Access will insert an ID field—the Key field—in the table:

The key field

When the alert window popped up, and you clicked the Yes button,
Access added the ID field to the table.

The ID field is now the table’s primary key, or key field. That means it
can’t contain any duplicates.

Every table should have a key field.

For example, if a hospital keeps a database, each patient can have a
unique ID number in the key field.

That way, if it has more than one patient named John Baker, it can
easily distinguish John Baker, ID #326 in for a checkup, from John
Baker, ID #298 who needs his gall bladder removed.
