WiFi Passwords is a new tweak available for some time in Cydia that allows iDevice owners to view all the passwords used to connect to Wi-Fi HotSpots. Normally, iOS remembers our passwords, but there is no menu in which they are actually displayed, so if you have forgotten one, you must be careful not to restore or reset the network settings. Tweak appears in the form of an application in Springboard in which we have listed the names of Wi-Fi networks and each password associated with that network.
This app displays all the WiFi passwords you have entered when connecting to secure networks. Very handy if you forgot a password and need to connect another device, or tell a friend the password for a coffee shop without asking that embarrassing question again. Tap hold on the password to copy it to the clipboard. Requires iOS 3.0 or later.
WiFi Passwords is available for free in Cydia in the BigBoss repo and you can install it following this link.
