As of 2023, Telegram Premium can be acquired via in-app purchases facilitated by Apple and Google, directly via Telegram’s @PremiumBot, or with cryptocurrency on the Fragment platform. Reactions were first added to Telegram in 2021 and expanded to include more emoji options for Premium users. Telegram comes with one default sticker pack, and users can install additional sticker packs provided by third-party contributors.

Premium users have the ability to set any chat folder as the default screen in the app while regular users will always see the full chat list when first opening the app. Messages from private chats can be forwarded, with an option to hide the original sender’s identity or to hide captions from media messages. In September 2015, Telegram announced that the app had 60 million active users and delivered 12 billion daily messages.
The Telegram team responded that the flaw does not affect message security and that “a future patch would address the concern”. Nevertheless, they said they saw “no reason why Telegram should use a less secure encryption scheme when more secure (and at least as efficient) solutions exist”. In December 2015, two researchers from Aarhus University published a report in which they demonstrated that MTProto 1.0 did not achieve indistinguishability under chosen-ciphertext attack (IND-CCA) or authenticated encryption. The EFF said that the results “should not be read as endorsements of individual tools or guarantees of their security”, and that they were merely indications that the projects were “on the right track”.
It encompasses core functionalities including admissions, enrollment, course scheduling, grades and academic records, performance tracking, and financial management.
A few days later, following repeated criticism, the same judge suspended his order until the police issue a report on the consequences this measure would have for users. Scammers employ a variety of confidence tricks to entice users into completing “prepaid tasks” in which users deposit money into scammers’ accounts with the expectation of receiving high returns. But deputy prime minister and minister of digital transformation Mykhailo Fedorov denied that any data from the app had leaked.
For encrypted chats (branded as Secret Chats), Telegram uses a custom-built symmetric encryption scheme called MTProto. Telegram stated that it does not have access to the data, while the platform will share the information only with the authorized recipient. When an online service requires such identification documents and verification, it forwards the information to the platform with the user’s permission. It features a website widget that could be embedded into websites, allowing users to sign into a third party website with their Telegram account. Telegraph natively supports Instant View, a feature which lets users read full articles in the chat with no load time and without opening an external browser. In October 2024, Telegram launched Gifts, a type of virtual cosmetic item that users can purchase and send to each other in the app using Telegram Stars.
Since July 2016, Line has also applied end-to-end encryption to all of its messages by default, though it has also been criticized for being susceptible to replay attacks and the lack of forward secrecy between clients. When the user assigns a local password in the desktop application, data is also locally encrypted. The most common mode of fraud involves scammers sending messages to unsuspecting users, offering part-time online jobs that comprise a series of tasks. The same year, Telegram reportedly banned more than 350,000 bots and channels, including those that contained child abuse and terrorism-related content.
In September 2021, Telegram added interactive emoji, a type of animated emoji which also play a fullscreen effect in the chat. When typing in an emoji, the user is offered to send the respective sticker instead. Stickers are cloud-based, high-resolution images intended to provide more expressive emoji.
Telegram then gained over 70 million new users as a result of an outage which affected Facebook and its affiliates on 5 October 2021. On 8 January 2021, Pavel announced in a blog post that Telegram had reached “about 500 million” monthly active users. On 24 April 2020, Telegram announced that it had reached 400 million monthly active users. According to the US Securities and Exchange Commission, as of October 2019, Telegram had 300 million monthly active users worldwide. By March betzino casino 2018, that number had doubled, with Telegram reaching 200 million monthly active users.
After learning about Telegram and reading about encryption, you might be wondering if default encryption really matters. Even if you are just curious about how Telegram works, these tools turn it into more than just a place to chat. If you are a developer, Telegram API for apps allows you to tap into Telegram’s robust infrastructure to build your own applications. Imagine being able to program Telegram to perform tasks beyond just sending messages, such as answering inquiries, setting reminders, or even engaging in gameplay. Your priorities will guide which app is the best fit for you. WhatsApp keeps things simple with minimal customization and end-to-end encryption as the standard, focusing on secure, straightforward communication.
On 9 June 2019, The Intercept released leaked Telegram messages exchanged between current Brazilian Minister of Justice and former judge Sérgio Moro and federal prosecutors. Login SMS messages are known to have been intercepted in Iran, Russia and Germany, possibly in coordination with phone or telecom companies. In April 2016, several Russian opposition members’ accounts were hijacked by intercepting the SMS messages used for login authorization. MTProto 2.0 is seen by qualified cryptographers as a vast improvement to Telegram’s security.
Auto download settings can also be applied based on chat type such as group, channel or private. Similarly, users can hide their phone number and profile photo from people based on categories such as Non-Contacts or by adding exceptions. In the Privacy and Security submenu of Settings, users have the option to hide their “Last Seen” status, which reflects the last time the user opened a Telegram app. Whenever a new device successfully logs in to a user’s account, a special service notification is sent and a login alert is displayed in the chat list of their other devices.
What makes Telegram different is its private chat feature called “Secret Chats.” Additionally, it’s a cloud-based platform, meaning you can effortlessly access your messages across multiple devices. While its regular chats lack full end-to-end encryption, its balance of speed, security, and functionality makes it a top-tier desktop messaging solution. Telegram retains its minimalist interface keeps things sleek and clean; it’s packed with features that appeal to both casual users and tech-savvy power users such as instant saving of media and files on its cloud folder on PC. The National Security and Defense Council of Ukraine enforced the restrictions following evidence reported to them by Kyrylo Budanov, showing Russia’s ability to access messages and user data on the platform.
Telegram has various client apps, some developed by Telegram Messenger LLP and some by the community. Telegram Messenger LLP has servers in a number of countries throughout the world to improve the response time of their service. As with most instant messaging protocols, apart from XMPP, Telegram uses centralized servers. However, the service was criticised for being vulnerable to online brute-force attacks. In July 2018, Telegram introduced their online authorization and identity-management system, Telegram Passport, for platforms that require real-life identification. For example, an article titled “Telegraph (blog platform)” published on 17 November would receive the URL /Telegraph-blog-platform-11-17.
Telegram made substantial efforts to ban illegal content such as child abuse and pro-terrorist channels, including a partnership with Europol to eliminate IS presence on the platform, but communities of far-right extremist users are still on the app. Premium users have access to extra stickers, emoji, reactions, and customization features like a special badge and the ability to change the look of their messages in chats. Telegram’s default chat function missed points because the communications were not encrypted with keys the provider did not have access to, users could not verify contacts’ identities, and past messages were not secure if the encryption keys were stolen. Telegram’s FAQ page says it does not process requests related to illegal content in chats and group chats, and that “to this day, we have disclosed 0 bytes of user messages to third parties, including governments”.
In a later blog post, Durov directly stated that the block was a result of pressure from Google and Apple as refusal to comply with their policies would result “in an immediate shutdown of Telegram for millions of users”. The messages were considered vulgar, racist, and homophobic, with members of the chat discussing how they would use the media to target potential political opponents. In July 2024, ESET reported a vulnerability allowed malicious files being sent to users masked in multimedia. It took 11 days for the database to be taken down, but the researchers say the data was accessed by other parties, including a hacker who reported the information to a specialized forum. On 30 March 2020, an Elasticsearch database holding 42 million records containing user IDs and phone numbers of Iranian users was exposed online without a password.
Secret Chats use End-to-End Encryption to ensure that a message can only be read by its intended recipient.We keep expanding the boundaries of what you can do with a messaging app. SiS is the campus database used to manage student academic data for admissions, registration, enrollment, billing and financial aid. NOVA’s Student Information System (SIS) is your central source for accessing all your essential student information. Additional features are in development to improve the student experience. Transitioning to a new SIS can present unique hurdles, like data migration and user adoption. By merging student information management with essential financial and HR functions, we can bridge the gaps between data and departments.
The company only partially fulfilled a court request for personal data on two antisemitic Telegram groups, which authorities considered an intentional lack of cooperation. Throughout 2020, the Islamic Revolutionary Guard Corps used groups and channels to dox Iraqi and Iranian citizens, while sharing propagandistic posts on the platform. In 2023, Saudi Arabia’s Global Center for Combating Extremist Ideology (Etidal) reported that in collaboration with Telegram, over 59 million pieces of extremist content had been removed from the platform since 2022. In September 2024, Telegram announced that it would begin to hand over users’ IP addresses and phone numbers to authorities who have search warrants or other valid legal requests. Such content is usually linked to Telegram allowing misinformation on the platform as, according to Pavel Durov, “conspiracy theories only strengthen each time their content is removed by moderators”.
