Does Fastlane have a default `username`?

Question

I'm trying to replace a Fastlane Match username with a new one on a Mac. No matter what variables I export (MATCH_USERNAME, FASTLANE_USER) or files I edit on my machine (Matchfile), Fastlane keeps picking up a previous user when executing a plain fastlane match. If I use the command line -u flag to override, then things run perfectly fine.

Does Fastlane have some default username that gets cached on initialization? Is there a way to force this username to be removed or find where it's being ingested by Fastlane (I've tried removing from fastlane-credentials, but I'm told it doesn't exist)?

I've got a temporary workaround for the time being, but I wanted to know for future reference.

To recap, I have tried:

• Exporting new MATCH_USERNAME,FASTLANE_USER
• Editing the Matchfile to include the new username
• Removing the account from fastlane-credentials remove

The answer is "no". Fastlane does not store a default username; however, someone else could set an export in .bash_profile that overrides this in a CI pipeline, which is what I just discovered. Mystery solved.
