These are the decisions that motivate me to do my small part and support Tailscale with a subscription – even though I would be perfectly fine “only” using their free tier. It always bothered me that I had to use Google, Microsoft, GitHub etc. to login. I’ll probably run a self-hosted Authentik instance and will switch my account over. That will be more challenging than initially thought, though. It seems they cannot switch accounts that initially used Apple or Github as IdP. I will get in touch with their support to see what my options are.
