my info. I know i'm using the correct ID and password but it keeps telling me it's invalid. It's happening with yahoo and ebay and I've had both these accounts for at least 4 years now with no problems whatsoever. What's wrong?

THanks in ADVANCE!!I think I would use the PROCEDURE for a forgotten password and reset your password once you get back into your account.That's the problem it won't accept my login ID or my password. I TRIED to sign up with a new account using my current login info and it says that account is taken already. I thought it was just a problem with yahoo until my Ebay starting acting the same way. Now I'm wondering if it's a computer virus or something.Well, try using another computer to login.  That will quickly answer the issue of whether it has something to do with your computer.  Do you have other online accounts (bank, credit card, etc.) that require secure logon?  Can you logon to them?  

Since this involves your eBay account, I think you should resolve this as soon as possible if you have a Paypal or any other financial account linked to it.  Also, you should closely monitor any financial accounts linked to your eBay account; might also be a good idea to notifiy any affected financial accounts of this situation to limit your liability in case any unauthorized transactions are charged to your account(s).

This situation may be also be indication you need to improve your password security in the future.  Hmmmm, it won't let me in on another computer either... So are you thinking that someone jacked my info and then changed my passwords??Yes, I think you should assume that might have happened.  Perhaps you should visit eBay's Security & Resolution Center.  
      How would this have happened??? We don't allow anyone..and I mean anyone on our computer so how would someone have found my info??

I looked up my user id on ebay and it says I'm from CA... I'm in TX not CA someone has changed everything about my account except for my login id. This sucks!Did you use a "STRONG" password, one with numeric and symbol characters, along with letters?  How long did you use the same password?  Using passwords based on the names of spouses, children, pets, etc., especially without numeric and symbol characters, results in passwords that are not too difficult, for someone who knows you, to guess.Did you respond to an email from eBay (supposedly) that asked you to VERIFY your information? If you login through a "phishing" link, your information is private no more.

If you have a PayPal account I would check that pronto also!
