Default password for new users at the developers server chat

When the portable version of the Client was launched for the first time, the option to connect to the developer's chat server (Network Software Solutions 2024 mychat24.com) was selected. The new user was registered automatically, without creating a password, specifying an e-mail address and a secret question.
The password was also not changed in the user profile menu in the future.
After updating the version of the Client, the Client asks for a Nickname (or UIN) and a password. Information about Nick (username) and UIN has been notised. But, unfortunately, no one asked for the password.
Perhaps there is a default password when creating a new user in this way? Or is there a way to recover the password, taking into account the above information?
Thanks in advance for your support.
