How do I add a Bank of America authorized user?

Yes, an authorized user can affect the primary accountholder's credit score if the authorized user is able to charge purchases to the account, either with their own card or because they know the account number.

Simply adding an authorized user to an account will not have an impact on your credit score, as the owner of the account. If, for example, the authorized user has a lower credit score than you, it won't hurt your credit score by association or anything like that. But if the authorized user racks up a bigger balance than you were planning on, it could hurt your credit score by increasing your credit utilization. Expensive debt also increases the likelihood of missed payments, which would hurt your score, too.… read full answer

So, the bottom line is that an authorized user can indirectly cause some credit score damage, but not if they don't have spending privileges.

Yes, authorized users do build credit. You can actually build a good or excellent credit score just as an authorized user on a credit card. When you become an authorized user, the account is added to your credit report, which means on-time payments by the primary cardholder will help you build good credit history. But because authorized users are not responsible for paying the bills, credit scores don’t give authorized user accounts as much weight. So you won’t build credit as fast as an authorized as you would with your own credit card account.… read full answer

Still, the fact that most credit card companies don’t have a minimum age for authorized users, means becoming one is a great way to build credit before you can get your own account. But there are a few positives and negatives you should know about before becoming an authorized user.

Here’s how authorized users build credit:

1. A friend or family member adds you to their credit card account as an authorized user.
2. The credit card account gets added to your credit reports, just like if it were your own account.
3. The issuer gives updated account information to the credit bureaus on a monthly basis.
4. Your credit standing improves if the account owner has on-time payments, low credit utilization and other signs of financial responsibility.
5. Your credit gets hurt if the account holder behaves irresponsibly.
6. You can get an account with negative information removed from your report, since you aren’t responsible for making payments.

Authorized users do build credit, but that credit can be good or bad, depending on how the primary accountholder manages balances and bill payments. So you only want to become an authorized user on an account owned by someone responsible.

But in the event that an authorized user account does end up hurting your credit, you can dispute the account to get it removed from your credit report. That’s because any mistakes made won’t be your responsibility.

Finally, you’ll build credit faster if you also have your own credit card account that you use responsibly. You can get a starter credit card once you turn 18 years old, as long as you have enough money to pay the bills.

If you have bad credit and are worried you won’t get approved, try applying for a secured credit card. Secured cards require security deposits, but they have the highest approval odds of all credit cards and accept people with bad credit.
