Displaying user's password I need to know if there is a way in SQL*Plus to display the password of a certain username?

At my job, sometimes the developers ask me what happened to their account, and what their password is. When I try to display the username and password, the password shows as blank.

Could you please help?
What you are asking is impossible, unless you brute-force the password hash for the user.

How do you expect a system to be secure if passwords are stored in plain text?
