<prompt> Human: Neither my boyfriend or I have debt. He wants to get into a field and discovered that one factor they consider is your credit score. The career doesnt pertain to finance. He has only had a credit card for less than a year and has rarely purchased anything on it, and only has 1000 of credit available to him. His credit score is something like 520-530. I think hes paid his bills on time but the problem is he hasnt had an established history.My credit score is 740. Not amazing but pretty good IMO.He wants to immediately boost his credit score, but it seems most things in the short term wont improve the situation - its more of a long term thing.Hes not that good with money, which concerns me. Can I add him as an authorized user and just not give him the card to improve his score? Itll essentially be my credit card with his name on it? How long would it take for his credit score to increase a bit with this strategy, assuming I managed it as if were my own card?Weve been together for years, so I trust him on a personal level to not be up to anything nefarious, but I dont trust his budgeting abilities and the like.Further, would it damage my credit score in any way?Assistant: Can he ask his parents? My parents did it for me, they offered as soon as they could. Human: No, his parents are weird. High income, but they have a lot of debt. They couldnt help.  <response>: If his credit needs improving and there is a family history of not been financially responsible, I would not tangle my credit history with someone elses. It only takes a moment to lose your good credit and a long time to fix it.
