Becoming an Authorized User to Build Credit
How it builds credit
When you are added as an authorized user (AU) on someone else card, that account often appears on your credit report with its full history: its age, limit, and payment record. For someone with a thin or new file, inheriting a long, clean account can raise your score quickly, which is why parents often add children to help them start. See authorized users explained for the basics.
When it actually helps
Three conditions matter: the issuer must report AUs to the credit bureaus (most major ones do, but confirm), the account should be old and have a low balance relative to its limit, and the primary must pay on time. An old, pristine card helps a lot; a maxed-out or newer card helps little or could hurt.
The risks
It cuts both ways: if the primary runs up the balance or misses payments, that can land on your report too. You also do not own the account, so the primary can remove you anytime. Treat it as a kickstart for a thin file, not a long-term strategy, and pair it with your own secured card or starter card. See how to build credit.
