The authorized-user head start
If your credit card is in good standing, you can add a family member as an authorized user. Your account's history — its age, limit, and on-time payments — can appear on their credit file, giving someone with little or no history a real boost, often without them ever using the card.
It's one of the most powerful tools for parents helping a teen, or for someone helping a newcomer spouse or relative start a file.
Do it safely
Only add someone to a card you always pay on time and keep well below its limit — your habits become their history, good or bad. Confirm your issuer reports authorized users to the bureaus (most do, but ask). You can set a spending limit or simply not give them the physical card.
You stay responsible for the balance, so only add people you trust, and keep the account healthy.
When cosigning is different
Cosigning a loan or card is not the same as adding an authorized user — a cosigner is fully, legally responsible for the debt, and a missed payment hurts both people. Help as an authorized user first; only cosign if you can comfortably pay the whole thing yourself.
For many families, authorized-user status gives most of the benefit with far less risk.
Build their own file too
An authorized-user boost is a head start, not a finish line. Help them open their own secured card or credit-builder loan so they build independent history that stays with them even if they're later removed from your account.
