The authorized user strategy

Adding your kid (or partner, or younger sibling) as an authorized user on your credit card gives them the benefit of that card's entire history on their credit report — age, limit, perfect payment history. If you have a decade-old card with a pristine record, a brand-new 18-year-old authorized user can instantly inherit a credit score in the 700s. This is legal, widely used, and one of the best gifts a parent can give a young adult.

How it actually works

When you add someone as an authorized user, most issuers report the account to the credit bureaus under both names. The account age, credit limit, and payment history all flow through to the authorized user's credit report. For someone with no credit history at all, this is transformative — their new credit file arrives pre-populated with years of data.

What to look for in the host card

• At least 2+ years of history. The older, the better.
• Perfect payment record. A single missed payment can hurt the authorized user.
• Low utilization (below 30%, ideally below 10%). High utilization on the host card hurts the authorized user.
• An issuer that reports authorized users to all three credit bureaus. Most do, but verify — some small issuers don't.

Removing the authorized user

When the authorized user no longer needs the boost (after they've built their own credit history), remove them from the card. Most issuers will stop reporting the account on their credit file, and any benefit gradually diminishes. The experience, however, of having built real credit history from it persists — their own newly-opened accounts will continue building independently.
