Is there a need to remove secret files created during pipeline? Edited

Consider the following pipeline snippet ($GCR_PASS is a secured repository variable):

- echo $GCR_PASS > keyfile.json
- gcloud auth activate-service-account --key-file=keyfile.json 

Is there a need to remove the keyfile.json at the end of pipeline? Or can I assume that this file will not be accessible again by any means?

Thank you.
