I am trying to figure out a plan as a preventive measure of what I can do to protect my assets if my github account is hijacked. I have been the target of a series of attacks of which the attacker now has access to all of my online accounts, passwords, computer, & cell phone. They also happen to live below me and because of the close proximity they are able to surveill everything in my house using SDR transceivers, including all keystrokes and everything I write down. I am now in a position where I am at risk of having my github account hijacked. I have been in contact with github support about what I can do to associate my personal information to my github account, so that I am able to recover a hijacked account in the event this takes place, however I was told that they do not offer anything that would allow me to tie my personal information to a personal account.
Are there any measures I can do to allow myself to recover my github account in the event that it is hijcked. Does an enterprise account offer further security protection that would mitigate this? Or is there anything else I can do to prevent this/mitigate this if it happens?
