Twitter Is Ending Free SMS 2FA, but There’s a Better Option on Your iPhone
Don’t pay for Twitter Blue. Your iPhone has a two-factor authentication feature that’s more secure than text message.
Twitter announced earlier this month that it will no longer support text message two-factor authentication. As a Twitter user, the only way you can continue using SMS 2FA is if you sign up for the Twitter Blue service, which requires a monthly payment. If you’re an iPhone owner, there is a more secure 2FA alternative for Twitter that’s already built into your iPhone anyway — and it’s free to use.
According to Twitter, 74% of Twitter users with two-factor authentication enabled use the text message option. While it’s unfortunate that you’ll no longer have that available to you unless you pay, you’re better off without SMS 2FA anyway. Authentication apps such as Google Authenticator are superior because they’re more secure than the text message method — it’s easier for attackers to spoof your texts remotely, especially with SIM swapping.


And if you use an iPhone, you don’t have to download any third-party apps to get better two-factor authentication protection on your device. Apple has an authenticator hidden in your settings that you can use to help better secure your accounts and data.
Here’s how to set it up with Twitter, as well as with other apps and websites.

How to set up your iPhone’s built-in 2FA with Twitter
If you want to use your iPhone’s built-in two-factor authenticator specifically with Twitter, here’s what you need to do.
In the Twitter app, tap on your profile icon in the top-left and then go to Settings and Support > Settings and privacy > Security and and account access > Security > Two-factor authentication. If you’re asked to enter your Twitter password at any time, do so to continue.
Now, toggle on the Authentication app option, enter your account password, tap Get Started and hit the Link app button. You’ll be redirected to your saved Twitter passwords in your settings — choose the correct one for your account. Next, copy the verification code to your clipboard and enter it into Twitter. Finally, hit Confirm and your Twitter account should now be protected by your iPhone’s two-factor authenticator.


Enter your confirmation code quickly. You only have a a few seconds before a new one is generated.
Nelson Aguilar/CNETBefore you continue, make sure to write down the single-use backup code that appears. This will help you log back into Twitter if you have trouble accessing your iPhone’s two-factor authentication method. Also, you can toggle off text message 2FA now or wait until Twitter automatically disables it for you.
You can also set up iOS’s built-in 2FA with other apps and websites
For every other service that’s not Twitter, launch the Settings application on your iPhone and go into Passwords. Use Face or Touch ID to access your passwords and then tap on whatever account it is you want to set up 2FA for.
Note: This method of two-factor authentication does not work with every website or app.
Next, tap Set Up Verification Code and a menu will appear with two options:
- Enter Setup Key
- Scan QR Code


Go to Settings -> Passwords -> Set Up Verification Code to set up 2FA.
Nelson Aguilar/CNETThese are your two options to set up 2FA, which you can find on the website of whichever account you’re attempting to secure. To continue, go to the website, use your credentials to log in and then go into the website’s account settings. There is no single place where you’ll find the setup key or QR code for 2FA, but generally you should find them in «passwords» or «two-factor authentication.»
For this example, we’ll be using the setup key found in the account settings on Mega’s website. If you see a setup key, simply copy it to your clipboard, and then go back to the Settings app on your iPhone and choose the Enter Setup Key option. Next, paste in the setup key and then hit OK. Once you do, a verification code will appear.
Go back to the website you grabbed the setup key from and enter the verification code to enable 2FA. You don’t have to manually enter the setup key, as it should appear at the top of your keyboard, so you can just tap there to enter it. However, you must be quick to enter the setup key because it’ll change every 30 seconds.


If using the setup key option, paste it into Settings when prompted and then enter the verification code on the website.
Nelson Aguilar/CNETIf you use the Scan QR Code option, the process will pretty much be the same, but instead of entering the setup key manually, you’ll simply scan the QR code with your smartphone’s camera. However, this option may not be ideal if you’re doing everything on your smartphone, so really only use this if you’re accessing the website on another device.
Once you’re finished, two-factor authentication should be enabled for that website. Anytime you log in to that website in the future, you’ll be asked to enter a verification code as well, which will be generated by the built-in feature.

Stay Informed About Your Flights This Holiday Season With Your iPhone’s Tracker
Your iPhone is hiding a flight tracker. Here’s how it works.
Thanksgiving is only a few short weeks away and if you plan on flying during the holiday season, keeping up-to-date on changes to your flights is crucial. Airports can be hectic during any holiday, but with the government shutdown continuing, flights are liable to change or be cancelled more often.
Luckily, it’s never been easier to get up-to-date information about your flight. For starters, your airline probably has an app, and if not, you can check its website. If you’re in a hurry, you can Google the flight number. Or you can just use your iPhone’s built-in flight tracker that’s sneakily tucked away.
That’s right: Your iPhone has a flight tracker that you may have never known about. It’s there for when it’s needed. Below, we’ll show you have to access it in not one, but two places, so you never have to go hunting for your flight info elsewhere again.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source on Chrome.
For more on the iPhone, check out everything Apple announced at WWDC 2025.
How to track your flight via iMessage
Before we start, there are a few prerequisites you must meet:
- Make sure iMessage is enabled (it doesn’t work with SMS/MMS).
- You’ll need your flight number somewhere in your text messages, whether you’ve sent that information to someone (even yourself) or it’s been sent to you.
- The flight number must be sent in this format: [Airline] [Flight number], for example, American Airlines 9707.
Launch the native Messages app on your iPhone and open the text message thread that contains your flight information. You’ll know the flight tracker feature works when the text with the flight information appears underlined, which means it’s actionable and you can tap on it.
If your flight is still several months away or it’s already passed, you might see a message that says, «Flight information unavailable.» You might also see another flight that’s not yours because airlines recycle flight numbers.
You can check your flight status from Spotlight Search, too
If getting your flight information from Messages wasn’t easy enough, you can also grab the details right from your iPhone’s home screen by swiping down and adding your flight number into Spotlight Search. Even better, this works with Spotlight Search on your Mac computer, too.
How to access the hidden flight tracker
Although the airline name/flight number format highlighted above is the best way to go, there are other texting options that will lead you to the same result. So let’s say we stick with American Airlines 9707, other options that may bring up the flight tracker include:
- AmericanAirlines9707 (no spaces)
- AmericanAirlines 9707 (only one space)
- AA9707 (airline name is abbreviated and no space)
- AA 9707 (abbreviated and space)
I would suggest you keep the airline name spelled out completely and add a space between the two pieces of information — like in the previous section — because for some airlines, these alternative options may not work.
Real-time flight tracking
Once everything is set, tap on the flight information in your text messages. If the feature works correctly, you should see the following two options appear in a quick-action menu:
- Preview Flight: View the flight’s details. Tap this to view more information about the flight.
- Copy Flight Code: Copy the flight code to your clipboard (in case you want to send your flight details to someone else via text or email).
If you select Preview Flight, at the top of the window, you’ll see the best part of this feature: a real-time flight tracker map. A line will connect the two destinations, and a tiny airplane will move between them, indicating where the flight is at that exact moment.
Underneath the map, you’ll see important flight information:
- Airline name and flight number
- Flight status (arriving on time, delayed, canceled, etc.)
- Terminal and gate numbers (for arrival and departure)
- Arrival and departure time
- Flight duration
- Baggage claim (the number of the baggage carousel)
If you swipe left on the bottom half of the flight tracker, you can switch between flights, but only if there’s a return flight.

This $20K Humanoid Robot Promises to Tidy Your Home. But There Are Strings Attached
The new Neo robot from 1X is designed to do chores. It’ll need help from you — and from folks behind the curtain.
It stands 5 feet, 6 inches tall, weighs about as much as a golden retriever and costs near the price of a brand-new budget car.
This is Neo, the humanoid robot. It’s billed as a personal assistant you can talk to and eventually rely on to take care of everyday tasks, such as loading the dishwasher and folding laundry.
Neo doesn’t work cheap. It’ll cost you $20,000. And even then, you’ll still have to train this new home bot, and possibly need a remote assist as well.
If that sounds enticing, preorders are now open (for a mere $200 down). You’ll be signing up as an early adopter for what Neo’s maker, a California-based company called 1X, is calling a «consumer-ready humanoid.» That’s opposed to other humanoids under development from the likes of Tesla and Figure, which are, for the moment at least, more focused on factory environments.
Neo is a whole order of magnitude different from robot vacuums like those from Roomba, Eufy and Ecovacs, and embodies a long-running sci-fi fantasy of robot maids and butlers doing chores and picking up after us. If this is the future, read on for more of what’s in store.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
What the Neo robot can do around the house
The pitch from 1X is that Neo can do all manner of household chores: fold laundry, run a vacuum, tidy shelves, bring in the groceries. It can open doors, climb stairs and even act as a home entertainment system.
Neo appears to move smoothly, with a soft, almost human-like gait, thanks to 1X’s tendon-driven motor system that gives it gentle motion and impressive strength. The company says it can lift up to 154 pounds and carry 55 pounds, but it is quieter than a refrigerator. It’s covered in soft materials and neutral colors, making it look less intimidating than metallic prototypes from other companies.
The company says Neo has a 4-hour runtime. Its hands are IP68-rated, meaning they’re submersible in water. It can connect via Wi-Fi, Bluetooth and 5G. For conversation, it has a built-in LLM, the same sort of AI technology that powers ChatGPT and Gemini.
The primary way to control the Neo robot will be by speaking to it, just as if it were a person in your home.
Still, Neo’s usefulness today depends heavily on how you define useful. The Wall Street Journal’s Joanna Stern got an up-close look at Neo at 1X’s headquarters and found that, at least for now, it’s largely teleoperated, meaning a human often operates it remotely using a virtual-reality headset and controllers.
«I didn’t see Neo do anything autonomously, although the company did share a video of Neo opening a door on its own,» Stern wrote last week.
1X CEO Bernt Børnich told her that Neo will do most things autonomously in 2026, though he also acknowledged that the quality «may lag at first.»
The company’s FAQ says that for any chore request Neo doesn’t know how to accomplish, «you can schedule a 1X Expert to guide it» to help the robot «learn while getting the job done.»
What you need to know about Neo and privacy
Part of what early adopters are signing up for is to let Neo learn from their environment so that future versions can operate more independently.
That learning process raises privacy and trust questions. The robot uses a mix of visual, audio and contextual intelligence — meaning it can see, hear and remember interactions with users throughout their homes.
«If you buy this product, it is because you’re OK with that social contract,» Børnich told the Journal. «It’s less about Neo instantly doing your chores and more about you helping Neo learn to do them safely and effectively.»
Neo’s reliance on human operation behind the scenes prompted a response from John Carmack, a computer industry luminary known for his work with VR systems and the lead programmer of classic video games including Doom and Quake.
«Companies selling the dream of autonomous household humanoid robots today would be better off embracing reality and selling ‘remote operated household help’,» he wrote in a post on the X social network (formerly Twitter) on Monday.
1X says it’s taking steps to protect your privacy: Neo listens only when it recognizes it’s being addressed, and its cameras will blur out humans. You can restrict Neo from entering or viewing specific areas of your home, and the robot will never be teleoperated without owner approval, the company says.
But inviting an AI-equipped humanoid to observe your home life isn’t a small step.
The first units will ship to customers in the US in 2026. There is a $499 monthly subscription alternative to the $20,000 full-purchase price, though that will be available at an unspecified later date. A broader international rollout is promised for 2027.
Neo’s got a long road ahead of it to live up to the expectations set by Rosie the Robot in The Jetsons way back when. But this is no Hanna-Barbera cartoon. What we’re seeing now is a much more tangible harbinger of change.
