fingerprint readers itself.

When a username argument is used for a method, a PolicyKit check is done on the
|
||||
<doc:tt>net.reactivated.fprint.device.setusername</doc:tt> PolicyKit
|
||||
action to see whether the user the client is running as is allowed to access data from other users.

<doc:para>
|
||||
By default, only root is allowed to access fingerprint data for users other than itself. For a normal user,
|
||||
it is recommended that you use an empty string for the username, which will mean "the client the user is
|
||||
running as".
