HBW Alive allows you to enter an incorrect combination of username and password up to 5 times in a row. After the fifth attempt, your account will be blocked. You can either wait (6 hours) before trying to login again, or unlock your account by clicking on "Forgot your password?" and entering your email. You will receive an email with a link to generate a new password. Please be sure to check, at that time, exactly how your username is entered.
Please note that your username may be different than your email address (you can specify this while editing your account). This is a common mistake and the message "Incorrect username or password" is almost always interpreted as "Incorrect password". However, sometimes the problem is that the username you're trying to use does not exist. If you reset your password, please pay attention to the username you see in the form and use that one in combination with the password you are resetting.
