You can reset your password most of the times. If you try to log at on an online casino, you can find a link with 'forgot my password'.
Annoying: you want to log in to play an online game of roulette, but unfortunately: you can’t remember your password. What to do?
In most casinos you can indicate you lost your password. In a few casinos this is not an option, so you have to contact the customer service. Most casinos will send you an email with a new or temporary password, with which you can log in. After logging in you can change your password.
In some casinos you need to answer a few personal questions, in order to receive your password through email.
