I had a heart attack when I saw that passwords were leaked from other private servers, because honestly, I use the same password for everything. I use two step authentication on everything that matters to me, and I would say this matters A LOT. A lot of time put into this server and I would be really sad if somehow my email was compromised and changed, making it even harder to recover my account. Microsoft authentication app is a pretty good program to use, not sure how hard it is to implement it, but I would appreciate it a lot if someone could make this happen.
