How does becoming an authorized user affect your credit?
When you are added as an authorized user on someone's credit card, that account's history can appear on your report: its age, limit, and payment record, good or bad. A long, clean, low-utilization account can help your file; a maxed-out or delinquent one imports its problems. You aren't liable for the debt, and after removal most bureaus drop the tradeline.
How the mechanism works
An authorized user (AU) gets a card on someone else's account with no liability for the balance. Most major issuers report AU accounts to the bureaus, so the account's full profile (open date, credit limit, balance, payment history) lands on your report and gets read by scoring models. This is why adding a young adult to a parent's old, clean card is the classic credit-building move: it imports years of positive history onto a thin file.
When it helps and when it hurts
- Helps: the account is old, has a high limit with low utilization, and a spotless payment record.
- Hurts: the account carries high balances (its utilization blends into your file's picture) or develops late payments, which land on your report too.
- Does little: some issuers don't report AU accounts, and some newer scoring treatments discount AU tradelines, so the boost varies.
Getting off an account that hurts you
You can be removed as an authorized user at any time; either the primary cardholder or usually you yourself can call the issuer and request it. After removal, the issuer stops reporting the account under your name, and the bureaus generally drop the AU tradeline from your report in the following cycles. If an AU account you were removed from keeps reporting, or one appears that you never agreed to, both are disputable.
One caution on rented tradelines
Paying a stranger to add you as an AU ('tradeline rental') exists as an industry, and it is a bad idea: lenders treat it as misrepresentation, newer models discount it, and it puts your file's credibility at risk. The legitimate version of this strategy involves family or someone who actually trusts you with their account.

Credit utilization is how much of your available revolving credit you're using — your balances divided by your credit limits. It's one of the biggest factors in your score, usually second only to payment history. Lower is better: many lenders look for under 30%, and under 10% is ideal. High utilization can drop your score fast, but it's also one of the quickest things to fix.
The standard FICO credit score is built from five factors: payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new credit (10%). Payment history and utilization together account for two-thirds of the score, which is why disputing inaccurate late payments and incorrect balances tends to move scores the most.
You can dispute any item on your credit report that's inaccurate, incomplete, outdated, or unverifiable — including wrong balances, payments marked late incorrectly, accounts that aren't yours, items past the 7-year window, and reporting that violates the FCRA. You cannot dispute debts you legitimately owe and that are reported accurately. CreditRefresh won't generate letters without grounds.
