Chrome generates a column "name" in the CSV exported data, next to url, username and password. Unlike the other 3, "name" does not have a clear purpose.

According to the design doc, it is used by 1Password. Excluding it would result in a bit chaotic listing in 1Password (all names empty). Therefore Chrome currently fills it with the origin URL.

However, this seems a bit arbitrary, and other password managers might need other such columns. To keep things simple, we might consider leaving the "name" field and let the user edit the CSV as needed in some spreadsheet application.
