As you create your application, you need to determine whether to include authentication. You can:
Choose to not require authentication. Oracle Application Express does not check any user credentials. All pages of your application are accessible to all users.
Select a built-in authentication scheme. Create an authentication method based on available preconfigured authentication schemes. Depending on which scheme you choose, you may also have to configure the corresponding components of Oracle 10giAS, Oracle Internet Directory, or other external services. See "Using Preconfigured Authentication Schemes" and "Changing the Authentication Scheme Associated with an Application".
Create custom authentication scheme. Create a custom authentication method to have complete control over the authentication interface. To implement this approach, you must provide a PL/SQL function the Application Express engine executes before processing each page request. This function's Boolean return value determines whether the Application Express engine processes the page normally or displays a failure page. See "Creating an Authorization Scheme".
