Hey, that's how I started getting credit. I opened a checking account when I was 16 which feels like 100 years ago now, made a deposit and got a secured, MasterCard. When I proved that I could handle using it properly, they issued me a higher credit limit than what was deposited.
No one just gives credit. It has to be earned. I wasn't tryuing to rag on the poster, but if he/she read any of the threads on this board, they would know that no one is going to give up their login info.
