Passing Security Information into Browser Applet

[Allexicus Kernikus]

I have a security issue to which I have yet to find a viable solution.

A JSF application asks the user for her credentials. These are stored in a cookie.

For some functionality a browser applet is used.

How should I access/pass the user credentials to the applet?

To be specific: the applet needs access to the username, not the password.

Many thanks in advance!
