This means only the sender and receiver can see them, even if someone else tries to intercept them.<\/p>\n<p>It&#8217;s used by billions of people worldwide and by many messaging apps besides Signal itself.<\/p>\n<p>The Signal Protocol was developed in 2013 by Open Whisper Systems, a non-profit group of software developers. Today, it is considered the industry standard for end-to-end encrypted messaging and is used by big names in the tech industry.<\/p>\n<p>Services that use the Signal Protocol, either entirely or with closed source modifications, include:<\/p>\n<ul>\n<li>Signal<\/li>\n<li>WhatsApp<\/li>\n<li>Facebook Messenger<\/li>\n<li>Skype<\/li>\n<li>Google<\/li>\n<\/ul>\n<p>Telegram uses its in-house &#8216;<strong>MTProto<\/strong>&#8216; to scramble messages to keep them confidential. It uses a combination of powerful encryption techniques to make sure only the sender and receiver can read them. But it is a proprietary protocol, and not publicly audited.<\/p>\n<p>While some chats, such as &#8220;Secret Chats,&#8221; offer end-to-end encryption, messages are stored on Telegram&#8217;s servers by default.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">Telegram by contrast does not end-to-end encrypt conversations by default. Unless you manually start an encrypted \u201cSecret Chat\u201d, all of your data is visible on the Telegram server. Given who uses Telegram, this server is probably a magnet for intelligence services. 3\/<\/p>\n<p>&mdash; Matthew Green (@matthew_d_green) <a href=\"https:\/\/twitter.com\/matthew_d_green\/status\/1789688817160454199?ref_src=twsrc%5Etfw\" target=\"_blank\">May 12, 2024<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<h3>Encryption<\/h3>\n<p>As mentioned above, the Signal app&#8217;s messages, content, and media are encrypted end-to-end, and the encryption happens at the users&#8217; device level.<\/p>\n<p>The default Telegram encryption only takes this approach with Secret Chats. The rest of the private or public messages sent on Telegram are encrypted under a Server-Client Encryption model.<\/p>\n<p>End-to-end encryption means that the data can only be accessed and read or heard by intended recipients.<\/p>\n<h3>Where Telegram and Signal Store Your Data<\/h3>\n<p>The first big difference between Signal and Telegram is what they do with your data and where they store it.<\/p>\n<h4>Telegram: Your Data in the Cloud<\/h4>\n<p>On the other hand, Telegram refers to itself in its privacy agreements as a cloud service. This means that user messages, photographs, videos, content, contacts, documents, and groups are stored in their cloud servers rather than within the Telegram app (except Secret Chat data).<\/p>\n<p>Telegram assures that this method allows users to access backups from any device and that the data is heavily encrypted with encryption keys spread around different servers.<\/p>\n<p>Storing personal user data on the cloud versus storing it on their own devices has pros and cons, but in this case, on-device data outweighs the cloud, as the risk of <a href=\"https:\/\/www.techopedia.com\/biggest-data-breaches-and-cyber-hacks\">cloud security breaches<\/a> and data leaks is ever-present.<\/p>\n<h4>Signal: Data on Your Device<\/h4>\n<p>Signal encryption makes this important &#8220;your-data&#8221; issue straightforward. The company does not store your personal data, conversations, chats, media, or history on servers or the <a href=\"https:\/\/www.techopedia.com\/definition\/2\/cloud-computing\">cloud<\/a>. Instead, it stores all user data locally on the user&#8217;s device within an <a href=\"https:\/\/www.techopedia.com\/definition\/24416\/database-encryption-and-decryption\">encrypted database<\/a>.<\/p>\n<p>Signal may queue end-to-end encrypted messages on its servers when, for example, a message is sent to a device that is momentarily offline. Even then, all messages are end-to-end encrypted, meaning no one, not even Signal, can see them.<\/p>\n<p>For operational purposes, Signal stores minimal technical information on its servers, such as randomly generated authentication tokens, keys, push tokens, and other material necessary to establish calls and transmit messages, but never user data.<\/p>\n<h3>Secret Chats<\/h3>\n<p>Those who use Telegram&#8217;s Secret Chats feature get end-to-end encryption. Secret Chats sounds impressive, especially for a privacy-focused messaging app.<\/p>\n<p>So why doesn&#8217;t Signal have a similar feature? The answer is simple.<\/p>\n<p>All messages sent on Signal can be considered secret chats as they are all end-to-end encrypted. In contrast, Telegram only applies end-to-end encryption for Secret Chats and content or media shared over Secret Chats.<\/p>\n<p>Public and private messages, media, contacts, and your location on Telegram are not end-to-end encrypted (as mentioned above, they are stored in the cloud).<\/p>\n<h3>Disappearing Messages<\/h3>\n<p>Both companies offer another feature: Disappearing Messages. Signal allows users to\u00a0<a href=\"https:\/\/support.signal.org\/hc\/en-us\/articles\/360007320771-Set-and-manage-disappearing-messages\" target=\"_blank\">set, customize, and manage Disappearing Messages<\/a>. Users can set Disappearing Messages as the default for new chats or specific groups through their privacy settings.<\/p>\n<p>Once the time of the disappearing message ends (Signal provides up to 4 weeks), the data of that message is deleted.<\/p>\n<p>Telegram offers Disappearing Messages only in Secret Chats, not in public or private chats. Users can send self-destructing messages on Telegram by tapping on the clock icon in the input field on iOS or the top bar on Android and choosing a time limit.<\/p>\n<p>Both apps offer view-once (Disappearing) media for users who want to share videos or other types of content that automatically deletes itself after being viewed.<\/p>\n<h2><span id=\"what_drives_users_who_prioritize_privacy\">What Drives Users Who Prioritize Privacy<\/span><\/h2>\n<p>While CEO comments and famous celebrities do add a nice twist to the rivalry between apps, users should choose carefully when deciding what app they trust their life communications with.<\/p>\n<p>So what moves the decision-making of a user who prioritizes its privacy?<\/p>\n<p>We propose the key features include <a href=\"https:\/\/www.techopedia.com\/definition\/3294\/open-source\">open source<\/a> or <a href=\"https:\/\/www.techopedia.com\/definition\/4333\/proprietary-software\">closed source<\/a>, <a href=\"https:\/\/www.techopedia.com\/definition\/1115\/storage\">data storage<\/a> and transfer, encryption, and security features.<\/p>\n<h2><span id=\"alternatives_to_signal_and_telegram\">Alternatives to Signal and Telegram<\/span><\/h2>\n<p>If Signal and Telegram don&#8217;t quite fit the bill, there are other secure messaging apps to explore. <strong><a href=\"https:\/\/threema.ch\/en\" target=\"_blank\">Threema<\/a><\/strong>, based in Switzerland, is a strong privacy contender.

So, when it comes to Signal versus Telegram, the crown goes to Signal for its watertight encryption.<\/p>\n<blockquote><p>&#8220;You can think of it like this: Signal is Fort Knox for your chats, while Telegram is a regular bank &#8211; secure, but with a back door a court order could potentially open.<\/p>\n<p>&#8220;If top-notch security is your priority, Signal&#8217;s your personal soldier. If you value features and flexibility more, Telegram might be a better fit.&#8221;<\/p><\/blockquote>\n<p><a href=\"https:\/\/www.linkedin.com\/in\/jstephenkowski\/\" target=\"_blank\"><strong>Stephen Kowski<\/strong><\/a><strong>, Field CTO at <\/strong><a href=\"https:\/\/slashnext.com\/\" target=\"_blank\"><strong>SlashNext<\/strong><\/a>, said:<\/p>\n<blockquote><p>&#8220;Signal is the more secure choice. Signal offers end-to-end encryption (E2EE) by default, whereas Telegram requires activating a &#8220;Secret Chat&#8221; to get E2EE. Signal&#8217;s protocol (the Signal Protocol) is open source, independently audited, and is used to underpin messaging apps like WhatsApp and Google messaging services.&#8221;<\/p><\/blockquote>\n<p>&#8220;Telegram&#8217;s backend is closed-source; they use the MTProto protocol, which is generally considered secure but lacks the same scrutiny\/transparency as the Signal Protocol.&#8221;<\/p>\n<p><a href=\"https:\/\/www.linkedin.com\/in\/cachemerrill\/\" target=\"_blank\"><strong>Cache Merrill<\/strong><\/a><strong>, Founder at <\/strong><a href=\"https:\/\/www.zibtek.com\/\" target=\"_blank\"><strong>Zibtek<\/strong><\/a><strong>,<\/strong> said:<\/p>\n<p>&#8220;I believe Signal is more secure. They encrypt end-to-end all the time, no matter what, and Telegram requires you to toggle the chat into secret mode so it is encrypted. Plus, Signal collects and stores almost no information about me, so there is really less information risk.<\/p>\n<blockquote><p>&#8220;Telegram has a lot more features, and it is pretty cool, but if security is the top priority, I would definitely choose Signal.&#8221;<\/p><\/blockquote>\n<p>We also recommend a close read of <strong>Matthew Green, <\/strong><a href=\"https:\/\/www.techopedia.com\/definition\/1770\/cryptography\"><strong>cryptography<\/strong><\/a><strong> teacher at Johns Hopkins<\/strong>, recent <a href=\"https:\/\/twitter.com\/matthew_d_green\/status\/1789687898863792453\" target=\"_blank\">tweet thread<\/a>, which explores Telegram&#8217;s latest claims against Signal in depth.<\/p>\n<h2><span id=\"the_bottom_line\">The Bottom Line<\/span><\/h2>\n<p>Privacy should be paramount in any conversation about messaging. Perhaps you can take fewer precautions if you are messaging little more than a cat meme around family members.<\/p>\n<p>But any conversation usually creeps toward revealing personal information or private thoughts \u2014 and things said in private should come with the guarantee that they remain private.<\/p>\n<p>We agree with the majority that Signal has stronger security credentials for private conversations, although there is a reason Telegram has more than 900 million users \u2014 it&#8217;s convenient, fast, and mobile-friendly.<\/p>\n<p>We highly recommend you do your own
