Trying to recover admin account

Using Jenkins Ask a question
1

I inherited a system running jenkins, that no one knows the login credentials for. I have attempted to set useSecurity false, and even removed the securityRealm and authorizationStrategy completely. After saving the edits and restarting jenkins continues to prompt me for a username/password.

I have also attempted to edit the only users config.xml I can find " admin_2298606251186183466 " and replace the jbcrypt hash with one I have generated, but that doesn’t seem to be working either. I keep getting prompted for username/pass and it doesn’t like what I’m entering… tbh, I’m not even sure I’m using the correct username, the admin_2298606251186183466 config.xml shows a “full name” of “XXXX Admin” which i’ve tried, and admin Admin, Administrator etc… anything else I can try?

In the config file $JENKINS_HOME/Users/admin_2298606251186183466/config.xml
you can see the user details right
example:

<user>
  <version>10</version>
  <id>admin</id>
  <fullName>Admin</fullName>
  <properties>

If after saving the config.xml the Jenkins comes up again with security enabled you might have CasC enabled that will configure your Jenkins at startup.
