T-Mobile to Offer 802.1X. T-Mobile will use 802.1X authentication to secure local Wi-Fi links: Nancy will have more on this story later today — she filed a brief with the Seattle Times this morning about it — but I wanted to push out a more general note. Security at hot spots has been one of the bugaboos of the industry. 802.1X authentication with secured EAP (in this case, Protected EAP or PEAP) allows the secure login of a user and then secure exchange of unique WEP or WPA encryption keys.
