  • To increase the security of the safebox, would be better if we split the step of interacting with it (insert and get items) into two
    • Open the safebox (with a valid id and password) to get a token
    • Use this token lately to add or obtain items, sending it through an HTTP Header
  • The token will be valid for the next 3 minutes
  • The system will block the safebox after 3 failed opening attempts (considering a failing attempt as a wrong combination between safebox id and password). Don't worry about unblocking it, we don't care about that it nowadays
