How can I login on console server

I have successfully installed and activated nextcloud server v. RaspberryPi5_v1.55.3mon my rpi 5.

The web browser interfaces work without problems.
But I want to format and enable a nvme drive, so I want to log in on the console of the server.

I take it that the user name is ncp, but non of the passwords used in the browser (for ncp-admin of ncp user) is correct; I changed both passwords successfully in the browser, but those do not give access too.

Trying to login with user pi or root, with the default passwords, also fail.

Any idea how to get into the console?
Thanks for any answer!

Solved, by enabling SSH, which also gives a new user, set passwd, and enabling sudo for that user. Don´t know if that’s the normal way to go, but it works for me.
