I would imagine folks are scanning sensitive documents/PII and such. Can the developers enable FaceID or allow the user to create a custom passcode?
I hope you are doing well. As per the above description, I understand that you want to add a security layer to access Adobe Scan.
This feature would be an excellent enhancement to the application. Would you mind filling out the feature request form so that it reaches out to our Engineering Team for them to look into it and try to implement it in the upcoming updates.
