Targets Web

Hi,

can a web app read the MAC address of the PC (or Macintosh) of the CLIENT?
Or read a data inside a folder on client PC?

(My problem is to automatically authenticate
some client to access to the selected web page of the web app deployed with Xojo.)

Thank you for help…

no. no.

you can only ask for login/password and store a token in the Cookie for relogin later.

Thank you

No
And the MAC address can actually be spoofed anyways
