Request to join a public group Telegram also supports hashtags. If you tap a hashtag, you can search across all of your activate chats for it. This makes it easy to find messages in the future or categorize information for yourself. Advanced Chat Options
If your device is stolen or someone took it, and you don’t want him/her to see the messages in your chat window, then you can simply terminate all the active sessions with just one click using your Mac, Desktop, Linux or Web client. When you turn on that feature, the app automatically switches to dark mode. Go to Settings > Chat Settings and toggle on Auto-Night Mode. The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. Edit Videos
Since Telegram stores chats and files on a remote server instead of your device, you can also access everything (except secret chats) from the web. Access it via the web portal or any of several Chrome extensions. As mentioned above, the use of usernames instead of phone numbers means your account isn’t tied to just one phone. This makes it easier to log in on other devices, allows you to have multiple accounts on the same device, and makes it so you don’t have to share your phone number with someone to add them as a contact in Telegram. How often have you sent a message to a colleague or friend and then realized it is filled with typos? With Telegram, you can quickly make it right with its edit feature. However, Telegram only uses this encryption in calls and in its “secret chats” feature, not in regular chats. Those are only encrypted client to server. Meanwhile, WhatsApp, the supposedly less secure service, has used end-to-end encryption in all messages, calls, and video calls since 2016.
