How to Log Out of Claude.ai | Sign Out of All Devices at Once

Claude.ai Has 3 Logout Paths

Understanding the full picture upfront will save you from getting lost. Claude.ai logout involves three distinct operations with different purposes.

1. Log out of only the device you are currently using — for a normal sign-out from your own PC or smartphone. In the settings screen, find the "Active sessions" section and exit the row labeled Current.
2. Sign out of all devices at once — for situations like forgetting to log out on a shared PC or suspecting unauthorized access. Use the "Log Out" button in the Account section of Settings to disconnect every device that is currently signed in.
3. Terminate a specific device's session — for when you want to keep using your current device but remove an old device's session. Find the device in the Active sessions list and choose Terminate.

You might think options 1 and 2 are the same, but they use different buttons. Option 1 signs you out of only the current device; option 2 signs you out of all devices including the current one. Confusing the two leads to either "I got signed out everywhere" or "the other device is still logged in," so decide your goal before you act.

How to Log Out on a PC Browser (This Device Only)

Here are the steps for the most common case: logging out of just your current device via a PC browser. This follows the flow described in the official help article "Managing your active sessions."

Step 1: Open the Profile Icon

With Claude.ai open, click the profile icon in the bottom-left corner (a circular icon showing your initials). This is the entry point to all Claude.ai settings.

Step 2: Go to Settings → Account

From the menu, select Settings, then navigate to the Account section.

Step 3: Scroll Down to Active Sessions

Scroll down the Account screen until you see the Active sessions section. This lists all devices currently signed in to your account.

Step 4: Log Out of the Current Session

Find the row labeled Current in the list, click the three-dot menu (⋮) on the right side, and choose "Log out." When a confirmation modal appears, confirm your choice. You will be logged out of this device.

The source for this procedure is the official help article "Managing your active sessions" (support.claude.com/en/articles/13124001-managing-your-active-sessions). Note that the three-dot menu contains both "Log out" and "Terminate" — see below for when to use each.

Important Notes for Logging Out on a Smartphone App (iOS / Android)

On the Claude mobile app, you also access logout through the profile icon in settings. Here are the steps to log out of the smartphone you are currently using.

1. Open the Claude app and tap the profile icon (circular icon with your initials).
2. Tap Settings from the menu.
3. Tap Log out in the settings menu.
4. Confirm when prompted. You are now logged out of this device.

However, there is an important limitation. According to the official Help Center, the "Log Out" button for signing out of all devices at once is not available in the iOS or Android mobile apps at this time.

This means if you want to sign out of all devices from your smartphone, you need to open claude.ai in a PC browser (or in your smartphone's browser with desktop view enabled). If you are using the app and cannot find a "sign out all" button, this is why. As a general rule, the app handles only signing out of that specific device.

How to Sign Out of All Devices at Once

Forgot to log out on a shared PC, left yourself logged in on a family member's or colleague's device, or worried about unauthorized access? The all-device sign-out is what you need. Here are the steps from the official help article "How do I log out of all active sessions?":

1. Open a web browser and sign in to claude.ai.
2. Click your initials (profile icon) in the bottom-left corner of the screen.
3. Select Settings from the menu.
4. Navigate to the Account section.
5. Click the "Log Out" button.
6. Confirm when prompted.

When you do this, as the official documentation states, you are "immediately signed out of all devices you were previously logged in on." Browsers, mobile devices, and desktop apps alike will all require you to authenticate again — either via Google login or an emailed login link — before you can use Claude.ai again.

Anthropic's official documentation notes this is "particularly useful if you forgot to log out on a shared device or if you suspect unauthorized access to your account." The source is "How do I log out of all active sessions?" (support.claude.com/en/articles/10310342-how-do-i-log-out-of-all-active-sessions). As noted above, this button is not available in the iOS / Android apps.

Signing Out of a Specific Device Only

If you want to keep using your current PC but remove an old laptop's session or a phone you no longer own, use individual Terminate rather than the all-devices log out.

1. Go to the profile icon in the bottom-left → Settings → Account.
2. Scroll down to Active sessions.
3. Find the row for the device you want to remove and click the three-dot menu (⋮) on the right.
4. Choose "Terminate" and confirm in the modal.

The official Help Center explicitly states that "once you end a session, that device will need to log in again to access your account." Your current device (labeled Current) remains active, so you can clean up unwanted sessions without interrupting your own work. This is also useful when you suspect a takeover but do not want to log out everywhere.

5 Reasons You May Be Getting Logged Out Unexpectedly

Many users report being signed out of Claude.ai without intentionally logging out. The causes are usually clear-cut — work through these in order.

1. Your browser is set to clear cookies and site data on exit — Browser privacy settings or extensions may be deleting Claude.ai login information every time you close the browser, forcing you to log in again each time. Add claude.ai to your browser's cookie exception list.
2. You are using a private or incognito window — These windows are designed to delete the session the moment you close them. If you use Claude.ai regularly, open it in a normal window.
3. Someone ran the "sign out of all devices" logout — If you or someone sharing your account pressed the Log Out button described above, every device gets signed out. If you suspect this, it is likely the cause.
4. You are switching between multiple accounts — Switching between a work account and a personal account (different email addresses) can make it appear as though you were logged out of one when you signed into the other.
5. VPN, browser extensions, or cache inconsistency — The official Help Center suggests "turn off your VPN," "disable extensions," and "clear cache and cookies" as first steps for login-related issues. If things work fine in a private window, the culprit is likely an extension or a cookie issue.

Also note that Claude.ai itself may be experiencing an outage. If behavior suddenly becomes erratic, check the Anthropic status page (status.anthropic.com) first to see whether it shows green. If you cannot sign in at all, see the separate article Claude AI Login Issues for a systematic troubleshooting guide.

What to Check Before Logging Out

Logging out does not delete your conversation history (chats). When you sign back in to the same account, all your previous threads will still be there. You can rest assured that logging out does not mean deleting your data.

What you should watch out for is text you have typed but not yet sent. If you run an all-devices sign-out or Terminate while you have a draft in the prompt field, that draft may not be saved. If you are in the middle of writing a long message, copy it somewhere safe before logging out. When leaving a shared PC, also check that no browser history or form input remains after you log out.

Logging Out of console.anthropic.com Is a Separate Matter

One last point that is easy to mix up. claude.ai — where you chat — and console.anthropic.com — the developer API management dashboard — may look similar, but they have separate account systems and separate login/logout flows. A lot of the confusion around "I'm logged into Claude but can't log out / can't get in" comes from mixing up these two.

You can tell which one you are on by looking at the URL in your browser's address bar. If it is claude.ai, you are on the chat interface; if it is console.anthropic.com, you are in the API and billing dashboard. All logout steps in this article apply to claude.ai only. To end a Console session, use the settings inside Console.

Frequently Asked Questions (FAQ)

Q. Does logging out delete my conversation history? A. No. When you sign back in to the same account, all your previous chats remain intact. Logging out ends your session — it does not delete your data.

Q. Can I sign out of all devices from the smartphone app? A. Not at this time. The "Log Out" button for signing out of all devices is not available in the iOS or Android apps. Open claude.ai in a PC browser or your smartphone's browser to perform this action.

Q. I forgot to log out on a shared PC. Can I sign out now? A. Yes. Sign in to claude.ai from your own device, then use the "Log Out" button under Settings → Account to sign out of all devices at once — this will also end the session on the shared PC.

Q. Do I need my password to log out? A. Claude.ai uses Google login or an emailed login link for authentication — not a password. The logout operation itself is done from within a signed-in session, so no password entry is required at that point.

Logging out of Claude.ai comes down to three paths: "this device only," "all devices," or "a specific device." For everyday use, sign out from Current in Active sessions. When you need to clear a shared device or have security concerns, use the Log Out button in Account. All the controls are in one place: profile icon → Settings → Account — so start there and you will find what you need.
