Help getting access to Jenkins setup from previous user

Have a situation where a previous employee set up a Jenkins pipeline. He didn’t provide any username and passwords for other users to go in and update Jenkins Plugins. I explored looking into updating plugins manually with Jenkins CLI but it looks like it needs
an api token in order to install the updated plugins. The api token is created inside the Jenkins account. Anyway around this?

reset your security

you can also do it entirely from cli but won’t be able to get in and reconfigure anything if needed
