Open DayZ servers

No password means the public list did not mark the server as password-locked. Whitelist and private-hive servers can still refuse you after the connect. Read the server page before you cross a map for it. Owners who do want a password should set it in the DayZ config and keep RCon somewhere they can kick without logging into the box. That somewhere is CFTools Cloud. The box itself can be CFTools Architect.
