I created a paper backup for my offline Armory wallet. Then, I created a watching only wallet for the offline wallet and loaded the watching only wallet onto a computer connected to the Internet. Next, I deleted the offline wallet completely and restored it from the paper backup.

Question 1: Do I need to create a new watching only wallet or will the existing one work just fine with the restored offline wallet?

Question 2: If my paper backup gets stolen, can the thief use the paper backup to steal my bitcoins? If yes, if there any way to add another password on top of the paper backup in case the paper backup gets stolen? I would want the password to be something that I can remember without writing it down anywhere.

Thanks for you help in advance.

Best regards,
Allan
