Reset the Password for Custom Schemas
Oracle Fusion Data Intelligence provides default schemas (also known as users) such as the ADMIN schema
        and OAX_USER schema. You can create custom schemas to meet your
        customization requirements. 
               
The custom schemas enables you to run your own SQL queries against the
                database or sign in and view the data in the tables of the associated Oracle Autonomous Data Warehouse instance. The security policy of Oracle Autonomous Data Warehouse requires you to change the passwords for the custom schemas every 365 days.
                     
                        
                  
                  
                  Note:
You need to be either an Oracle Cloud Infrastructure administrator or an administrator user with the necessary privileges to sign in and reset the password for the custom schemas.You can change the password for the custom schemas using either SQL
                Developer or the Oracle Cloud
                                Infrastructure Console. To change the password using SQL Developer, sign in to SQL Developer
                using the credentials of the ADMIN schema and run the command
                that's suggested to use while changing the password from the Oracle Cloud
                                Infrastructure Console.
