## 3.4.7.4.1 About Configuring Authentication Schemes

Learn about configuring an authentication schemes for an Oracle APEX instance.

An Instance administrator configures the authentication scheme for a given Oracle APEX instance as follows:

1. Navigate to Manage Instance, Security:
   1. Sign in to APEX Administration Services.
   2. Click Manage Instance.
   3. Under Instance Settings, click Security.
2. Find Authentication Control.
3. Development Environment Authentication Schemes displays all available authentication schemes for the instance.

   The Status column lists each as either Not Current or Current. The authentication scheme designated as Current determines how Oracle APEX identifies and verifies instance administrators, workspace administrators, and developers. Depending upon the selected authentication scheme type, you can configure various settings to fine-tune authentication behavior.

4. To configure a new an authentication scheme for an instance, edit the settings and click Make Current Scheme.

Tip:

For all authentication schemes (even for external authentication schemes such as HTTP Header Variable) make sure that all users exist as developers or administrators in your workspace. Otherwise, APEX will not be able to verify in which workspace a user is allowed to work.

Tip:

You can also change the authentication scheme using the `APEX_BUILDER_AUTHENTICATION` parameter in `APEX_INSTANCE_ADMIN` package. See `APEX_INSTANCE_ADMIN`, Available Parameter Values in Oracle APEX API Reference.
