<prompt> Human: My wifes credit is near perfect, and as weve just been married, Ill be added as an authorized user to her cards, but my score sucks. Will this addition to my CBR help increase my FICO score? Also, so long as I dont jeopardize her credit, will my being added with a lower FICO screw up her score at all?  <response>: Different models vary on whether authorized users count for credit scores. They typically do though, so it should help you. Adding you to her card shouldnt affect her scores, unless of course you buy all kinds of crap and you guys miss CC payments. not likely, im assuming.
