Signal vs. Telegram: What’s the Difference?

Signal and Telegram are both reliable and secure messaging apps. Neither app is owned by a major tech company. Signal is managed by Open Whisper Systems, a non-profit organization. Telegram, on the other hand, is run and owned by a for-profit organization. Telegram was founded in 2013 by Russian businessman Pavel Durov. Signal and Telegram are standard messaging apps with features like stickers, files, video transfer, and voice and video calls. Both apps are free, and only your phone number is required to sign up. Signal and Telegram also provide optional web applications to connect through your Windows PC, Linux or Mac.

That said, let’s dive deep and look at more features between Signal and Telegram to know what each one offers to help you make the best choice.

Security and Privacy

In terms of security and privacy, Signal is your best bet. All signal messages are, by default, end-to-end encrypted, which means no third party can access your conversations. In comparison, Telegram expands the data shared limit, which leaves other messages to be potentially visible to other third parties, as end-to-end encryption is done to messages in the “secret chat” option only.

Signal’s encryption protocol (formerly known as the TextSecure protocol) is open-source and available for anyone to see and examine, meaning any security flaws can be quickly identified and fixed. Telegram uses MTP 2.0 protocol, an upgrade from MTProto 1.0, to encrypt its “secret chat” option messages, which is open-source on the client side. Telegram’s encryption method, through security experts, is said to have more limited track records than Signal. This results from the latest protocol being more secure than the MTProto 1.0 version.

Also, Signal collects less data on users than Telegram. Signal only stores the date and the phone number used to sign up, as well as your last connection time. Comparably, Telegram’s metadata provides your IP address which links to your location, who you are in contact with, and when.


Signal and Telegram both support the most popular platforms, including Linux, Windows, MacOS, iOS, and Android. They also offer a Chrome browser extension to allow web-based access.

Also, Telegram supports Windows OS and allows universal access to unencrypted messages through a website access portal from the servers. It is worth noting that Telegram’s “secret chat” option is available only through the mobile application and not through web-browser access.

A notable difference between Signal and Telegram is that Signal service depends on Google services for notifications. Practically, this only applies to devices with custom Android OS.

Usability and Installation

Both Signal and Telegram are relatively easy to use and install. Download the software through the platform of your choice, and you’ll only need to sign up using your phone number and verify using an SMS or a call with a code in the case of Telegram.

In both services, you can anonymously configure your account if necessary. Telegram has detailed options to set up for user experiences, such as themes and colors, whereas Signal has similar but basic ones. This makes Signal an easy app to use and set up.

Telegram focuses more on social media messaging and broadcasting, while Signal focuses on secure messaging. Telegram supports sending uncompressed images, making it a better messaging app when compared to Signal for sharing photos. However, Signal has a face-blur feature installed by default for use when sending images.

In terms of support, both apps rely on online help or a volunteer to address specific issues, as they both operate on a non-commercial basis. Signal has the upper hand in providing a more secure messaging app, as it also supports visually impaired users.

User Experience

You can customize Telegram to enhance the user experience by adjusting several settings, from themes, font sizes, colors, emojis, animations, and notifications. The app can create a playlist when sent a list of songs and launch them in its in-built media player. You also can conduct surveys and quizzes, edit images and videos, and view other individuals within your proximity with the People Nearby feature (though it may raise privacy concerns).

On the other hand, Signal is a simple application that has a focus on sending text, audio, and video messages securely. Recently, Signal has introduced animated stickers as part of its available emojis. Comparably, Signal is easy to use and requires minimal customization for a top-notch user experience.

Data Storage

Unless the “secret chat” option is enabled, Telegram collects and stores its messages in a cloud-based platform. Telegram claims to store its data across distributed databases, and the encryption keys are stored in the server, thus allowing them to decrypt messages. Similarly, if Telegram is a target for attack, the rival can access all user data, including chat information. This makes Telegram a threat to companies that actively archive messages with intentions to meet mobile company compliance.


Signal wins on privacy and security due to its robust encryption measures. However, we need to find out which messaging app is better for users operating within the confines of mobile compliance guidelines. 

Telegram offers optional end-to-end encryption and protects messages only in the “secret chat” option. Consequently, users’ communications on Telegram remain vulnerable to cyber threats in unsecured environments. Contrary, Signal, by default, offers end-to-end encryption, making it a more secure option for your communications. For companies running in highly regulated sectors, such as banking and finance, education, healthcare, and pharmaceuticals, encryption in messaging is crucial for mobile compliance.

Therefore, it’s recommended that businesses use Signal to Telegram. However, this practice becomes effective in enterprise messaging solutions and when companies archive text messages. Regardless of the platform you are using, companies must emphasize the coverage of all communications between employees and stakeholders to maintain mobile compliance.

Signal vs. Telegram: What’s the Difference, Which One Is Better? FAQs (Frequently Asked Questions) 

Signal vs. Telegram, which is more secure?

Both Signal and Telegram are popular messaging apps known for their security features, but they have different approaches to encryption. Signal is widely regarded as one of the most secure messaging apps available. It uses end-to-end encryption by default for all messages, calls, and media shared within the app. This means that only the intended recipients can decrypt and read the messages, ensuring a high level of privacy and security. Signal also encrypts metadata, such as the sender and receiver information.

Telegram, on the other hand, offers optional end-to-end encryption through its “secret chat” feature. This means that users need to enable secret chats for their conversations to be encrypted. Regular chats on Telegram are not end-to-end encrypted, although they do use server-client encryption for secure transmission.

While both apps prioritize user privacy and security, Signal’s default end-to-end encryption for all communications provides a stronger level of security compared to Telegram’s selective encryption approach.

Do both apps offer encryption?

Yes, both Signal and Telegram offer message encryption, but in Telegram, you have to move chats to the “secret chat” option for end-to-end encryption, whereas Signal encrypts all chats by default.

Is Signal better than Telegram?

In terms of security and privacy, Signal wins the battle due to its robust encryption measures. However, Telegram has a better-looking user interface and enjoyable group chat features for enhanced user experience. Telegram is also widely known and used.

Does Signal monetize your data?

No, Signal is owned by a non-profit organization. Grants and donations from individuals and organizations support its mission to offer security and privacy. It also collects and stores minimal information adequate to carry out its messaging service.

Does Signal have servers for data storage?

No. Unlike Telegram, which stores usual private and group chats on its servers, Signal stores its files and messages locally since they are end-to-end encrypted, and Signal service can’t access them.
