What to do when a computer access is lost? (Update README.md)

Hi, I wonder what happens when I lose access to the computer (it gets broken or I leave it in some other place)? Can I somehow restore this agent state on another computer and still use this app to generate auth codes? For example, to copy some generated files to the backup device (like USB) and then on a new computer install this app and past these files to some location?
If this is possible, I propose to update REDAME file to mention this.

Thank you a lot.
