How to Use Telegram Web: Login, Versions, and Security

Telegram itself positions the web version as a quick way to get things done on the go, alongside its native apps for phones, tablets, and desktops. You still need an existing Telegram account, which is created with a phone number on a mobile app, and you can stay logged in on as many devices as you like at the same time. If you are entirely new to the platform, start with our complete guide to using Telegram first, then come back here for the browser workflow.

The web client shines in situations where installing software is impractical: a locked-down office computer, a school library terminal, or a borrowed laptop. It is also a light-footprint option if you simply prefer to keep fewer applications installed. For heavy daily use with the fullest feature set, the native app remains the stronger choice, and our Telegram Desktop download guide covers that path.

When you open web.telegram.org, the login screen offers two routes: scanning a QR code with the Telegram app on your phone, or signing in with your phone number. The QR method is usually faster because you never have to wait for a code to arrive.

Prefer the phone-number route? Click 'Log in by phone number', enter your number, and type the login code Telegram sends to your active app session. If you have Two-Step Verification enabled, you will also enter your account password before the session opens; that extra password is exactly what protects your account when someone else has your SMS code. If the code never arrives, see our troubleshooting guide for not receiving your Telegram login code.

Once you are signed in, independent guides consistently report that the browser session talks to Telegram's cloud on its own, so your phone does not need to stay online for the web client to keep working. Telegram's own cookie disclosure is also worth knowing: the service states it only uses cookies needed to operate the web app, and blocking those cookies will prevent you from logging in at all.

Telegram unusually maintains two official web clients side by side, and its applications directory lists both: Telegram Web Version K and Telegram Web Version A. Both are open-source projects under GPL v3, and both grew out of Telegram's efforts to keep the browser experience competitive with its native apps.

You can switch between versions from the client's main menu, which offers an option such as 'Switch to K Version' or the equivalent link back to Version A. Feature sets shift with every release, so if something seems missing in one version, trying the other is a legitimate first troubleshooting step. One area where published sources genuinely disagree is calling: some guides state that voice and video calls are unavailable on the web, while others, along with Web A's own changelog entries about group calls, indicate call features exist in at least some versions. Treat call support as version-dependent and changeable, and rely on a native app when a call absolutely has to work.

That distinction matters for how you use the web client. Routine conversations, group coordination, and channel reading are well within its comfort zone. For conversations that genuinely require end-to-end encryption, use a Secret Chat on your phone instead of the browser, and read our deeper analysis of whether Telegram is safe for the full picture of Telegram's encryption model.

Every login, including each browser session, appears in Telegram's Active Sessions list, which Telegram introduced precisely so users can spot and close forgotten or suspicious logins. On your phone, open Settings, then Devices, to see each session with its device and connection details, and terminate any session remotely with one tap. Enabling Two-Step Verification adds an account password on top of login codes, which sharply raises the bar against account takeover from a new device.

The browser client's biggest convenience, working on any computer, is also its biggest risk surface. Institutional security guidance for public and shared computers, such as the United Nations OICT safety tips, is directly applicable: avoid entering sensitive information on machines you do not control, never rely on 'keep me signed in', and assume that anyone using the computer after you will try what you left behind.

Also make sure you are on the genuine site. Only ever sign in at web.telegram.org; lookalike domains that imitate the Telegram Web login screen are a phishing vector, and the QR-plus-confirmation design only protects you if the code you scan is really Telegram's.

Desktop notifications from Telegram Web work through the standard web Notifications API: the site must ask, and you must explicitly allow the web.telegram.org origin to show system notifications. If alerts are not appearing, check your browser's site settings; in Chrome this lives under Privacy and security, Site Settings, Notifications, where you can allow or block individual sites. Note that Chrome does not deliver site notifications at all during Incognito sessions, so a private-browsing Telegram session will stay silent by design.

Media handling is one of the web client's strengths: you can view photos, stream videos, and share files backed by Telegram's cloud storage, in the same account and chats you use everywhere else. If you want to save media for offline use, the first rule is authorization: only download content you own, created, or have clear permission to keep.
