Twitter Is Done With SMS 2FA. Here’s a Better Way to Secure Your Account on iPhone

SMS two-factor authentication is no longer available on Twitter, unless you pay for Twitter Blue. Fortunately, if your an iPhone user, there’s a better option anyway.

As of today, Twitter no longer supports text message two-factor authentication as a security measure for your accounts. The only way you can continue using SMS 2FA is if you sign up for Twitter Blue — but that requires a monthly payment.

If you have an iPhone, however, there’s a more secure 2FA alternative for Twitter that’s already built into iOS. And it’s free to use.

According to Twitter, 74% of Twitter users with two-factor authentication turned on use the text message option. While it’s unfortunate that you 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.

OpenAI chief Sam Altman outlines why the AI sector is urging a slowdown: risk of losing control

Sam Altman and Dario Amodei call for a measured pace in AI development, proposing safety frameworks and international coordination to avoid losing control, while U.S. and Chinese tensions underscore the urgency.

OpenAI’s Sam Altman offered the most thorough remarks to date on potential AI safety frameworks, following his alignment with Anthropic’s Dario Amodei and Elon Musk in urging a temporary slowdown of the sector. Tensions surrounding AI safety have surged after an Anthropic researcher resigned last week, claiming that developers feared the technology could “cause humanity’s demise by the end of the decade,” a warning that spurred similar alarm among OpenAI staff and other lab members. The leaders of major AI firms have recently shown uncommon agreement, as Altman and Musk jointly endorsed Amodei’s essay calling for a measured pace in advancing the most powerful AI models. AI‑related stock prices fell on Monday as investors reacted to the statements, while U.S. President Donald Trump rejected the CEOs’ caution on Sunday, arguing that a slowdown would hinder America’s dominance in AI compared with China. Sam Altman outlines two potential disastrous outcomes for AI development. Altman stated in a late‑night X post that a federal framework establishing uniform safety standards for frontier AI is welcome, emphasizing that “no level of American competitive pressure can excuse reckless behavior.” He warned that AI advancement might lead to loss of control over future outcomes and could concentrate excessive power in the hands of a single individual or corporation. At the same time, Washington legislators are rushing to respond to demands for regulatory safeguards. The developments occur as Anthropic and OpenAI prepare for what could be historic initial public offerings, with Altman stating in a Fortune interview on Saturday that the companies will not pursue an IPO in 2026. Amodei’s three‑step plan. A primary safety concern involves models gaining the capacity to enhance their own performance, a process called recursive self‑improvement (RSI). He noted that since early summer AI has been progressing rapidly, largely because AI systems are now capable of creating the next generation of AI themselves. He warned that without oversight, the technology could outpace our capacity to comprehend and control it, making careful, possibly restrained, development essential. He outlined a three‑step approach designed to slow development while preserving commercial benefits and maintaining the United States’ competitive edge in AI. The plan calls for every frontier AI company to provide external evaluators with access comparable to that of employees — a commitment Anthropic has already made — and urges all such labs to adopt shared safety standards, curb uncontrolled AI acceleration, and coordinate globally. On Saturday, Altman posted on X that he concurred with Amodei’s call for AI firms to “pace the frontier,” adding that adopting independent evaluators with employee‑level access is a worthwhile step and that his company will follow suit. Altman said in a Monday post that consistent regulations to manage frontier risk — such as independent auditors — are valuable, but clarified that “pacing” does not equate to halting progress, which remains swift and ongoing. He concluded that the costs of pacing are justified, asserting that no level of American competitive pressure can excuse reckless actions that let capabilities outpace alignment and monitoring. He noted that governmental assistance will be needed for international coordination, but emphasized that the industry should first act independently. Coordinating AI safety measures and a sector‑wide slowdown with Chinese AI developers will present significant hurdles. The United States and China continue a rivalry for AI supremacy, with tensions rising as Chinese models become increasingly sophisticated and widely adopted. He added that the toughest aspect of his proposal is the possibility that rival nations may decline to adopt similar measures. He noted that the long‑term goal would be collaborative effort to impose a speed limit on AI progress, according to an interview with CBS News’ “Sunday Morning.” He acknowledged that achieving such a limit would be challenging due to strong incentives to get ahead and the military advantages involved, admitting uncertainty about feasibility but urging an attempt. The essay has attracted criticism in China, with state‑owned Global Times stating on Monday that “Amodei’s proposals aim to cast China’s legitimate AI development as a threat and exacerbate U.S.–China confrontation.” China’s Foreign Ministry responded on Monday, labeling the CEOs’ remarks as “fearmongering.”

Novo CEO tells CNBC why drugmaker is rebranding, needs to ‘rethink’ obesity strategy

The Danish drugmaker called the changes the beginning of a new chapter for the company, which faces stiff competition from Eli Lilly.

Novo Nordisk

The Danish drugmaker called the changes the beginning of a new chapter, as it has been grappling with stiff competition from chief rival Eli Lilly

In an exclusive interview with CNBC, Novo CEO Mike Doustdar said the rebrand and culture shift are “part of the same package” for the company to evolve its strategy as it tries to win back customers from Lilly.

“I think there’s no secret that over the last four or five years, the external environment and what has happened to Novo Nordisk has really made us reflect how we need to readjust and rethink about the next decade to come and what shifts are needed in our strategic direction,” he told CNBC.

Doustdar said the “work is cut out for us,” adding that Novo needs to improve several aspects – from research and development and manufacturing to sales and marketing – to be able to compete in the obesity drug market.

Shares of Novo have dropped about 15% this year despite the successful launch of the oral version of Wegovy, which surpassed 3 million prescriptions as of June. The company recently scrapped three trials on an experimental cardiovascular drug. That challenge came as it continues to lag in the obesity space with 38.8% market share compared to Lilly’s 60.9% in the second quarter, according to a Lilly earnings presentation citing IQVIA data.

In a release, Novo also announced a broader company rebrand focused around the phrase “Lasting Health Starts Now,” which promotes the idea that patients should make progress toward long-term well-being immediately rather than later. The company said the marketing is a bid to build relevance and trust with the public and other stakeholders, and bring “breakthrough science closer to people’s daily lives.”

When asked whether the rebrand and cultural overhaul were driven by Novo’s recent market share losses in obesity, Doustdar said the changes were less about competitive setbacks and more about adapting to a dramatically different operating environment.

He said the rapid growth of obesity treatments has transformed Novo’s patient base and shifted the market toward a more consumer-oriented model, where patients move on and off therapies more frequently than in traditional diabetes care. As a result, Doustdar said Novo needs to become more focused on meeting patients where they are, while increasing the speed and clarity of its decision-making to keep pace with the evolving market.

“Our operating environment phenomenally changed compared to just 10 years ago,” he told CNBC.

Novo Nordisk will remain the legal name for the company, according to the release. That original name dates back to the 1989 merger of two competing Danish pharmaceutical companies: Novo Terapeutisk Laboratorium and Nordisk Insulinlaboratorium.

The drugmaker said its corporate culture will be based on a new set of four principles that will help it gain advantages in an increasingly competitive market where more of its products have gone direct-to-consumer.

Those tenets are innovating with patients as the primary focus, raising the company’s performance to “create greater value for all stakeholders,” setting clearer priorities and simpler workflows and never compromising on patient safety and ethics.

“When you think about strategy, that’s really the the journey you’re taking and the direction you’re setting the company to go forward with,” Doustdar said. “But you also need behaviors. You need a cultural element that allows your colleagues and yourself to really make sure that a strategy gets executed.”

Despite its challenges, Novo has had one significant tailwind this year in the launch of the oral version of Wegovy. On top of its explosive launch, the pill had a head start over a rival weight loss pill from Lilly called Foundayo.

Doustdar said Novo has maintained “a lion’s share” of the oral market even with competition, noting that physicians find the Wegovy pill to be more effective than Lilly’s, with around 17% of weight loss.

Iran Claims It Shot Down U.S. Advanced Drone Near Hormuz as Middle East Tensions Rise

Iran says it shot down an advanced U.S. drone over the Strait of Hormuz amid rising tensions and stalled diplomacy. President Trump linked the conflict to potential oil control, citing the Venezuela deal and predicting lower gas prices if the war ends.

Iran’s military announced it had shot down a sophisticated American drone above the Strait of Hormuz, marking the latest volley in a cycle of warnings and strikes between Tehran and Washington that shows no sign of easing.

The Islamic Revolutionary Guard Corps stated on Monday that its newly unveiled advanced aerospace defense system intercepted and destroyed an advanced MQ‑1 drone over the Hormuz strait, offering no further details about the drone’s mission. The MQ‑1, built by U.S. defense contractor General Atomics, has historically been flown mainly by the U.S. Air Force and the CIA.

The downing comes after a string of Iranian actions targeting U.S. unmanned naval assets in the Gulf, as the conflict, now in its seventh month, continues with little de‑escalation and diplomatic efforts over the vital waterway remain stalled.

On Sunday, President Donald Trump said the United States could keep pressing its campaign against Iran and seize control of its oil, comparing the situation to the agreement Washington reached with Venezuela earlier this year.

“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump remarked at the Irish Open golf championship in Ireland. He added that the revenue the U.S. gains from the Venezuela deal — which gave Washington access to about one‑fifth of Venezuela’s oil reserves — has “paid for the war many times.”

Under the August agreement, Venezuela handed over majority U.S. control of more than 65 billion barrels of oil reserves — more than twice the size of America’s own reserves — in exchange for $209 billion deposited into Venezuela’s state treasury. Secretary of State Marco Rubio said the pact would also attract roughly $100 billion in private investment to help revive the Venezuelan economy.

Trump also said on Sunday that he expects the seven‑month Iran war to conclude this year, perhaps after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once the conflict ends.

He stressed that he would only accept the “right deal,” noting that Tehran has been “calling constantly” for peace talks, a claim Iran has previously rejected.

**Stalled Hormuz talks**

A planned meeting in Oman between Gulf states and Iran to discuss possible arrangements for the Strait of Hormuz — the crucial conduit for global oil and gas shipments — was postponed, Omani Foreign Minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”

Iranian and Gulf officials had been slated to meet on Monday to sign an accord establishing an Iran‑Oman shipping lane through the Strait of Hormuz, although no direct negotiations between the United States and Iran were underway at that time.

Since the war began in February, the Strait of Hormuz has been under an Iranian‑led naval blockade, later joined by U.S. forces, keeping global energy prices elevated.

A June agreement between Washington and Tehran collapsed over disagreements about the waterway, and a recent surge in attacks by Yemen’s Houthi rebels — an ally of Tehran — has given that group leverage over another key chokepoint, the Bab el‑Mandeb.

Vessels deemed non‑compliant are routinely struck by Iranian forces, while the United States periodically launches strikes on the Iranian coast to challenge the Islamic Republic’s hold on the strait.

Oil prices climbed above $100 a barrel again for the first time since May and rose further on Monday after Saudi Arabia shut a major East‑West energy pipeline following damage from Iraqi drones.

U.S. West Texas Intermediate futures gained 2.3% to $102.39 per barrel, and Brent crude, the global benchmark, rose 2.4% to $107.11 per barrel.
