Why logging out matters, and when you should do it
Logging out closes your active session on a website or app, which means someone else using that device cannot access your account without your password. It is not the same as closing the browser or app — those just hide the window, but your session often stays open in the background.
You should log out on shared devices (computers at a library, a family tablet, a work computer you share), on public Wi-Fi networks, and after using sensitive accounts like email or banking. On your personal device that only you use, logging out is less critical, but it is still a good habit — it limits the window of time an attacker would have if your device is stolen or compromised.
The steps to log out vary by service, but the pattern is almost always the same: find your account menu, look for a "Log Out" or "Sign Out" button, and click it. What changes is where that button lives.
Key Takeaways
- Logging out closes your session so the next person using that device cannot access your account without your password.
- Always log out on shared devices, public computers, and public Wi-Fi networks; on your personal device it is less critical but still a good practice.
- The log-out button is usually in a menu tied to your profile picture, name, or account icon — not in the main navigation.
- Closing the browser or app does not log you out; your session often stays active until you explicitly sign out.
- If you cannot find a log-out option, check the account settings or help section for that specific service.
Where the log-out button usually is
On most websites and apps, the log-out button is hidden in a menu tied to your profile. Look for a small circle with your initial, your profile picture, or your name in the top right corner of the page (on desktop) or in the top left or bottom of the screen (on mobile apps). Tap or click it.
A menu will drop down or slide out. You are looking for "Log Out", "Sign Out", "Logout", or sometimes "Exit". Click that option. You will usually be sent back to the login page or the home page, and your session is now closed.
If you do not see a profile menu, check the main navigation menu (the three horizontal lines, called a hamburger menu, on mobile). Some apps hide account options there instead. If you still cannot find it, look in Settings or Account Settings — most services put a log-out option somewhere in account management.
Logging out on specific platforms
Gmail and Google services: Click your profile picture in the top right. Select "Sign out". You will be logged out of Gmail and most other Google services at once (YouTube, Google Drive, Google Maps, etc.).
Facebook: Click the downward arrow in the top right corner. Select "Log Out" from the menu.
Instagram: On mobile, tap the profile icon at the bottom right, then tap the menu icon (three horizontal lines) in the top right. Scroll down and tap "Log Out". On desktop, click your profile picture in the top right, then click "Log Out".
Twitter/X: Click "More" (three dots) in the left sidebar. Scroll down and select "Log Out".
Microsoft/Outlook: Click your profile picture in the top right. Select "Sign out".
Amazon: Hover over "Account & Lists" in the top right. Click "Sign Out".
Banking apps: Look for a menu icon (usually three lines or dots). Find "Sign Out", "Log Out", or "Exit". Some banking apps also let you log out by going to Settings or Account.
What happens after you log out
Once you log out, your session is closed. The next person who opens that browser or app will see the login page, not your account. They cannot see your messages, posts, payment methods, or personal information without entering your password.
You will need to log back in the next time you want to use that account. If you saved your password in the browser, you may see your username pre-filled, but you will still need to enter your password (or use biometric login like a fingerprint if the service offers it).
Logging out on shared devices versus personal devices
On a shared device — a family computer, a work computer, a library computer, or a friend's phone — always log out before you leave. This is the most important security habit. Even if you trust the person, their device could be compromised, or someone else could use it later.
On your personal device that only you use, logging out is less urgent. Your main risk is if the device is stolen or hacked. If that happens, an attacker would have access to any accounts you are logged into. Logging out regularly reduces that window of risk, but it is not as critical as on a shared device.
A middle ground: log out of sensitive accounts (email, banking, social media) even on your personal device, but stay logged into less sensitive ones (news sites, shopping sites where you have saved payment methods). This is a personal choice based on how much you value convenience versus security.
If you cannot find the log-out button
Some services make log-out harder to find than others. If you have looked in the profile menu and the main navigation and still cannot find it, try these steps:
- Look in Settings or Account Settings. This is usually a gear icon or a link at the bottom of the menu.
- Search the help or support section of the site for "how to log out" or "sign out".
- On mobile, check if there is a Settings app separate from the main app — some services put account options there.
- If the service has a web version and a mobile app, try the other one. Sometimes log-out is easier to find in one or the other.
If you still cannot find a log-out option, you can force a logout by clearing your browser cookies or app data for that service. On most browsers, you can right-click the site in your history, select "Forget About This Site", and your session will be closed. On mobile apps, go to Settings, find the app, and select "Clear Cache" or "Clear Data" (this will also delete saved preferences, so use it as a last resort).
Staying logged in: when it is safe and when it is not
Many services offer a "Keep me logged in" or "Remember me" checkbox at login. This is safe on your personal device, but never use it on a shared device. Even if you trust the person, it means they can access your account without a password.
On public Wi-Fi, staying logged in is riskier because someone on the same network could intercept your session. If you must use public Wi-Fi, log out when you are done and do not use the "Keep me logged in" option.
If a service automatically logs you out after a period of inactivity (common with banking and email), that is a security feature, not a bug. It protects you if you forget to log out.
Frequently Asked Questions
Does closing the browser tab log me out?
No. Closing the tab or browser does not end your session. Your login cookie stays on your device, and the next time you visit that site, you will still be logged in. You must click the log-out button to actually end the session.
What if I log out and then realize I forgot to do something in my account?
Just log back in. There is no penalty for logging out and back in multiple times. If you are on a shared device, this is actually the safer choice — log out, then log back in only when you need to use the account.
Can someone log into my account if I do not log out?
Not without your password, unless they are using the same device while you are still logged in. If you are logged in and someone else uses that device, they can see and do anything in your account. This is why logging out on shared devices is important.
Does logging out delete my saved passwords?
No. Logging out only closes your session. Your saved passwords stay in your browser or password manager. The next time you log in, you can use those saved credentials (or enter your password manually).
What if a website does not have a log-out button?
This is rare but happens with some older or poorly designed sites. If you cannot find a log-out option anywhere, clear your browser cookies for that site, or use your browser's "Forget About This Site" option. On mobile, uninstall and reinstall the app, or clear the app's cache in Settings.
