Why do you want to write a trigger/code when this facility is provided by Oracle itself ? No one can log into Oracle unless one holds a valid username/password to log on.

Or may be the OP is looking into a custom authentication like storing the application users/passwords in the database.
A detailed information would be more useful.

Password can be encrypted and stored in the table. Example of encrypting the password can be found here.

http://www.orafaq.com/scripts/plsql/password.txt

Connect to the database with a default userid/pwd and then try to crosscheck the entered userid/pwd with the one stored in the table. Make sure that the default userid/pwd has select only privileges on the user table.
