Generally, if you receive a message that asks for a password, that means that you installed Kronocard on another computer. If this is right, it's ok. Because Kronocard is not a "cloud" software if you install it on one computer, scan some cards, list online and need to change to another computer, it will not synchronize the data. You need to copy the data from the first computer to the second one like you will do with any other documents or photos. If you need to move your data from one computer to the other one here is the procedure.
If you have never listed cards for sale online on kronozio.com or eBay or asked for documentation, you can enter the password, and it will activate Kronocard on that new computer.
That password is dynamic; it changes every day. It's a combination of the three letters kds+the last two digits of the year+the month number+day number. As an example if we are June 21, 2019 the password will be kds46 (19 + 6 + 21 = 46)
