Would 2FA (let's say FreeOTP) work on Tor given the demands for privacy? Can I implement a 2FA solution on a onion website without giving away the servers location in any way along with the users on that website being able to use 2FA to access their accounts while at the same time nobody can discover where they are located?
As far I undertand you can run the authenticator from your phone without being connected to the internet however is there something that could compromise the servers or clients location if the server was seized?
I am basically looking for an anonymous 2FA solution that won't leak anyones location. Any help much appreciated.
