To Know who had accessed your account,
Login to your CrownPanel, click on the username dropdown and select Authentication log
Here you can view a list of all the login attempts made to your account along with the IP, Login time and its Status.
If you wish to disable the authentication log for your account, this can be done, please contact us via the client area via a Support Ticket and we will disable this for your account. Please note, once the authentication log is disabled we will not be able to find out who has logged into your account.
