The sample of procedure to change Paradox password in a protected table:

procedure TForm1.SpeedButton1Click(Sender: TObject);
begin
    Session.AddPassword('OLDPASSWORD');
    Table1.Close;
    Table1.Exclusive:=true;
    Table1.Open;
    AddMasterPassword(Table1,'NEWPASSWORD');
end;

Be sure you have "BDE" unit in uses clause.
Code bellow is from Delphi help:

procedure AddMasterPassword(Table: TTable; pswd: string);

const
  RESTRUCTURE_TRUE = WordBool(1);
var
  TblDesc: CRTblDesc;
  hDb: hDBIDb;
begin
  { Make sure that the table is opened and is exclusive }
  if not Table.Active or not Table.Exclusive then
    raise EDatabaseError.Create('Table must be opened in exclusive ' +
      'mode to add passwords');
  { Initialize the table descriptor }
  FillChar(TblDesc, SizeOf(CRTblDesc), #0);
  with TblDesc do begin

    { Place the table name in descriptor }
    StrPCopy(szTblName, Table.TableName);
    { Place the table type in descriptor }
    StrCopy(szTblType, szPARADOX);
    { Master Password, Password }
    StrPCopy(szPassword, pswd);
    { Set bProtected to True }
    bProtected := RESTRUCTURE_TRUE;
  end;
  { Get the database handle from the cursor handle }
  Check(DbiGetObjFromObj(hDBIObj(Table.Handle), objDATABASE, hDBIObj(hDb)));
  { Close the table }
  Table.Close;

  { Add the master password to the Paradox table }
  Check(DbiDoRestructure(hDb, 1, @TblDesc, nil, nil, nil, False));
  { Add the new password to the session }
  Session.AddPassword(pswd);
  { Re-Open the table }
  Table.Open;
end;

Cheers,
Igor.
