You can secure remote access to Files Pro by setting up a username and password. Anyone who attempts to connect remotely to Files Pro will then be required to autheticate with a username and password before the connection is established.
Note: If you want to secure local access to Files Pro you should set up a Passcode Lock.
To enable remote authenticaiton tap the gear icon to display the settings, then tap Authentication under Remote Access.
Entering a username and password in the next view will enable remote authentation.
If at any time in the future you wish to disable remote authentation, just enter an empty password.
Turning Remote Guest Access on allows remote users to connect to the Public folder without requiring authentication. Guests have read and write access to this folder.
Guests can connect by appending Public to the Files Pro URL e.g.
http://192.168.0.2/Public
If you want to protect local access to your documents you can enable the Pro Features via an in-app purchase (found in this application's settings).
