Perhaps the most important and the best feature of the Telegram app is its security. It is based on the MTProto protocol that is built upon time-tested algorithms. It enables high-speed, reliable message delivery on weak connections. This is useful when you are on your way to a meeting or trying to coordinate with friends at a large event. Rather than sending static locations every minute, you can share your live location with your friend circle for 15 minutes, 1 hour, or 8 hours. Of course, you can stop sharing at any time. As you might now, Telegram allows you to create Channels which is a tool for broadcasting public messages to large audiences. The basic difference between a group and a Channel is the fact that a Channel can have unlimited numbers and the messages you sent inside a Channel are marked with the Channel name and not yours. However, if your channel is very large, it might become difficult to broadcast a message which is ready by everyone before it is lost in other messages. To solve this problem, you can pin messages inside a Channel. To pin a message, just tap on it and tap on Pin. Now the message will always be on top before the reader removes them.
Telegram will now send login codes through email addresses to the users who log out and log in frequently. Users can also Sign in with Apple or Sign in with Google. The company has also added new interfaces and fun animations to Telegram iOS app. Telegram allows users to locate contacts nearby you, should they choose to be discovered. This allows you to quickly add someone close to you on Telegram without going through the hassle of first noting their number and saving the contact manually. Users can also use this feature to find and create groups of nearby users. To lock your messages, go to “Settings”, “Privacy and Security” and tap on “Passcode Lock”. You will be asked to set a four-digit passcode and confirm it. Once you do that, you will find additional options to “unlock the app with fingerprint” and “auto-lock” it after a specific duration. Also, it enables you to send the current location as well. But live location is much more valuable because it’s easy to find your friend or someone in a wide range of situations.
Bot API: lets you build programs that use Telegram messages for an interface. You don’t need to have knowledge of MTProto encryption protocol. The intermediary server will handle all communication and encryption with Telegram API for you. Telegram gives you an option where you can select who can see your last seen time. To configure this, go to “Settings”, “Privacy and Security” and then tap on “Last Seen & Online”. You can share it with everybody, or people in your contact list, or nobody, or add exceptions like “never share with” XYZ. Because Telegram lets you interact with people even if you aren't in each other's contacts, you may wish to make your account more private. To change privacy options, head to Settings > Privacy and Security. Here, you can change who can see your phone number, active status, and more.
