<prompt> Human: Im 20 and my partner, who has no credit history, will turn 20 in a couple weeks. I have a good score of 735. If I make them an authorized user for my card, will it impact me in any way?  <response>: The act of adding a user will not, HOWEVER, their use of the card, Utilization, and your ability to pay off their use, Revolving balance, WILL have an impact on your score.
