Adding Authorized Users: The Full Picture
If you've got a credit card you love, the next instinct is often to add your spouse or your keiki to it as authorized users. The thinking goes: more people using the card = more rewards earned, & it's an easy way to share the benefits.
In my Ohana Program, the math usually doesn't work out that way. Here's the full picture.
What an Authorized User Account Actually Is
An authorized user (AU) account is when you add someone to your existing credit card so they get a card with their name on it - but the actual account belongs to you. The AU isn't legally responsible for the bill. You are.
When you add someone as an AU, here's what typically happens:
They get a physical card with their name on it
The account often shows up on their personal credit report
Their spending earns rewards in YOUR account (not theirs)
You stay liable for any balance
The third point is the kicker. Adding your spouse as an AU doesn't help them earn their own welcome bonuses, build their own card history, or contribute to their own 5/24 strategy. It just routes their spending through your account.
Why Adding AUs Rarely Pays Off
The whole engine of the points strategy is welcome bonuses. A welcome bonus card in your wallet earns 10x-20x points per dollar instead of 1x. Without one, you're losing the leverage.
When you add a spouse as an AU on YOUR card, they're spending on YOUR welcome bonus - which you'd hit anyway. They're not opening cards in their own name & earning their own welcome bonuses, which is where the real household strategy unlocks.
The math: when each spouse opens their own cards & earns their own welcome bonuses, a household's rewards points can roughly double compared to running everything through one cardholder's account with the other as AU. The AU setup leaves real value on the table.
When AUs DO Help: The Credit-Building Case
There's one situation where adding an AU genuinely makes sense: helping someone establish or rebuild their personal credit.
A young adult with no credit history, or someone rebuilding from past damage, can pick up years of payment history & account age by being added as an AU on a well-managed card. Their credit score can improve meaningfully over time without them needing to open accounts on their own.
For someone in that situation, the credit-building benefit usually outweighs the strategic cost - because they're not yet ready to be opening rewards cards anyway. Their first job is getting their credit healthy enough to qualify when the time comes.
If you're considering adding a kid, a young adult relative, or anyone else who could use the credit boost, that's a real & valid reason. Just lmk so I can factor it into your strategy.
How to Share the Card Without Adding an AU
This is the natural follow-up question. If you don't add your spouse as an AU, how do they actually use the card for day-to-day purchases?
Two simple workarounds cover almost everything:
Load the card into their eWallet. Apple Pay, Google Pay, Samsung Pay - all of 'em. The named cardholder shares the card details, the spouse loads it into their phone, & they tap-tap-tap their way through in-person purchases like it's their own.
For online purchases, just use the card number. Type in the number, expiration, & security code at checkout. The website doesn't care who's typing.
Between those two approaches, almost every household covers daily spending without ever needing an AU. Your spouse uses "your" card for groceries, gas, online shopping - everything - all without being on the account.
What About the 5/24 Angle?
If you've already got AU accounts on your credit report, those usually count toward your 5/24 number even though you didn't open them. That can quietly use up your personal slots.
If your AU accounts are bumping you near or over 5/24, there are typically two options - wait for them to age out, or have the primary cardholder remove you. The full mechanics live on a separate page.
What I Usually Recommend
For most households I work with: don't add AUs. Each adult should be opening their own cards & earning their own welcome bonuses. The only consistent exception is the credit-building case described above.
You probably let me know all of your AU accounts during our card-list intake. Lmk if there's any you think you may have forgotten - I'll factor them into your 5/24 math.
