### Config Breakdown<\/p>\n
– **`time-window`** \u2014 Defines how far back (in seconds) the plugin looks when counting logins. A value of `60` means any login within the last minute is counted.
\n– **`max-logins`** \u2014 The threshold. If a player’s login count *within the window* exceeds this value, their join and leave messages are suppressed for that event.<\/p>\n
