I have no idea how your functions/codes look like, the code below is just a typical example. Change it according to your own settings.

pawn Код:

if(!strcmp(cmd, "/changepass", true, 11))
    {
        new tmp[32];
        tmp = strtok(cmd, idx);
        
        if(strlen(tmp) < 5 || strlen(tmp) > 20)
        return SendClientMessage(playerid, -1, "Your new password needs to be within 5 - 20 characters.");
        
        format
        (
            PlayerInfo[playerid][pKey],
            sizeof PlayerInfo[playerid][pKey],
            "%s", MD5_hash(tmp) //<-- Just replace MD5_hash with the function you use.
        );

        new message[128];

        format
        (
            message,
            sizeof message,
            "Your new password has been set to: \"%s\" Use it yo login next time!",
            tmp
        );

        SendClientMessage(playerid, -1, message);
        
        return 1;
    }
