The incident has raised questions about Signal\u2019s security and why government officials were using it. (Federal officials are generally not allowed to install Signal on their government-issued devices.)<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Here\u2019s what to know.<\/p>\n<h2 class=\"css-13o6u42 eoo0vm40\" id=\"link-17c69b5f\">What is Signal used for?<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">Signal is an encrypted messaging application that is used to communicate securely. It encrypts messages from end-to-end, meaning that what a user says is encrypted on their device and isn\u2019t decrypted until it reaches the recipient. This method protects the message from being intercepted and read by anyone, including internet service providers, hackers or Signal itself, while it is in transit.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-1\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Users can also set Signal messages to disappear after a certain length of time. Users who want their messages to disappear can turn on the feature in the settings for each of their individual chats.<\/p>\n<h2 class=\"css-13o6u42 eoo0vm40\" id=\"link-48a05524\">Who owns Signal?<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">Signal is owned by an independent nonprofit in the United States called the Signal Foundation. It is funded by donations from its users and by grants.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The foundation was started in 2018 with a $50 million donation from Brian Acton, a co-founder of WhatsApp, another messaging platform that was purchased in 2014 by Facebook. Mr. Acton left WhatsApp to start the Signal Foundation after disputes with Facebook, which is now known as Meta, about plans to make money from his messaging service.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Mr. Acton joined Moxie Marlinspike, a cryptographer who designed Signal\u2019s security system, to create the Signal Foundation. The foundation is structured to prevent Signal from ever having an incentive to sell user data. <\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cThere are so many great reasons to be on Signal,\u201d Mr. Marlinspike, who stepped down from the foundation\u2019s board in 2022, wrote in a post on X Monday. \u201cNow including the opportunity for the vice president of the United States of America to randomly add you to a group chat for coordination of sensitive military operations. Don\u2019t sleep on this opportunity.\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-2\">\n<div class=\"css-53u6y8\">\n<h2 class=\"css-13o6u42 eoo0vm40\" id=\"link-21d91812\">Is Signal secure?<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">Yes. Signal is widely regarded as the most secure messaging app on the market, because of its encryption technology and other measures designed to secure users\u2019 data.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Its underlying encryption technology is open source, which means the code is made public and allows technologists outside the nonprofit to examine it and identify flaws. The technology is also licensed and used by other services, like WhatsApp.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">That encryption technology has been key when Signal has been a target of foreign hackers. Russia has attempted to <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2023\/07\/03\/technology\/russia-ukraine-surveillance-tech.html\" title=\"\">surveil when Ukrainians are using Signal<\/a>, and in February, <a class=\"css-yywogo\" href=\"https:\/\/thehackernews.com\/2025\/02\/hackers-exploit-signals-linked-devices.html?m=1\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">Google researchers said<\/a> that Russian hackers had tried to hijack users\u2019 Signal accounts. While the second attack was effective, it worked by tricking users into adding rogue devices to their Signal accounts, not by breaking Signal\u2019s encryption.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cPhishing attacks against people using popular applications and websites are a fact of life on the Internet,\u201d said Jun Harada, a Signal spokesman. \u201cOnce we learned that Signal users were being targeted, and how they were being targeted, we introduced additional safeguards and in-app warnings to help protect people from falling victim to phishing attacks.\u201d<\/p>\n<p class=\"css-at9mc1 evys1bk0\">In the event of a security breach, Signal is designed to retain as little user data as possible, so that minimal information is exposed. Unlike other messaging services, the company doesn\u2019t store users\u2019 contacts or other identifying data that could indicate how a person used the service.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-3\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">That doesn\u2019t mean Signal is the ideal service for communicating war plans. If a user\u2019s device is compromised, their Signal messages could be read \u2014 and using a government-approved communication system could prevent officials from inadvertently including a journalist in a war planning discussion.<\/p>\n<h2 class=\"css-13o6u42 eoo0vm40\" id=\"link-63cd3b94\">Is Signal safe for texting?<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">Yes, generally, although users should be careful to vet new contacts, just as they might on any other social platform.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">And when adding people to their group chats, they may want to take an extra moment to make sure they\u2019ve included the right contacts.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<p><script async
