To recover your password, click the "Forgot your password?" link on the login page, after which the password recovery page will open. In the "Email" field, enter your email address and pass the robot check. After clicking the "Get the link" button, a link will be sent to your email.
When following the link, the system will generate a new password and offer to change the password to your own. It is important to remember the system password, since it will be required for subsequent password changes.
