What’s Better: Signal VS. Telegram

Social media platforms have been subject to a lot of criticism in recent years, especially the tech giant Facebook. More intense is the legal repercussions that came with some of that criticism. Setting aside these complex legal debates that the day-to-day social media user doesn’t understand, something that every user can relate to is privacy concerns. It’s not just Facebook either, platforms such as Instagram and WhatsApp have been the center of privacy scandals. With all of this in mind, we’ll be focusing on Signal VS. Telegram and comparing how secure each of these social apps is.

These apps aren’t the most popular, but they aren’t far off. Telegram, in particular, is growing at an impressive rate, and because of its API, there are plenty of ways that developers can implement it as part of their own projects. Signal has much in common with Telegram but is more open-source based. Obviously, there are numerous other things to compare, so let’s get right into it.

Factors to Consider

Rather than your research and compare every aspect of these apps, we’ve saved you the hassle. We’ve chosen the factors that we think are the most important. Below we’ve compared how these factors are reflected in Signal and Telegram.

Privacy Protection and Encryption

The main debate surrounding Signal VS. Telegram is how secure they actually are. Whether the encryptions are strong enough and the general reliability of these apps’ security are at the center of the debate. For a better understanding, this is going to be split into even smaller parts.


What is encryption? In simple terms, encryption is how computers prevent unauthorized people from accessing data. Messaging apps encrypt messages and files that you send so that only the recipient can view them. Telegram and Signal have very different outlooks on encryption.

Telegram uses a custom encryption method called MTProto, specifically developed for the popular messenger. As you’d expect, the developers were hit with a backlash for not using a mainstream, well-known, and reliable encryption method. They quickly refuted any weakness in the encryption and took the bold step of hosting a competition offering $300k to anyone who could successfully intercept the encryption – nobody was successful.

Signal also uses custom encryption, but it has been around for longer and was a widely supported project prior to Signal’s takeover. The Open Whisper System is open-source encryption that enforces end-to-end encryption (like Telegram). We could get more technical about the encryption, but for many reasons, Signal is believed to have the superior encryption technology in place.

Disappearing Messages and Media

Similar to Snapchat, Telegram lets you add a timer to you send. When you send any type of media, you can set a “Self-Destruct Timer” ranging from 5 to 60 seconds. Messages can also be deleted up to 48 hours after being sent.

Self-Destruct Timer

Signal has an identical feature, with two improvements. First, you can also add the timer to your text messages. Instead of having to delete them and risk missing the 48-hour deadline manually, a timer deals with it instead. Secondly, the timer is a lot longer and ranges from 5 seconds to 7 days.

Secret Chat

Secret chat is where a spotlight is shone on each app’s encryption abilities and Signal VS. Telegram is almost settled.

Telegram’s secret chat feature is where you can use the “Self-Destruct Timer,” and anything sent here is encrypted. However, after further investigation, this is the only place where Telegram uses encryption. Unless you use the secret chat, your messages will have no protection. On the other hand, Signal has constant encryption in play.

Secret Chat

You might ask, “why doesn’t everyone just use secret chat then?”, and this would be a solution. Unfortunately, some too many users don’t know about this feature. Moreover, it isn’t clearly shown. Users can only access it by going to a contact’s page and tapping the settings icon.

To prove we’re not being biased against Telegram, one thing it offers that Signal has yet to add is Two Factor Authentication. A subtle but nonetheless important account security feature.

Our final comment on secret chat: Telegram users have realized that secret chat media actually isn’t secret. Even if you send photos with a timer on them, Android users can save the photos by viewing the app data. This is a serious problem with Telegram that reduces the efficiency of secret chat.

By the way, switch to them if you are looking for the best Instagram private profile account viewer and Telegram Spy tool or want to find out how to hack Facebook messenger without password easily.


Endorsements don’t really say a lot about the software itself. There are a couple of important names that prove the strength of these apps’ encryption, though.

Edward Snowden, a man who whistle blew a lot of concerning details about the American government, and Bruce Schneier, a notable computer program who is praised for this cryptography and cybersecurity skills, are both advocates of Signal’s encryption.

Both men have lots of knowledge of encryption and internet privacy. These two endorsements are powerful enough to label Signal as the most private and secure messaging app available.

UI Design

Everything you see on your screen falls under the umbrella of the UI design. Icons, menus, responsiveness, and layout are just a few focuses on the UI design. A fairly simple, yet popular, UI feature that both apps include is dark mode. This adjusts the app’s color scheme so that it isn’t as bright as the regular model.

In terms of design flaws, it could be said that both apps fail to provide menus at the bottom of the screen. Sure, this isn’t a requirement, but it makes using apps easier with one hand.
Signal has another disadvantage. After you launch the app, the default display isn’t your contact list but is instead a list of your current chats. This means that to chat, call, or video calls a contact that you haven’t already messaged, you have to use the search bar.

When using Telegram, two versions can be used. Telegram X includes several features that the main app doesn’t, and therefore, you can expect the interface to be different.

Overall, Signal VS. Telegram for the UIs is pretty even. They both have design flaws, but there isn’t anything ridiculous about either UI design.

Account Verification

This can seem like a complex thing to consider when comparing messaging apps like Signal VS. Telegram, but it’s very interesting nonetheless.

When using Signal to text or call, something known as a “Safety Number” is randomly generated for each contact. If you text or message someone, you can both view this number to verify that you’re talking to the correct person and not a fake account.

Seems pointless? Not quite. Let’s say you decide to use Signal for messaging and calling business associates. Whatever information you text them will need to be confidential, and the last thing you want is for it to fall into the wrong hands. Before you send this information, you can check the Safety Number of contact to ensure it’s the right person. Likewise, they can check the Safety Number on their end to make sure they don’t reply to a fake account. Since the Safety Number will be the same for both of you, this is a definitive way of verifying your contacts.

A similar mechanism is in place when you make calls. Signal generates a different security phrase made up of two words. You and the person you call are made aware of this phrase. When you call your contact, you can verify that there’s no interference by saying the first word in the phrase and having them say the second.

Understandably this might not seem like an impressive feature if you use Signal for everyday messaging. However, in cases where sensitive information is being shared, and privacy is of the utmost importance, this is magnificent.

Telegram does not have a similar nor equivalent feature in place. Thus, Signal takes the crown in this aspect of Signal VS. Telegram.


Pricing is always a factor to consider in any comparison. Fortunately, in cases like Signal VS. Telegram, both of the messaging apps are free to use. This includes the iOS and Android apps, as well as computer programs.

Additionally, given that free apps often fill the interface with ads and make the app free, it’s worth mentioning that neither app does this. Signal and Telegram don’t have any form of an advertisement on their apps and are both free to use – that’s a win-win!

Other Features to Consider

Security and privacy are two very important factors to consider when you use a messaging app, but that’s not all. Below we’ve picked out some of the other notable features that Signal VS. Telegram should include.

Group Chats (Telegram Wins!)

Although both the apps provide group chats, Telegram has a significant advantage. Your group chats on Telegram can be extended to as many as 200,000 users – far from common and definitely not an easy feature to maintain. Adding to that, users can send large files (reaching 1.5GB), another unheard-of messaging app capability.

Group Roles (Telegram Wins Again!)

Continuing with the massive groups, you can define group roles. Managing large groups is difficult, especially if you’re a YouTuber or have an online fanbase. Make this easier on Telegram by giving trustworthy members Administrator and Moderator powers.

Maintaining Groups (Telegram… Again?)

Various aspects of groups are what push Telegram to succeed in this Signal VS. Telegram comparison, and here’s what can help you maintain groups:

  • Define a blacklist of words – if a member says a word/phrase on the list, the message deletes automatically
  • Send your GPS location to let the group know where you are (only suitable for small groups)
  • Develop bots and add them to groups. Bots that send welcome messages, block messages from certain roles, or regularly send data (e.g., stock prices) in the chat can all be added

Overall, when groups are taken into consideration, Telegram dominates Signal’s group chat in every way possible. Given that Signal was developed with a keen focus on privacy and security, this can be quickly forgiven.

Conclusion on Signal VS. Telegram

Privacy is what it comes down to for a lot of users. Even more so if they are deciding which app to use for business purposes where they don’t want important information to be leaked. After reading through our comparisons above, and perhaps doing some more research yourself, you’ll hopefully be able to pick your favorite from Signal VS. Telegram. Like we said before: there’s plenty of factors to consider, it just depends on what matters most to you. Whether it’s a slick and minimalist interface, enhanced privacy protection, or the price, there are hundreds of messaging apps out there to choose from.
