SSO is great and it makes user management so much easier. I'm in the process of moving as much stuff to SSO as possible and it's super frustrating how many vendors lock it behind an "enterprise" license. For example, we would like to use a certain "spot" hub for managing our social media but to get SSO it would cost us ~$30k / year. WTF!?!?!
So, I'm happy to see that Tailscale is bucking the trend and happy to be a Tailscale customer.
