Hi @fhefh2015,
Welcome to the Auth0 Community!
I understand that you have inquiries about using Auth0 in a Browser Extension.
Unfortunately, we do not have any documentation that describes how to accomplish this task.
However, this related Community Topic has a guide and solution on how to get Auth0 to work with Browser Extensions: https://community.auth0.com/t/ultimate-guide-to-auth0-in-a-chrome-extension-popup/61362/
Please let me know if there’s anything else I can do to help. I’d be happy to assist.
