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.

Before 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.

These 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.

If 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.

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
