As a DBA, I've gotten many requests for changing the password.
There are steps that you can use to change your password via Oracle SQL Developer by yourself without need to seek help from DBA.
You can also use this way to change the password which is already expired !
Step 1: Open Oracle SQL Developer
Step 2: Right click on your connection.
If you have not created your connect yet, you need to create one.
Step 3: Choose "Reset Password"
You need to provide the current password, and the new password.
=> Depend on password policy, It may require complex password/ or you can not reuse the old one.
