Help with Wifi setting

[android2200]

I have a Wifi network at work and it requires a NEW password generated from a secure token each time when I try to re-connect. Since Android Wifi setting remembers the password, if it try to re-connect using the saved password (it becomes invalid after disconnected), my secure token become invalid. If i remember to remove the connection each time after i disconnect, I can enter new password when the connection is discovered as a new connection again. The problem is what if I forget. In addition it is inconvenient. Do you know any Android application supports remove a chosen WiFi connection password each time the connection is lost? Thanks for your help!
