Telegram allows edit, unsend sent messages even for the other people on the same chat. It allows to unsend messages shared with the first 48 hours after sending. The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. To adjust the theme, go to Settings > Chat Settings on Android, or Settings > Appearance on iOS. Here you can change the text size, bubble colors, night mode settings, and similar options. Choose Chat Background to set a new wallpaper for your groups.

This is incredibly useful for keeping track of an important URL, getting an image to another device without cloud storage, or keeping a record of important information.

Telegram offers a few other handy options in chats. You can delete any message by long-pressing it, then hitting the Trash icon that appears. The app lets you delete messages at any time—even messages that the other person sent in a chat. Most people use third-party apps to make sure that no one gets a hand on their private conversations. Telegram, however, has its own lock function to hide privates messages behind a passcode. Sent a picture without adding your usual filter or marking the text you wanted to highlight? Sent the wrong picture altogether? Telegram can help you out. The app allows users to edit photos and even replace them after you have sent it. In general, Telegram is as safe or safer than most other chat apps. It could be argued that WhatsApp’s end-to-end encryption on all messaging is a better approach, but the company’s ties to Facebook/Meta may turn off privacy advocates.

Another security feature that adds usability is usernames. Instead of giving people your phone number, you can simply give them your username. This gives you better control over what information is out there, and how people can contact you in the future. Telegram has a unique feature called Channels that allow you to broadcast messages to large audiences. Unlike Groups, Telegram Channels can have an unlimited amount of subscribers, and only admins have the right to post content.
