If you are currently a member of the Syncthing organization on GitHub, please enable 2FA. If you do not, you will be kicked out from the organization at some point in the future.
This is not because I say so, but because we will enable GitHub “Sponsors” for Syncthing, and to do so the org must have 2FA enforced. Enabling that setting kicks out anyone without 2FA configured. So now is a good time to beef up your security.
