To create custom authentication in Oracle APEX, you can use the built-in authentication schemes or create your own custom authentication scheme.
To create a custom authentication scheme, you will need to write PL/SQL code to authenticate users against a custom table or source. This can involve validating user credentials, checking against a database table, or integrating with an external authentication system.
You can then configure your custom authentication scheme in APEX by going to Shared Components > Authentication Schemes and creating a new scheme. Here, you can specify the PL/SQL code to use for authentication, as well as any additional settings or parameters required.
Once your custom authentication scheme is configured, you can apply it to specific pages or applications within APEX to enforce authentication for those areas. This allows you to create a tailored authentication process for your APEX applications that meet your specific security requirements.

What is the best practice for implementing custom authentication in Oracle APEX?
The best practice for implementing custom authentication in Oracle APEX is as follows:
- Use a custom authentication scheme: Create a custom authentication scheme in Oracle APEX that allows you to define your own authentication logic. This can include validating user credentials against a database table, LDAP directory, or external authentication service.
- Secure your authentication logic: Ensure that your custom authentication logic is secure, by hashing passwords, using prepared statements to prevent SQL injection, and implementing proper error handling to prevent information leakage.
- Implement multi-factor authentication: To enhance security, consider implementing multi-factor authentication for your custom authentication scheme. This can include using SMS codes, email verification, or biometric authentication.
- Use SSL/TLS: Secure communication between the client and server by using SSL/TLS encryption to prevent eavesdropping and man-in-the-middle attacks.
- Regularly review and update your authentication mechanism: Regularly review and update your custom authentication mechanism to address any security vulnerabilities that may arise. This includes staying up to date with security patches for Oracle APEX and any third-party authentication services you may be using.
- Monitor and audit authentication activity: Implement logging and monitoring mechanisms to track authentication activity, including successful and failed login attempts. This can help you identify and respond to potential security incidents in a timely manner.
What is the process for creating custom error messages in Oracle APEX authentication?
To create custom error messages in Oracle APEX authentication, you can follow these steps:
- Log in to your Oracle APEX application.
- Navigate to the Shared Components section of your application.
- Click on Authentication Schemes.
- Find the authentication scheme you are using for your application and click on Edit.
- In the Authentication Scheme Attributes page, find the Error Messages section.
- Click on the Add Error Message button.
- In the Add Error Message dialog box, enter the error message you want to display in the Error Message field.
- You can also choose the type of error message (Error, Warning, or Notification) from the Type drop-down menu.
- Click Apply Changes to save the custom error message.
- You can add multiple custom error messages by repeating steps 6-9.
- Once you have added all the custom error messages you need, click Apply Changes to save the changes to the authentication scheme.
Your custom error messages will now be displayed when the user encounters authentication errors in your Oracle APEX application.
What are the benefits of using custom authentication in Oracle APEX?
- Enhanced security: Custom authentication methods allow for a higher level of security as developers have more control over how user credentials are validated and stored.
- Flexibility: Custom authentication allows developers to tailor the authentication process to specific requirements or regulatory compliance needs within their organization.
- Integration with existing systems: Custom authentication methods can be integrated with existing user databases, LDAP directories, or other authentication services to streamline user management and reduce duplication of efforts.
- Improved user experience: With custom authentication, developers can create a seamless and user-friendly login process that aligns with the overall design and functionality of the APEX application.
- Scalability: Custom authentication methods can easily scale to accommodate growing user bases or changing authentication requirements without compromising security or performance.
