Penn State’s Jabber service allows people with a valid Penn State Access Account to activate their own Jabber account. Their Jabber screen name is their Access Account user ID@chat.psu.edu. (e.g., "firstname.lastname@example.org"), and their password is their Penn State Access Account password. Penn State Jabber accounts do not support a second or separate password. To change their Jabber account password, users must change their Penn State Access Account password. This can be done at work.psu.edu
Jabber configurations for Penn State supported chat clients can be found here.
