Are you saying you are an authorized user (not sure what you mean by “secondary”)? If you were an authorized user, all you need do is call the credit card issuer and ask to be removed from the card. If you mean you were a joint user or co-signer, then you may be responsible for the debt. If you were an authorized user and have yourself removed from the account, your credit score should return to its earlier levels.
When you sign up for your free Credit.com account, you get your credit report card that tells you how you’re doing in the major areas of your credit score. Your Vantage score, like your FICO score, is a joint venture of the big three credit bureaus—Experian, Equifax and TransUnion. The Vantage and FICO scoring models are the scores that most lenders use to evaluate you when you apply for a new credit card, a mortgage, and other types of accounts.
Your credit score uses data on how you’ve handled debt in the past to predict your likelihood of repaying a future loan or credit card balance. The higher your score, the better you look to potential creditors. Your score affects whether you get approved for credit and sometimes the interest rate or other charges you’ll pay.

Gerri Detweiler, education director for Nav, which helps business owners manage credit, says, "In this day and age, with so many reports of data breaches and identity thefts, if you aren't checking your credit, you're neglecting one of the key parts of your financial profile. You're almost opening yourself up for potential problems if you don't check, such as identity theft or mistakes that can end up being very expensive."
Each credit bureau calculates your scores differently. Experian uses the FICO Score 8, which ranges from 300 to 850. Equifax calculates your credit score on a range from 280-850 while TransUnion, rather than using a FICO model, uses the VantageScore 3.0 which also ranges from 300-850. The higher your score, the better offers and interest rates you’re eligible for.
Simply put, paying the minimum each month could cost you a lot of money and take forever to pay off. Say you have a credit card with a $1,000 balance and a 14.95 percent interest rate. According to Credit Karma’s debt repayment calculator, if you only paid $25 a month, it could cost you an estimated $393 in interest and take you an astonishing 56 months to pay off.
