Answer 1

Mostly, when we install the Magento Community on our local computer (XAMPP, WAMPP), it looks like we can't log in as the administrator from the backend. The system will prompt us we input the wrong password, but it's not the truth.

When i come up with this issue, i tried to reset the password by following method (in SQLyog).

UPDATE admin_user 
SET password=CONCAT(MD5('qXpassword'), ':qX') 
WHERE username='admin';

‘password’ should be set to whatever you want for your new password, and ‘qX’ would be any random characters you like.

But we still can not log in. At first, I thought this method is wrong method. While, the 'admin' password definitely had been changed. But why we still can not log in?

Maybe we have input the right user name and password, but we still can't log in.

Use Notepad ++ to open and edit core file: app/code/core/Mage/Core/Model/Session/Abstract/Varien.php, within your magento directory and comment those below lines:

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

And try again, you should can log in as admin from the backend.

The problem is Localhost or "127.0.0.1" are not true domains, and browsers allow only real domains to store cookies, that's why login stops and with invalid Username or Password.
