^_^ weeeeell lets see here.\n\nYou have two main options. One\nis to use Javascript (Look below) and\nTwo, to use PHP.\n\n\n This is an example of javascript that will prompt the\nuser for their user name and password before they can\naccess the page. Just put this in the header of your page.\n\n<script language="Javascript" type="text/javascript">\nname = prompt("User name");\npass = prompt("User Password");\n\nif(name == "joe" && pass == "shmoe"){\nwindow.location =   "www.ProtectedpageURL.com";\n}else{\nalert("Incorrect password");\nwindow.location = "www.invalidInfoPage.com"\n}\n</script>\n\nRemember, javascript can be seen in your source so have them\nclick a link to goto the page with this code, and the redirect on\ncorrect or incorrect information will keep them from ever\nbeing able to access the page and see the source where your\naccount information will be held. \n\n\nIf you have PHP enabled on your website then email me\nat void_3e01@yahoo.com and I will be more than happy to\nmake you a complete, fool proof login script.\n\n -Void

Don't worry.\nOpen Yahoo page.\nUnder the sign-in box you can see 'Forget your ID or password?'.\nClick it.\nThen confirm your identity.\nThat's all.\nHave a great days.

Try to restart your browser or your whole computer, also check your email for an activation email and it will automatically log you in  as you activate it through a link. Or write to yahoo's techinal department

try the same version with different set of username and password; if it works then the username and password was not correct. If it doesnt work try with a different computer connected to the same Networking Device(router or switch or modem). If it also fails check the port used by yahooo messenger.

Assuming you are clicking the "Save my login info" checkbox when you sign in, you probably aren't saving cookies.  To enable cookies, go to the "Options" item under the Tools menu.  Then look at the "Cookies" tab under the Privacy section and make sure you haven't disabled cookies.\n\nI usually have "allow sites", "originating site only" and "keep til they expire".  If it still isn't working, check your exceptions to make sure you haven't specified yahoo.com can't set cookies.

sounds like that is a password protected page. I always thought the 404 error meant the page cant be found.

Not even sure what you mean...how are you loggin in and did you try and request a new password? this would tell you if your username even exists

make sure that for a user name you are not entering your email address. If you enter <username>@yahoo.com, it thinks you are trying to login to the domain yahoo.com and will fail.

click the "forgot your yahoo id or password" link just below the login.
