How to Terminate Every Telegram Session and Lock Down Your Account

One action does it: Settings → Devices → Terminate All Other Sessions. Every phone, tablet, computer and web session other than the one you're tapping from is disconnected immediately.

The device you're using stays logged in — signing out there is a separate step. Here's both, plus how to tell whose session you're actually looking at in the list.

Terminating all other sessions

Android

1. Open the side menu (three lines) → Settings.
2. Go to Devices.
3. Tap Terminate All Other Sessions and confirm.

iPhone

1. Open the Settings tab at the bottom of the screen.
2. Choose Devices.
3. Tap the terminate-all button and confirm.

Computer

In Telegram Desktop open the menu → Settings → Privacy and Security → Active Sessions. The option to end all other connections lives there too.

It takes effect instantly: the disconnected devices return to the phone-number screen and their local data is wiped.

What terminating a session actually does

• Disconnects the device from the account. Logging back in needs the number and a confirmation code.
• Erases local data on that device, secret chats included — they aren't stored in the cloud and can't be recovered.
• Leaves cloud conversations untouched. Regular chats, channels and files stay put and reappear at the next login.
• Doesn't change your password. If you suspect someone else got in, the cloud password has to be changed separately.

Logging out on your current device

• Android: Settings → three dots in the top-right corner → Log Out.
• iPhone: open Settings and tap Edit in the top-right corner — the log out option appears.
• Computer: the client's settings have their own log out button.

If you keep several profiles, logging out affects only the active one — the rest stay in the app. To simply move between them you don't need to log out at all: use the profile menu.

How to read the device list

Every session under Devices shows the app and platform, the device model, an approximate location by IP, and the time of last activity. It's worth reading carefully before you tap anything.

Signs of an unfamiliar login:

• a device or client you don't use — unofficial apps especially;
• a city or country you haven't been in;
• activity at hours when you definitely weren't online;
• a web session you never opened.

An individual session ends by tapping it — handy when you want to disconnect one computer and leave the rest alone. In recent versions the session card also lets you limit its rights, for example blocking calls and secret chats.

Auto-terminating old sessions

The same section has a setting that closes inactive connections on its own, with intervals from a week to six months. Useful if you've logged in from other people's computers and can't remember whether you signed out.

One month suits most people: forgotten sessions close themselves while your everyday devices stay active.

Connected websites and bots

Besides apps, third-party services you signed into via Telegram may be attached to your account. They live in a separate list — Privacy and Security → Connected Websites — and terminating app sessions doesn't touch them.

If you're cleaning up your security, review that list too: sites you no longer use are better disconnected.

If your phone is lost or stolen

1. Log into the account from any other device using your number and a code.
2. Open Devices immediately and terminate all other sessions.
3. Set or change the cloud password so a code alone is no longer enough to get in.
4. Check connected websites and disconnect anything unnecessary.
5. Block the SIM with your carrier if needed — the confirmation code goes to it.

If you've only just logged in on a new device, Telegram may not let you terminate other sessions right away — that's a protective delay, and you'll have to wait it out.

If an account was handed to you

When a profile comes from someone else — along with a channel or a line of work, say — terminating the old sessions is the first mandatory step, not a suggestion. While those connections stay active, the previous owner keeps full access to the conversations.

The sequence is simple: log in, end all other sessions, set your own cloud password with a recovery email, and check the attached number. This applies to any transferred profile, including Telegram accounts obtained for a specific project — without those three steps, the account isn't really yours.

Common mistakes

• Terminating sessions without changing the password. If an outsider knows the cloud password, they'll simply log back in.
• Deleting the app instead of logging out. The session stays active on the servers and access remains.
• Ignoring web sessions. A forgotten browser tab is full access to your conversations.
• Panicking over an unfamiliar city. Location comes from the IP and often shows a carrier node rather than your actual address.
• Logging out instead of switching profiles. Local data is wiped and secret chats are lost for good.

FAQ

Will I lose my conversations after terminating all sessions?

No. Cloud chats, channels and files survive and load again at the next login. Only secret chats on the disconnected devices disappear.

Is the device notified that its session ended?

There's no separate message: the app there simply returns to the login screen.

Can I terminate a session without access to the account?

No. Device management works only from inside the account, so you have to log in on some available device first.

Why is the terminate button unavailable?

Usually it's the protective delay applied to a freshly created session. Wait and try again.

What can someone see in a session I haven't terminated?

Everything you can: cloud conversations, channels, files, and the ability to send messages as you.

Does changing my number cut off access?

No. Active sessions keep working — they have to be terminated separately.

How do I tell whether someone has been in my account?

Check the last activity times and the device list. An unfamiliar client or unexpected activity is reason enough to terminate everything and change the password.

In short

Every other connection closes with one button under Devices, and your current device signs out through a separate log out option. Your conversations aren't lost — they live in the cloud. And if suspicion of unauthorized access is what brought you here, terminating sessions alone isn't enough: set a cloud password with a recovery email right away and review the connected websites list.
