How to find Tomcat default administrator password for various versions

Tomcat does not come with a default administrator password set up out-of-the-box due to security reasons. Instead, the administrator user must be manually configured.

To set up an administrator user in Tomcat, follow these steps:

1. Locate the tomcat-users.xml file in the conf directory of your Tomcat installation.
2. Edit tomcat-users.xml and add the following lines within the <tomcat-users> tag:

<tomcat-users>
    <role rolename="manager-gui"/>
    <role rolename="admin-gui"/>
    <user username="admin" password="admin_password" roles="manager-gui,admin-gui"/>
</tomcat-users>
    

3. Save the changes and restart Tomcat.

Accessing the Admin Interface

Use the following URLs to access the Tomcat Manager and Admin interfaces:

• Manager App: http://localhost:8080/manager/html
• Host Manager: http://localhost:8080/host-manager/html
