How to disable or reset security settings in Jenkins

Question

I have forgot the credentials to log in into Jenkins. Is there some way through which I can log in into Jenkins as an admin or by creating other user?

Answer 1

Go to config.xml file in var/lib/jenkins. In this file you will find a tag called <useSecurity>. You can change it to false from true to disable the login while using Jenkins. Now restart jenkins and now you will be able to create a new user using new credentials.

Answer 2

One other way would be to manually edit the configuration file for your user (e.g. /var/lib/jenkins/users/username/config.xml) and update the contents of passwordHash:

<passwordHash>#jbcrypt:$2a$10$razd3L1aXndFfBNHO95aj.IVrFydsxkcQCcLmujmFQzll3hcUrY7S</passwordHash>

Once you have done this, just restart Jenkins and log in using this password: test

Hope this helps!
