I'd say it's not just Google, but any third party authentication login supplier. In my case it's Wikipedia, but you may try most of the icons at the bottom of the login page.

Anyway, I've spent most evening trying to access OSM with JOSM. It used to work, I haven't used ir recently and something may have changed with recent updates. I'm using Ubuntu 22.04 with the stable JOSM version from PPA.

1) Snap based browsers for Linux may have something to do with that "The BROWSE action is not supported on the current platform!" message that kuroshiokun reported. I moved to install native Google Chrome with their .deb package and I got rid of it. But I had no luck with Oauth2 setup.

2) In my case Wikipedia gets stuck with a "Redirecting to ..." message. Watching console text I see no message about any failed or not tries to connect to ​http://127.0.0.1:8111

3) I tried to follow manual procedure to get an OSM Oauth2 token with no luck.
