The gnome-authenticator has this functionality, i propose adding this for the sake of feature parity, the gnome software exports/imports data in JSON format, i suggest using the same data structure for ease of migrating between gnome and kde Example data (FAKE SECRET KEYS): [ { "secret": "DW6UXL48SDKFNZ66", "label": "user_name", "period": 30, "digits": 6, "type": "OTP", "algorithm": "SHA1", "thumbnail": "Default", "last_used": 0, "tags": [ "google.com" ] }, { "secret": "0UNGLXHQYMH8WJV6", "label": "pqwoerituytrueiwoq", "period": 30, "digits": 6, "type": "OTP", "algorithm": "SHA1", "thumbnail": "Default", "last_used": 0, "tags": [ "kde.org" ] } ]
As for the time being I was also looking for a solution, I found that copying the /home/[username]/.config/org.kde.keysmith/ does the trick. It's a workaround until we get a proper implementation into the GUI.
