you can login to phpmyadmin, search for "admin_user" field & click on that and choose MD5 and give new password & save it.

step 1 : Login to Phpmyadmin & select proper database

Answer 2

This types of problems occures when magento fails to get domain(mainly in case of localhost). During login magento tries to create cookie. You can wether cookies are forming or not from your web browser. If it is not forming then you have to make some changes in varien.php file.

Find the following file. app\code\local\Mage\Core\Model\Session\Abstract\Varien.php

and overide it in local(make required folders if not there). Then find

if (isset($cookieParams['domain'])) {
$cookieParams['domain'] = $cookie->getDomain();
}

Simply change the condition to

if (isset($cookieParams['domain']) && !in_array("127.0.0.1", self::getValidatorData())) {
$cookieParams['domain'] = $cookie->getDomain();
}

main reason of doing so is to disable domain check if running on localhost.

I had fixed the above issue by following these steps.

1- Go to file app/code/core/Mage/Core/Model/session/abstract/varien.php

2- Go to line number 95 and comment out the cookieParams array and define $cookieParams as an array like below

// session cookie params
/*$cookieParams = array(
    'lifetime' => $cookie->getLifetime(),
    'path'     => $cookie->getPath(),
    'domain'   => $cookie->getConfigDomain(),
    'secure'   => $cookie->isSecure(),
    'httponly' => $cookie->getHttponly()
);*/
$cookieParams = array();

This will allow you to log in. 3- Then go to admin panel check configuration, System->Configuration->web->session & cookie management in that the HTTP control set from Yes to No. Clear or set the proper path.

Hope this answer will help you.
