- Scenario

Restart Adobe Acrobat to Clear Cached Security Credentials
Adobe Acrobat temporarily remembers passwords during an active session. Completely closing and reopening the app forces it to ask for the password again.
When you open or apply a password to a PDF, Acrobat temporarily caches the security credentials for the duration of that session. This is designed to prevent repetitive password prompts while you are actively working. To verify that the password protection is working properly and to trigger the existing password prompt, you must clear this cache by fully restarting the application.
Save any changes you have made to the PDF document.
Completely close Adobe Acrobat by clicking the 'X' in the top right corner or selecting 'Exit' from the File menu.
Launch Adobe Acrobat again and open the protected PDF document.
Navigate back to the document's Security properties to change the password. Acrobat will now prompt you for the existing password as expected.
