Twitter last week said it will allow only paid subscribers to use text messages as a two-factor authentication (2FA) method to secure their accounts.
After 20 March, “only Twitter Blue subscribers will be able to use text messages as their two-factor authentication method”, the company tweeted.
Two-factor authentication, meant to make accounts more secure, requires an account holder to use a second authentication method in addition to a password. Twitter allows 2FA by text message, authentication app and a security key.
The company believes phone number-based 2FA is being abused by “bad actors”, according to a Wednesday blog post that the company’s tweet linked to.
Twitter owner Elon Musk tweeted “Yup” in reply to a user tweet that the company was changing policy “because Telcos Used Bot Accounts to Pump 2FA SMS”, and that the company was losing US$60-million/year “on scam SMS”.
The blue checkmark, previously free for verified accounts of politicians, famous personalities, journalists and other public figures, is now open to anyone prepared to pay.
Last month, Twitter said it would price Twitter Blue subscription for Android at $11/month, the same as for iOS subscribers. — Reuters

Snapchat’s social media app is adding users at a faster clip, reaching more than 750 million per month, Snap CEO Evan Spiegel said.
That’s 25% more than the 600 million monthly users the app, known for its disappearing photo messages, was attracting 10 months ago. For the year through April 2022, the monthly count rose 20%, the company said.
Spiegel announced the numbers Thursday to an audience of investors at a meeting in Santa Monica, California. Those investors will be listening for signs that the company’s plan to shift its strategy is paying off. Snap last year said it was scaling back operations and narrowing its focus to three priorities: adding users and getting them to spend more time on Snapchat; jump-starting revenue growth; and investing in augmented reality technology.
The numbers disclosed on Thursday signal that the app can continue to expand its user base, which may help counter major declines in its digital ad business. In the first quarter, analysts expect the company’s revenue to post the first-ever drop from a year earlier, while the amount of money Snap makes per user is projected to fall to the lowest in almost three years.
The company has already said that the slide in digital marketing spending that’s hurt the industry for the past year is leveling off. Meanwhile, Snap is making changes to its ad offerings this year that may drag on revenue in the first quarter.
While Snapchat isn’t the biggest social media app — Meta Platforms Inc.’s Facebook and Instagram see about 3 billion and 2 billion users a month, respectively — it’s known for being especially popular among young people. In recent years, its been competing for the attention of younger users with TikTok, the fast-growing video app owned by ByteDance Ltd., which has more than 1 billion people logging in every month. — Bloomberg LP

Mustek subsidiary Rectron has teamed up with Chinese drone maker DJI to launch a drone academy in Midrand, north of Johannesburg.
The academy will offer three courses that aim to enhance the skills and proficiency of drone pilots. The courses offer a “remotely piloted aircraft systems maintenance technician” certification, remote pilot’s licence and “beyond visual line of sight” certification.
The duration of each course is three or four months and covers theoretical and practical training. At a launch event in Midrand on Friday, Rectron highlighted the challenges the drone industry faces, including a shortage of skilled professionals, limited applications in rural areas as well as regulatory hurdles. The company wants to promote the further use of drones across industries as it continues to diversify its business as a distributor of ICT products, including drones.
Rectron is offering learnerships aimed at enhancing the digital skills of the youth, too. According to Andre Witbooi, learning and development manager at Rectron, the construction, agriculture and insurance sectors are the top three industries in South Africa that depend on drones. Nevertheless, the shortage of skilled drone pilots and technicians is a significant impediment to the industry’s further growth.
“As the world moves towards a more digital economy, we need to ensure our youth have the right skills to take part in it,” said Witbooi. “The Rectron Drone Academy aims to provide relevant training for a future-proof career in the drone space. For many businesses that need to survey large areas, drones offer a cost-effective alternative to helicopters and aircraft.
“When it came to structuring the courses, we consulted with the NTSU Drone Academy and DJI to ensure students have the right foundations and training to forge a career path as a professional. All our courses are accredited with the South African Civil Aviation Authority.”
Thandanani Manyathi, regional coordinator at the Media, Information and Communication Technologies Sector Education and Training Authority (MICT Seta), highlighted the contribution of South Africa’s commercial drone industry to job creation and the economy.
Manyathi said drones are beneficial in agriculture as they increase efficiency, precision and reliability of crop farming.
Although drone regulations have been enforced in South Africa, the rapid evolution of the industry makes it difficult for regulations to keep up with the technology, according to the Drone Council of South Africa.
The Rectron Drone Academy in Midrand will admit its first cohort of five students on 20 February, and students who have completed matric can enrol for the courses. Although it is not a prerequisite, having a background in maths and science is advantageous for admission. – NewsCentral Media

Alphabet lost US$100-billion in market value on Wednesday after its new chatbot shared inaccurate information in a promotional video and a company event failed to dazzle, feeding worries that the Google parent is losing ground to rival Microsoft.
Alphabet shares slid as much as 9% during regular trading with volumes nearly three times the 50-day moving average. They pared losses after hours and were roughly flat. The stock had lost 40% of its value last year but rallied 15% since the beginning of this year, excluding Wednesday’s losses.
Reuters was first to point out an error in Google’s advertisement for chatbot Bard, which debuted on Monday, about which satellite first took pictures of a planet outside the Earth’s solar system.
Google has been on its heels after OpenAI, a start-up Microsoft is backing with around $10-billion, introduced software in November that has wowed consumers and become a fixation in Silicon Valley circles for its surprisingly accurate and well-written answers to simple prompts.
Google’s live-streamed presentation on Wednesday afternoon did not include details about how and when it would integrate Bard into its core search function. A day earlier, Microsoft held an event touting that it had already released to the public a version of its Bing search with ChatGPT functions integrated.
Bard’s error was discovered just before the presentation by Google, based in Mountain View, California.
“While Google has been a leader in AI innovation over the last several years, they seemed to have fallen asleep on implementing this technology into their search product,” said Gil Luria, senior software analyst at DA Davidson. “Google has been scrambling over the last few weeks to catch up on Search and that caused the announcement yesterday (Tuesday) to be rushed and the embarrassing mess up of posting a wrong answer during their demo.”
Microsoft shares rose around 3% on Wednesday, and were flat in post-market trading.
Alphabet posted a short gif video of Bard in action via Twitter, promising it would help simplify complex topics, but it instead delivered an inaccurate answer.
In the advertisement, Bard is given the prompt: “What new discoveries from the James Webb Space Telescope (JWST) can I tell my 9-year old about?” Bard responds with a number of answers, including one suggesting the JWST was used to take the very first pictures of a planet outside the Earth’s solar system, or exoplanets. The first pictures of exoplanets were, however, taken by the European Southern Observatory’s Very Large Telescope (VLT) in 2004, as confirmed by Nasa.
“This highlights the importance of a rigorous testing process, something that we’re kicking off this week with our Trusted Tester programme,” a Google spokesman said. “We’ll combine external feedback with our own internal testing to make sure Bard’s responses meet a high bar for quality, safety and groundedness in real-world information.”
Alphabet is coming off a disappointing fourth quarter as advertisers cut spending.
The search and advertising giant is moving quickly to keep pace with OpenAI and rivals, reportedly bringing in founders Sergey Brin and Larry Page to accelerate its efforts.
“People are starting to question, is Microsoft going to be a formidable competitor now against Google’s really bread-and-butter business?” said King Lip, chief strategist at Baker Avenue Wealth Management, which owns Alphabet and Microsoft shares.
Lip cautioned, though, that concerns about Alphabet may be overblown, saying: “I think still Bing is a far, far cry away from Google’s search capabilities.”
The new ChatGPT software has injected excitement into technology firms after tens of thousands of job cuts in recent weeks and executive pledges to pare back on so-called moonshot projects. AI has become a fixation for tech executives who have mentioned it as much as six times more often on recent earnings calls than in prior quarters.
The appeal of AI-driven search is that it could spit out results in plain language, rather than in a list of links, which could make browsing faster and more efficient. It remains unclear what impact that might have on targeted advertising, the backbone of search engines like Google.

Lithium-rich African countries, including Zimbabwe and Namibia, are trying to develop processing and refining industries to capture more of the profits of global demand for the battery material.
As the motoring industry shifts towards electric vehicles — spurred by proposed bans on fossil-fuel cars beginning at the end of the decade — lithium prices and demand have soared.
China, the world’s top lithium refiner and a leading producer dominates the supply chain, but Western governments and international companies are trying to challenge that and see Africa’s lithium reserves as an opportunity.
For their part, African countries are determined to retain more of the value of their resources than they have in the past, which means not just mining them but processing them before export, which economically is referred to as beneficiation.
“We are saying to ourselves, if you have got the minerals that everybody wants now, you need to make sure that at least you probably mine those minerals differently and not in the usual manner,” Namibia’s mines minister Tom Alweendo said in an interview at the Investing in African Mining Indaba in Cape Town.
“We are going to insist that all lithium mined within the country has to be processed in the country.”
Africa’s lithium production is set to rapidly increase this decade. From 40 000 tonnes this year, the continent will likely produce 497 000 tonnes in 2030, commodities trader Trafigura estimates, with the bulk of that coming from Zimbabwe.
Doubled
Prices for lithium more than doubled last year as demand from the electric vehicle industry outstripped supply.
Zimbabwe in December imposed a ban on raw lithium exports, a measure aimed at stopping the smuggling of lithium ore and spurring mines to process in the country.
“We made plans to only allow the export of concentrates,” said the country’s mining minister, Winston Chitando, in an interview. “Because of the ban, other investors have come in wanting to mop up lithium ores and develop them to concentrate stage.”
Mining has often been linked to the exploitation of workers or environmental degradation by foreign powers. In his visit to Democratic Republic of Congo, Pope Francis at the end of January condemned the “poison of greed” for mineral resources that has exacerbated conflict in the country’s east.
The latest effort by African governments is far from the first time they have resolved to retain more of the value of their mineral wealth, which ultimately should boost tax revenue, encourage new businesses and add jobs.
The global transition away from fossil fuels is giving a sense of urgency, although many obstacles remain, notably insufficient electricity supply.
As companies and investors around the world focus on goals to reduce carbon emissions and increase supplies of the minerals that should help, companies and investors are reconsidering projects they may have previously overlooked.
“These are really unique times we are living in, with this whole transition to a clean energy future and Ghana could be part of this story,” said Len Kolff, interim CEO at Atlantic Lithium.
The company’s Ewoyaa mine project is set to be the first lithium producer in the West African country. US firm Piedmont Lithium has signed a deal to get 50% of the lithium produced.
“Everybody’s approaching us, like the whole who’s who on the Chinese list and now it’s all the Western OEMs (original equipment manufacturers),” Kolff said.
