Shouldn't the command to lock the account just be: 'alter user my account lock' 
?

Here is the trigger so far:

create or replace trigger my_logoff_trigger before logoff on my.schema declare
  sql_cmd varchar2(200);
  pwd varchar2(30);
begin
  dbms_output.enable(10000);
    update my_audit
    set logoff_time=systimestamp
    where os_pid=(SELECT P.SPID FROM V$PROCESS P INNER JOIN V$SESSION S ON
               S.PADDR = P.ADDR WHERE S.AUDSID = sys_context('USERENV', 
'SESSIONID'))
    and oracle_session_id=SYS_CONTEXT('USERENV','SESSIONID');
    commit;
    pwd:=generate_password();
    sql_cmd:='alter user my identified by '||pwd||' account lock';
    execute immediate sql_cmd;
  end if;
exception
  when others then
  RAISE;
end;
