How Telegram Web Works in a Browser
Telegram Web lets you read chats in Chrome, Firefox, Safari, or Edge without installing Desktop. It is useful on shared office PCs and Chromebooks.
Check the Address Bar First
The hostname should be web.telegram.org. Telegram Web A lives at /a/, Web K at /k/. Bookmarks should point there, not at a shortened link from a message.
QR Login on Official Web
On the official page, Telegram can show a QR code. You scan it from Settings → Devices on the mobile app. If a page asks you to scan with a different messenger, or the address is not telegram.org, stop.
When Desktop Is Better
If you need file-heavy work, system notifications, or multi-account switching all day, Desktop is usually more stable than a browser tab. Web remains a good fallback when you cannot install software.
Sign Out on Shared Computers
Use the session list after you finish. Closing a tab is not the same as ending a Telegram session.
