Hello, hi and cheers to your Saturday, friend. I hope you’re someplace warm and cozy. Today’s brain-enhancing trivia is about our U.S. nuclear weapons system. Which of the following does it use: A.) Quantum computing technology, B.) 8-inch floppy disks or C.) Artificial intelligence? You’ll find the answer at the end.

When you live with someone, you make a heck of a lot of choices together — big choices, like, “Should we sell our house and move to Thailand?” and small choices, like, “Should we buy this new recycling bin?”

Somewhere in the middle is an important, often infuriating step: “Whose email address should we use to log into Netflix?”

The solution: A joint email account for shared services

The “where” is up to you. If you’re both Gmail people, great — use that. If you use different email platforms, flip a coin.

Some email platforms, including Gmail, have options for an easy “Shared Account.” Name it something obvious, like, “LucyAndRickyRicardo,” or you can even use an inside joke.

Keep this account strictly for stuff you both want to receive, control and manage. Anything you’re splitting payments on qualifies, along with bank accounts, school contact info, utilities, the mortgage, and other accounts where both of you want access to the login and notifications.

Keep your stuff just yours

Of course, both of you should have a personal email address for the newsletters you love (like this one!), messages from old friends and professional emails, for instance. But this is also the perfect email for logins that only interest you.

Ricky may want to use his email to order pork for Cuban sandwiches and sign into a forum that discusses the best conga drums. Lucy might want to use her email to play bridge online and place orders for Vitameatavegamin.

Use throwaway email accounts to lighten the load

Clear up the clutter and confusion by using a “disposable” email designed to fade into the void. Top options include Temp Mail, SimpleLogin and Burner Mail.

Both of you can use this service to sign up for accounts you don’t intend to keep — free trials you don’t mind expiring, sign-ups for a one-time purchase, blogs that might send you spam mail, whatever.

Add a password manager everyone can use

If you’re together for the long haul, I highly recommend you pick out a password manager to keep your shared logins saved, organized and auto-filled. Password managers can come up with new, safe passwords on demand, which means you’ll never be texting to get the power company website password again.

Whether you’re catching up on Lucy’s job at the candy factory (wasn’t that the funniest skit?) or choosing who manages home insurance, you’ve got an email login structure that works for everyone.

A little Lucille Ball wisdom to leave you with: “A man who correctly guesses a woman’s age may be smart, but he’s not very bright.”

👂🏼 Is Facebook listening through your phone’s mic? Consumer Reports says no, but what’s happening is still creepy. Facebook gets our personal data from nearly 48,000 companies. Data brokers like LiveRamp, along with big retailers and even small shops, are in on it. So, myth busted. It doesn’t need to listen.

No more pretending: Google just made a subtle and important update to Chrome’s Incognito warning. Why? A lawsuit, of course. Switch to an Incognito tab and you’ll see “Browse more privately,” not just “Browse privately.” Yes, Google and others can still track you. For true privacy, you need a VPN. FYI, this link gives you an extra three months of ExpressVPN.

AI-mazon to the rescue: Amazon has a new AI chatbot you can find in the iOS or Android app. Need to know a shelf’s size? Sure. But how about a poem to go with the heartfelt gift for your spouse? Not everyone has access yet. Look for it right in the “Questions?” box on a product page.

🎮 Cheaters, beware! Call of Duty’s Ricochet anti-cheat now shuts down the game if it catches you using aim assist with a mouse and keyboard. This affects all current titles, including Modern Warfare III, Modern Warfare II and Warzone.

💸 Bezos is ballin’: Jeff Bezos made $7.9 million per hour last year. No, not from paychecks. The mega-rich, like Bezos, Musk and Michael Jordan, rake in the dough through business and property, not their salaries. Want to join the billionaire club? Owners are the ones most likely to make bank. A trust fund and some luck wouldn’t hurt, either.

Back in business: Apple just disabled the blood oxygen monitor on its Series 9 ($399) and Ultra 2 ($799) watches. They’re currently fighting over patent rights with a company called Masimo, so this means they can sidestep a U.S. sales ban. Shocker: Despite yanking a “lifesaving” feature, there’s no change in price.

Vroom-vroom! Color-changing paint and automatic parallel parking? Yeah, I want a car of the future.

Forget the cloud! Our data is going all the way to the moon.

Error 404: Property doesn’t exist: Don’t let scammers ruin your vacation before it starts. Know how to spot a fake rental.

No, you didn’t miss a delivery. It’s a spam text. Some are sneaky, so refresh yourself on the red flags.

Free money! I put together a list of class-action lawsuits paying out soon if you make a claim.

Help is on the way: Cheap security cameras that just record are OK, but you deserve more. SimpliSafe’s Fast Protect includes 24/7 police, fire and medical dispatch, along with backup coverage if the power goes out, security alerts and unlimited recording. Use my link for 20% off a new system, and get a free indoor camera with Fast Protect Monitoring.

🚗 Classic car junkies, listen up: You can browse vintage cars through the Bring a Trailer Auctions app. Sift through auctions, keep tabs on sales and filter searches by model more efficiently on your phone. Sorry, Android fans — it’s only on iOS right now.

Leave me be: Your phone can track steps, but some readers and listeners have told me they want to know their distance without carrying a phone all day. This basic pedometer has a battery that’ll last about a year and is small enough to clip onto your pocket.

Hide-and-seek: You’re shopping online for your honey’s Valentine’s Day present and they stroll into the room. Quick! Hide your open windows. On a PC: Windows key + M. (Use Windows key + Shift + M to reopen.) On a Mac: Cmd + Option + H + M. Ahem, yes — this works no matter what’s on the screen.

🔄 Undo mistakes: Get out of the menu and use your keyboard! Type Ctrl + Z (Windows) or Cmd + Z (Mac) to undo your last action in various applications — typing, deleting or formatting.

No kidding, I used to be a Boy Scout leader. (It’s a long story.) No wonder I’m always prepared! I have a backup generator at home, so I’m never worried when the power goes out for everyone else in the neighborhood.

So, you can use a backup generator to power your:

• Fridge: Keep your food safe
• Microwave: Warm up a meal
• CPAP: Sleep better at night
• Medical devices: Survive the storm
• Phones: Call family and friends
• Computers and tablets: Get work done
• Lights: Remain calm in a crisis
• TV: Stay connected and alert
• Heat and AC: Stay warm or cool
• Security lights: Scare off looters
• RV and tailgating: Griddles, speakers and more

The American-made Patriot Power Generator 2000X is so popular that the first launch sold out immediately. Don’t miss this opportunity.

The answer: B.) 8-inch floppy disks. The U.S. nuclear weapons system and the U.S. Air Force’s nuclear missile silos still rely on 1970s-era IBM computers that use the disks. According to reps at the Pentagon, “This system remains in use because, in short, it still works.” And it’s not as hackable as today’s systems.

🍑 From Allison in Texas: “I would love a Kim Komando fanny pack. Where can I buy one?” You can buy one in my Etsy store, along with other merch like hats, shirts and an AirPods case cover.

If you learned something, smiled or slapped your forehead over one of my jokes, hit the thumbs-up at the end. I’ll see you tomorrow with another exciting issue of the best newsletter in the USA! — Kim
