I have a Netbird account I have tested and used to remotely access my network, and I plan to keep that account restricted to just me. Netbird has a free tier that’s limited to 5 users/accounts and 100 peers (devices). I recently set up a Minecraft server on my Proxmox so I can play with a group of friends, but I obviously need more than just 4 accounts. Has anyone ever made a second account to share with multiple people? If you did, did you have MFA also turned on?


They have Open Source versions of their stack. Just run it yourself at no cost.
Am I missing something?
Also, use any other similar service which all have open source counterparts: Head scale/Tailscale, or ZeroTier.
