How to remove cached user credentials in SecureW2
From Provider Wiki
Previous versions of SecureW2 used Microsoft's cache for storing PennKey credentials in SecureW2. Unfortunately, the only method to remove credentials involved either editing the registry manually, or reinstalling SecureW2. With the latest installer from XpressConnect, credentials are cached within SecureW2 and can be removed when the user desires.
Removing Cached Credentials
Important: Begin by installing the latest version of XpressConnect from AirPennNet-Help. Only versions of SecureW2 installed via XpressConnect from AirPennNet-Help on March 15, 2011 (or later) have the configuration option which allows users to remove cached credentials through the settings screen. (Older Secure W2 versions, installed before XpressConnect 3.5.66 use Microsoft caching, and therefore do not offer this option.)
1. Navigate to the Windows wireless profile and select the "Advanced" tab for the AirPennNet wireless profile.
2. Click "Settings" next to: SecureW2: SecureW2 EAP-TTLS. 3. On the "User Account" tab in SecureW2, check the "Prompt user for credentials" box.
4. Cycle the network connection either by turning off and then turning back on the wireless card, or restarting the system.
5. A balloon should appear in the system tray when the computer reconnects. The user should click it and enter the new username and password.
Note: It is strongly recommended that users do not uncheck the "Save User Password" box as this can result in the user being prompted for credentials very frequently when in areas where their client may roam between access points.
