Tried to log in to my Google Account from Chromium browser recently and got some weird "this is not an authorized browser" type message. Same thing happened with the mobile Lightning Browser (which is based on Chromium). Google trying to force me to use Chrome, specifically, rather than just Chromium-based browsers?
At least I can still log in via Firefox (for now), as needed. If they cut that off, too, I'll just have to fully abandon Google, because I'm not installing Chrome on my home PC.
