Hi I have had login issues for months which has result in being unable to use the chrome extension tool.

Password is the same as Ebay P/W. Can log into ebay but not myibidder either through the web page or via the ebay extension button to snipe an item.

Finally found your change password page on your website and changed it to reflect my ebay password. Again, unable to log in.

Can you help?

I'm not sure what you changed. You said the password is the same, but you changed the password after that.
You just need to login to the sniper using it, it will sync it automatically.

If you still need the help with it, please provide your eBay user id.
