Hi, that error occurs only when you signed in or log in to another computer or device. There must have been someone who knows your password and e-mail address. Please change your password for security purposes. To change your password please follow this instruction:
1. Sign in on your account then click on your "yahoo id" then hit on "account info" as shown below.

2. Under "Sign in and Security" tab. please click on "change your password". eibraz_20.jpg 3. Change your password and then save. i hope this helps.

The yahoo messenger says I've been disconnected because I've signd in from another computer or device, but i havn't. how do i find out what device or computer?

It means that somebody has access into your account..when you are currently on line and this message appears ( I've been disconnected because i've signed in from another computer or device) somebody is also signing in your account in another computer. The best thing for you to do is change your password.

Messenger keeps telling me i am signed in on another device. there 4 signes me out.

This means that you just might have opened your email and appeared there as "online". So just change your status on your email to "Offline". This should fix your problem.

Please let me know if this helps. Thank you for using FixYa.

Can't stay signed-in to YM, always getting disconnected

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.
