What are the default user name and password?

[wonderfuldh]

I have downloaded below
mikopbx-2022.2.102-x86_64.iso

I have successfully set up the VM in Virtual Box and can see the web UI of MikoPBX. However, when I tried to login using admin / admin The system just say 'Authorization error'.

What is the reason? Is the default user name and password really 'admin / admin'?

the default password should work. try to reset the password through the PBX console
