Understanding the Invalid Login Credentials Error in Oracle APEX

If you're an Oracle APEX user, encountering an "Invalid Login Credentials" error after a password reset can be frustrating. This issue is particularly prevalent when administrators reset passwords via the APEX Administration Interface. Many users have faced this issue when they are certain that their username and password are correct, leaving them puzzled and unable to access their workspace.

The Problem Explanation

Recently, a user shared their struggle after resetting one of their administrator passwords. Despite following the protocols for password complexity and triple-checking all login details, they were still met with the dreaded error. This experience resonated with many who venture into the realm of Oracle APEX, especially those utilizing the Autonomous Database Shared (ADB-S) environment.

What Causes This Error?

When an APEX workspace is created, each administrative account is linked to a specific database schema. While at first glance this may appear similar to other installations, a crucial distinction must be made—APEX in ADB-S utilizes "Database Credentials" during login. This means that if there is a mismatch between the password set in the APEX UI and the password for the associated database schema, access will be denied, triggering the "Invalid Login Credentials" error.

Guided Steps to Resolve the Issue

To regain access to your Oracle APEX workspace after being locked out due to this error, follow these organized steps carefully:

Step 1: Reset the Password in APEX UI

Log in to the APEX Administration Interface.

Navigate to the users section where the administrator accounts are listed.

Select the administrator user for whom you want to reset the password.

Enter a new password that meets the complexity requirements outlined by ADB-S.

Confirm the new password and save the changes.

Step 2: Update the Associated Schema Password

Next, you’ll need to ensure that the password for the administrator's schema in the database matches the new password you just set in APEX:

Access your database management tool (e.g., SQL Developer, etc.).

Connect to the database as a user with the necessary permissions to alter passwords.

Run the following command to update the schema password to the same one you set in APEX:

Replace <username> with the schema user associated with your administrator account, and <new_password> with the password you entered in the APEX UI.

Step 3: Attempt to Log In Again

With both passwords synchronized:

Return to the APEX login page and input your credentials.

Attempt logging in with the updated username and password combination.

What to Do if the Error Persists

If you continue to experience issues despite following these instructions:

Double-check the username and the exact spelling of the password (pay attention to capitalization).

Ensure that no spaces are inadvertently added at the end of your username or password.

If necessary, repeat the password reset process to ensure there are no errors and changes have been applied correctly.

Conclusion: Safely Navigating Oracle APEX Login Issues

Getting locked out of your Oracle APEX work environment can be daunting, but understanding the linkage between your APEX credentials and database schema passwords is key to troubleshooting login issues. By resetting both the APEX and schema passwords in tandem, you can restore access efficiently and prevent future frustrations.

Remember, the catch that APEX Login UI in ADB-S uses database credentials is crucial for a smooth experience. Keep
