gcsfs: Google security error for token='browser'

could I ask how you got one for pydata-auth? Is there any way for gcsfs to go through the same window?

At the time the verification process was a little bit different. I was able to verify https://pydata-google-auth.readthedocs.io/ as the domain. They’ve since changed the rules to require a top-level domain where you control the DNS attributes, so I wouldn’t be able to use the same process without buying a domain like pydata-google-auth.dev or something
