Build env username variable keeps setting to my credentials

This started happening in the past month and I’m not sure of the cause/solution.

I login as username eg. “Simazine”.

Builds will fail due to credential errors. When I look at an existing configured pipeline, it seems the assigned username has changed from “user” to “Simzine”. All our pipelines use credentials we have setup and put in Jenkins, so for the binding we have “user” and “pass” in the text fields respectively.

What’s going on here?

Possibly someone installed the authorize project plugin or changed its configuration? That plugin is able to configure a job to run as the user that launched the build.
