The fastest way to log out depends on what you're using

On a computer, click your profile picture or initial in the top right corner of Yahoo Mail, then select "Sign out" from the menu that appears. On a phone or tablet, tap the menu icon (three horizontal lines) in the top left, scroll down, and tap "Sign out". If you're on a shared device, always log out before walking away — it takes five seconds and keeps your email secure.

If you can't find the sign-out button or you're locked out of your account, you may need to clear your browser's stored passwords or reset your password through Yahoo's account recovery page. The steps differ slightly depending on whether you use Yahoo Mail through a web browser, the Yahoo Mail app, or a third-party email client like Outlook or Apple Mail.

Key Takeaways

  • On a web browser, click your profile picture in the top right corner and select "Sign out" from the dropdown menu.
  • On the Yahoo Mail mobile app, tap the menu icon (three lines) in the top left, scroll to the bottom, and tap "Sign out".
  • Always log out on shared computers, public devices, or borrowed phones to prevent others from reading your email.
  • If the sign-out button is missing or unresponsive, try clearing your browser cache or restarting the app before trying again.

Logging out on a web browser

Open Yahoo Mail in your browser and look for your profile picture or the first letter of your name in the top right corner of the screen. Click it once. A small menu will drop down with several options, including "Sign out" or "Log out" — the exact wording varies depending on which version of Yahoo Mail you're seeing.

Click "Sign out". You'll be taken to the Yahoo login page, which confirms you've been logged out. If you want to be extra cautious on a shared computer, close the browser window entirely after logging out. This prevents the browser from automatically logging you back in if someone opens Yahoo Mail again.

Logging out on the Yahoo Mail app for iPhone or Android

Open the Yahoo Mail app and tap the menu icon — three horizontal lines stacked on top of each other — usually in the top left corner. Scroll all the way to the bottom of the menu. You'll see "Sign out" or "Log out" as one of the last options.

Tap it. The app will return to the login screen, confirming you're logged out. If you have multiple Yahoo accounts set up in the app, signing out of one account logs you out of all of them. If you want to keep one account active, you'll need to remove the others from the app instead of signing out completely.

Logging out when Yahoo Mail is connected to Outlook, Apple Mail, or Gmail

If you've set up Yahoo Mail to work inside Outlook, Apple Mail, or the Gmail app using a password or app-specific password, logging out of Yahoo Mail's website won't disconnect it from those apps. You need to remove the account from the app itself.

In Outlook on Windows, go to File > Account Settings > Account Settings, find your Yahoo account, select it, and click "Remove". On a Mac, open Mail > Settings > Accounts, select your Yahoo account, and click the minus button. In Apple Mail on iPhone or iPad, go to Settings > Mail > Accounts, tap your Yahoo account, and select "Delete Account". In the Gmail app, tap your profile picture, select "Manage your Google Account", go to Security, scroll to "Your devices", find the connected Yahoo account, and remove it.

What to do if the sign-out button isn't working

If you click the sign-out button and nothing happens, or if the menu doesn't appear, try refreshing the page. Press Ctrl+R on Windows or Command+R on Mac. Wait a few seconds for the page to reload, then try clicking your profile picture again.

If that doesn't work, clear your browser's cache and cookies. In Chrome, press Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac), select "All time" from the time range, check "Cookies and other site data", and click "Clear data". Close the browser completely and reopen it. Go back to Yahoo Mail — you should be logged out. If you're still logged in, you may need to reset your Yahoo password to fully secure your account.

Logging out on a public or shared computer

Public computers at libraries, schools, or internet cafes should always be logged out of before you leave. After you sign out, don't just close the browser — open a new tab and navigate to a different website to make sure the logout took effect. Some public computers have automatic logout features that sign you out after a period of inactivity, but don't rely on that.

If you borrowed someone else's device, ask them to show you where the sign-out button is if you can't find it. Some older versions of Yahoo Mail or devices with accessibility settings may have the menu in a slightly different location. After you sign out, let the owner know you've done so.

Staying logged in on your own device

If you're on your own computer or phone and you want to stay logged in, you don't need to sign out every time. Yahoo Mail will keep you logged in until your session expires (usually after several weeks of inactivity) or until you manually sign out. Closing the browser or app doesn't log you out — it just closes the window.

If you share your device with family members or roommates, consider using your browser's profile or user account feature instead. Chrome, Firefox, Safari, and Edge all allow multiple user profiles on the same device, each with separate login information and browsing history. This way, each person can have their own Yahoo Mail account without needing to log in and out constantly.

Frequently Asked Questions

Does closing Yahoo Mail log me out?

No. Closing the browser tab, closing the app, or shutting down your device does not log you out. Yahoo Mail keeps you logged in until you manually sign out or your session expires after weeks of inactivity. Always click the sign-out button if you want to end your session immediately.

What if I forgot my password and can't log out?

You don't need your password to log out. Click your profile picture and select "Sign out" — this works whether you remember your password or not. If the sign-out button isn't responding, clear your browser cache and try again, or restart the Yahoo Mail app.

Can someone log back into my account if I don't sign out?

On a device only you use, no — they would need your password. On a shared device, yes. Anyone with access to that computer or phone can open Yahoo Mail and read your email if you're still logged in. Always sign out on shared devices before leaving.

Will signing out delete my emails?

No. Signing out only ends your session. Your emails stay in your Yahoo Mail account and will be there the next time you log in with your password. Signing out does not delete, archive, or change any of your messages.

How do I log out of Yahoo Mail on all devices at once?

You can't log out of all devices from one button, but you can force a logout by changing your Yahoo password. Go to your Yahoo Account Security page, select "Change password", and create a new one. This logs you out everywhere and requires you to enter the new password the next time you sign in on any device.
