users".
5. Locate the admin user and click on their username.
6. Click on the "Reset Password" button.
7. Confirm the reset action.

Important:

• Remember to keep your Jenkins server and configuration files secure to prevent unauthorized access.
• It's recommended to use strong passwords and implement security measures to protect your Jenkins instance.
