Sometimes when i sign in to yahoo mail or gmail, i get a message saying i have been signed out because i have signed in on another computer. have my emails been hacked?

Point your web browser at http://www.gmail.com

If another account comes up, sign out of it by clicking the avatar in the upper-right then clicking "Sign out."

If you then still can't sign in to your account, click the "Need help?" link on the sign-in page.

If you're getting an error message, what does it say?

Signing in to your Gmail account gives you access to your email messages.
Gmail Web-based email functions as most email services do, with the option for users to send and receive email messages, store contacts and organize messages.
You can opt to store your Gmail login information when signing in so that you do not need to re-enter it each time you access your email.You can access your Gmail account on a computer or a mobile phone.

Open a Web browser window.
Click the address bar and enter "gmail.com." Press the "Enter" key.

Enter your Gmail username and password in the indicated fields.
Check the "Stay Signed In" box to save your username and password for future logins.
Click "Sign In" and wait for your Gmail account to load.
Mobile Phone
Press the "Menu" key on your mobile phone and click the "Browser" icon.
Click the Web address bar and enter "gmail.com."
Enter your Gmail username and password and click "Sign In."

simply use your address and password. Sometimes there is a box on the sign in screen that says sign in as different user. Either way you can still sign in.
Hope it helps

• Check your Messenger is Sign in at the Time of Sign in to Yahoo mail

• Sign out from Mobile/any other Device

Yahoo has prevented us from having 2 Instant Messaging capable programs open and active at the same time.
For example, Yahoo Messenger with Yahoo Mail or Yahoo Web messenger, your mobile phone, Ipod, or other computers etc. etc.
Yahoo classifies all these programs as "Different devices or locations". Navigating from one to the other will close one program and you may get the notification message you refer to.
OR someone has hacked into your account- Report to Yahoo and Try to Recover it-Send report Politely and concisely.Do not try to Send More report for Same cause..

You can only have one yahoo "Instant message capable" program open at one time. So if you move from Messenger to mail or chat you will get this message. If you want to have Yahoo Mail open with another Yahoo IM program you will have to set your status to "offline" in MAIL by using the dropbox next to your name ( all new mail) select "sign out of chat"
In Classic mail its located in the Inbox. Your online chat contacts will vacate the inbox until you make yourself "Available" again.
Yahoo classifies - Messenger - Mail - webmessenger - my yahoo - mobile phones - computers etc etc as different computers or devices - hence the confusion.

sound like you check;
Keep me signed in
for 2 weeks unless I sign out. Info

Then select I can't access to my account

When you sign into Mail first, the new Yahoo mail automatically signs you into messenger. Mine did that all the time so now I sign into Yahoo Messenger first then when it tells me I have mail, I click on the envelope and it takes me to my mail account without signing me out of messenger. I hope that helps you.

check your username and password. also, check your cookie setting (security settings under options) if using internet explorer. try to download mozilla firefox and see if you can sign in with that web browser. www.mozilla.org signed, Doctor MyPC [email protected]
