<prompt> Human: Im 19 years old and currently attending a CC and was looking for starter credit cards to start building my credit score. I read that I should first make a credit karma account just to make sure if I do or dont have a credit score. Well I made the account and found out that I have a I have 772 credit score. Basically my parents made me an authorized user on their credit card about about 1.5 year ago and have been building my credit for me. I use the credit card all the time but I never thought that it was my own credit card. Im really grateful to them for it because they know how important credit score is in the adult world. My question is: Should I still look for a new credit card under my own name or should I continue being an authorized user under my parents? Edit: Thank you guys for all your advice! Im going to remain an authorized user under my parents credit card. Ill also be getting my own credit card as well. I read every single comment and appreciate all the advice!  <response>: Having another card will also increase your available credit, which will also positively impact your credit score. The scores also look at how much of your credit you use, so having a higher total amount of credit available to you is a positive in more than one way. I find that having more than one card is helpful if one of them is declineddoesnt work, or if I need to freeze one. As long as you keep the balances low and pay them off before accruing interest, having a few credit cards available is a good thing.
