An authorized user is someone added to another person's credit card account, able to make purchases without being legally responsible for the debt. Most major issuers report the account's full history to the authorized user's credit file — including its age, which can make this one of the fastest ways to build a credit history.
The upside
If the primary cardholder has a long-standing account with low utilization and a perfect payment record, that entire history can appear on your report almost immediately. This is why parents commonly add adult children as authorized users to help them establish credit before they've opened any accounts of their own.
Their mistakes become your mistakes
Questions to ask before agreeing
- Does the issuer report authorized user activity to the credit bureaus? (Not all do.)
- What's the account's current utilization and payment history?
- How long has the account been open?
- Will I actually receive a physical or virtual card, or just be added to the account?
