My messanger says my password is wrong - Yahoo Messenger

If you gave him your password and your username for your email account or for your messenger account then he can log in to your account and change the password to one only he knows. If he can get into your email he can read all your old emails. If you use the same password for multiple accounts, he can keep guessing at what accounts you might have and try the password. Even if you have accounts that don't use the same password but use your email address to log into, he can try to log into those with your email address and say he doesn't remember your password and they'll email him a new one.
Sounds like you're screwed. Call your ISP (Internet service provider)

i have problem in yahoo messanger signing, my email is opening but messanger not logged in. i also change password but still same problem, from the same messanger i logged on another id but it work and only my id is not working.

maybe the caps lock is on because password is case sensitive or a certain key in your keyboard has a problem.
