Database acces and Password

I used TOAD for all my SQL queries, however I have noticed that when I change my password for access to my databases and they I try to used a SQL query created with my old password it will suspend my new password. Now there is a check box to save password, that is unchecked. Is there a way to not have my password associated with the SQL queries. This is a real pain to get my password reset all the time.

Is there a setting that needs to be checked or unchecked so that the password is not linked to the queries???

Please help anyone??
