For OSP Bid Packages, if the database from which the Bid was exported required logins, the Bid is not imported into any existing database. On-Screen Takeoff creates a new database set to "Login Required" but for which no Employees exist. You will need to add at least one employee with Administrator Access Level to adjust "Logins Required" although the database will allow you to open it without a login.
For OST Takeoff Files exported from a database that required logins, there is no security included in the file and it imports into any database.
