Being an authorized user can raise your score or drag it down. Learn when it helps, when you could owe money, and how…
Quick answer: An authorized user can gain from the primary cardholder's on-time payments, low balance and long history, if the issuer reports the account. Late payments or high balances can hurt you. Usually the authorized user does not legally owe the debt, though some state rules, like community property, can change that.↗ Share on X

Being an authorized user on someone else's credit card can help your credit score if the account has a long history, low balance and on-time payments, and if the card company reports authorized users to the credit bureaus. It can also hurt your score if the main cardholder pays late or carries a high balance. In most cases in the U.S., the authorized user is not legally responsible for paying the debt: the primary cardholder is. But "not responsible" does not mean "no risk," and there are a few exceptions you need to know about.

This article explains how it works, when it helps, when it hurts, and how to protect yourself on both sides.

What is an authorized user, exactly?

An authorized user is a person who gets a card linked to someone else's credit card account. The authorized user can make purchases, but the account belongs to the primary cardholder. The primary cardholder applied for the card, agreed to the contract, and owes the bill.

Common examples:

This is different from a joint account holder. A joint holder applies together with the main person and is equally responsible for the full balance. Many large card companies no longer offer joint credit card accounts, so check what you are actually signing up for.

If the card company reports the account in your name, it can show up on your credit report like one of your own cards. Then it can affect your score through the same factors as any account:

Credit factorHow the shared card can helpHow it can hurt
Payment historyYears of on-time payments appear on your reportLate payments by the primary holder can appear too
Credit utilization (how much of your limit you use)A high limit with a low balance lowers your overall usageA card near its limit raises your usage
Length of credit historyAn old account can raise the average age of your accountsA brand-new account adds little
Credit mix and new creditUsually small effectUsually small effect

Two important points:

1. Not every card company reports authorized users to all three bureaus (Equifax, Experian and TransUnion). Before you rely on this, call the issuer and ask: "Do you report authorized users, and to which bureaus?"

2. Different scoring models treat authorized user accounts differently. Some lenders also look closely at authorized user accounts when you apply for a mortgage or large loan, and may give them less weight than accounts in your own name.

So being added can help, but think of it as a starting boost, not a substitute for building your own credit.

In general, no. The primary cardholder signed the credit agreement, so the card company collects from them. As an authorized user, you usually cannot be sued by the card company for the balance, and the debt is not yours to repay under the contract.

But watch for these exceptions and gray areas:

Rules vary by state and situation. If a large debt is involved, a divorce, or the death of a cardholder, talk to a licensed attorney or a nonprofit credit counselor before you act.

When does becoming an authorized user make sense?

It tends to work well when all of these are true:

1. The primary cardholder has paid on time for years.

2. The card usually has a low balance compared with its limit. Many people use under 30% of the limit as a rough rule of thumb, and lower is generally better.

3. The account is old, ideally older than most of your own accounts.

4. The issuer reports authorized users to the credit bureaus.

5. You trust each other and agree on how the card will (or will not) be used.

It is risky when the primary holder often pays late, keeps the card near its limit, or is going through money problems. In that case, their trouble can show up on your report.

How do you protect yourself as an authorized user?

1. Check your credit reports a few weeks after being added. You can get free reports from the official site, AnnualCreditReport.com. Make sure the account appears and looks correct.

2. Ask to see the account status from time to time. A quick monthly check-in can catch late payments early.

3. You do not have to use the card. You can get the credit history benefit without spending a dollar. Some people keep the card in a drawer, or never receive a physical card at all.

4. Know how to get removed. If the account starts going bad, call the card issuer and ask to be taken off as an authorized user. You can usually do this yourself. Then check your reports again; you can ask the credit bureaus to remove the account from your report if it still shows.

5. Build credit in your own name too. A secured card or a small credit-builder loan, paid on time, gives you history that no one else controls.

How does the primary cardholder protect themselves?

Adding someone is an act of trust, and the primary holder carries all the risk for the money. Before adding anyone:

1. Set a spending limit if the issuer allows it. Many card apps let you set a monthly limit for authorized users.

2. Turn on alerts for every purchase made on the authorized user's card.

3. Agree in writing, even informally, on what the card is for: emergencies only, gas only, nothing at all.

4. Remember you can remove them at any time by calling the issuer or using the app.

5. Keep paying on time and keep the balance low. Your habits now affect two credit reports, not one.

Quick comparison: authorized user, joint holder, co-signer

RoleCan use the card or loan?Legally owes the debt?Shows on credit report?
Authorized userYesUsually noOften, if the issuer reports it
Joint account holderYesYes, fullyYes
Co-signer (on loans)Usually noYes, if the borrower doesn't payYes

If someone asks you to "help with your credit" and the paperwork says joint holder or co-signer, you are taking on the debt. Read before you sign.

When should you get professional help?

If you are being contacted about debt from a card you did not open, if a spouse or parent has died and left card debt, or if you are going through a divorce with shared cards, get advice before paying anything. A licensed attorney can explain the rules in your state. A nonprofit credit counselor can help you understand your report and plan next steps, often at low or no cost.

Your next step

If you are already an authorized user, get your free credit reports from AnnualCreditReport.com today and look for the shared account. Check that it shows on-time payments and a low balance. If it shows late payments or a high balance, talk to the primary cardholder this week, and if things do not improve, call the card issuer and ask to be removed.

FAQ

Does being an authorized user build credit?

It can, if the card company reports authorized users to the credit bureaus and the account has on-time payments and a low balance. Ask the issuer which bureaus they report to.

Do authorized users have to pay the credit card debt?

Usually no. The primary cardholder owes the debt. Exceptions can apply, for example for spouses in community property states. Get legal advice if a large debt is involved.

How do I remove myself as an authorized user?

Call the card issuer and ask to be removed. Then check your credit reports and ask the bureaus to remove the account if it still appears.
