Can't seem to reset password (or default pw is not admin?)

Have an older Mybooklive that I was trying to get access to (haven’t in a few months) and it was asking me for a password after I changed the IP address on it.

It doesn’t ask for a user name, just the password. I tried pressing the reset button on the back for several seconds, then typing “admin” as the password, but it keeps saying incorrect password.

Is the default password something else?

Nevermind, turns out the default password is null (no password), not admin.
