Is there a way to link a person to a unique ID and the unique ID

Is there a way to link a person to a unique ID and the unique ID is associated and used for that person every time the person logs in?

Hi,

You can try the spreadsheet widget. The user just needs to type the Unique code/ID and it will auto-populate the form fields from the spreadsheet. Please try it and let us know if you need further help. Thank you!
