You usually do not need to log out of Telegram just to use it on another device. Telegram supports multi-device use, so most people can stay signed in on phone and computer at the same time.

But if you do want to log out, the path is simple. Telegram's FAQ says:

  • on iPhone: Settings -> Edit -> Log out
  • on Android and Telegram Desktop: Settings -> ... -> Log out

If your problem is an old or lost device, the better move is usually to terminate that session remotely instead of logging out everywhere manually.

Quick answer by device

Device Fastest path
iPhone Settings -> Edit -> Log out
Android Settings -> ... -> Log out
Telegram Desktop Settings -> ... -> Log out
Telegram Web Open menu or Settings, then choose Log out
Lost or old device Settings -> Devices or Privacy & Security -> Active Sessions, then terminate the old session

Before you log out

Telegram's FAQ says logging out keeps your cloud messages, but there is one important tradeoff:

  • you keep your cloud chats
  • you lose all Secret Chats on that device
  • logging out does not delete your account
  • logging out does not uninstall the app

Telegram also warns that logging out does not remotely erase secret chat messages from the other person's device.

That is why logging out and deleting your account are not the same thing. If you want to remove the account completely, use How to Deactivate Telegram Account.

How to log out of Telegram on iPhone

Telegram's FAQ gives the iPhone path directly:

Settings -> Edit -> Log out

That is the cleanest answer if you are using Telegram on iOS and just want to sign out from the app on that device.

How to log out of Telegram on Android

Telegram's FAQ says the Android path is:

Settings -> ... -> Log out

Depending on the app version, the three-dot menu may sit in a slightly different place, but the logout action still lives in the settings area rather than somewhere hidden in the phone's system settings.

How to log out of Telegram Desktop

Telegram's FAQ groups Telegram Desktop with Android for the logout path:

Settings -> ... -> Log out

If your real goal is to clear a session from a shared computer, logging out is enough.

If your goal is to save local space on your own machine, Telegram says clearing cache is often better than logging out:

Settings -> Data and Storage -> Storage Usage -> Clear cache

How to log out of Telegram Web

Telegram Web can vary a little between WebA and WebK, but the practical path is:

  1. Open the main menu.
  2. Open Settings.
  3. Choose Log out.

If you are on a borrowed or public computer, do not leave the browser session active when you finish.

If you are not sure whether the session is still open somewhere, remove it remotely from another device using the active sessions flow below.

How to log out remotely from another device

If you lost a phone, changed computers, or forgot to log out on another machine, this is the most important section.

Telegram's FAQ says to go to:

Settings -> Devices

or:

Privacy & Security -> Active Sessions

From there, terminate the session on the device you no longer trust.

This is often better than logging out of your current phone because it targets the risky device directly.

What to do if your phone was lost or stolen

Telegram's FAQ gives a very specific order here.

If you still have access to Telegram on another device:

  1. Turn on two-step verification.
  2. Open Settings -> Devices or Privacy & Security -> Active Sessions.
  3. Terminate the old phone's session.
  4. Contact your carrier to block the old SIM and reissue your number.

If you do not have access on any other device:

  1. Recover your number from your carrier first.
  2. Log back in with that number.
  3. Terminate the old session.

If you are also moving to a new phone, use Transferring Telegram to a New Device.

What logout does not do

This is where users often get confused.

Logging out does not:

  • delete your Telegram account
  • delete your cloud message history
  • remove the app from your device
  • erase the other person's copy of a Secret Chat

If your goal is privacy rather than device cleanup, you may also want to review Telegram privacy settings.

When not to log out

Telegram's FAQ says most users do not need to log out.

That is true when:

  • you want to use Telegram on more than one device
  • you just need to free up space and can clear cache instead
  • you use more than one phone number and can switch accounts instead

In those cases, logging out creates extra friction without solving the real problem.

FAQ

Can I log out of Telegram on all devices at once?

The most practical way is to open Settings -> Devices or Privacy & Security -> Active Sessions and terminate the sessions you no longer want.

Will I lose my messages if I log out?

Your cloud chats stay. Secret Chats on that device do not.

What if I lost my phone?

If you still have Telegram on another device, terminate the old session there and secure the account with two-step verification. If not, recover the phone number first, then log in and remove the old device.

Should I log out or delete my account?

Log out if you only want to stop using Telegram on a device. Delete the account only if you want to remove the account itself. For that path, use How to Deactivate Telegram Account.

Final answer

The cleanest answer is simple: use Settings -> Edit -> Log out on iPhone, Settings -> ... -> Log out on Android and Desktop, and the menu/settings logout option on Telegram Web.

If you lost a device, do not stop at local logout. Go straight to Settings -> Devices or Active Sessions and terminate the risky session remotely.
