Explain in the form of a video, a blogpost or Github document how near login works, how the authorization keys are generated, and how you can manage their backup and restore properly. Show in the guide the proof that you were able to run near shell on a different machine, without authorizing a new key. Contributions in other languages are encouraged, but considered on a case by case basis. Updates to this guide, reflecting any updates of the tools involved, will be paid a % of the initial bounty per each revision, up to once per month, until Stake Wars is over.
