It's not unusual to type in an incorrect username or password when logging into phpMyAdmin.
However, a failed login can sometimes lead to a frustrating experience: When you immediately attempt another login with the correct username/password, it will fail. It will continue to fail, no matter how many times you enter the correct user/pass combo.
This happens because of session-handling inconsistencies between phpMyAdmin and your browser.
If you ever encounter this issue, here is an easy solution:
Right after a failed login attempt using correct credentials:
- Hold down the shift key on your keyboard.
- Click the "reload" button on your browser.
This will refresh the session and re-send your login credentials. If the credentials are correct, your phpMyAdmin dashboard should appear. For more information on clearing your browser's cache, please read: Clearing your browser's cache.
