Can I find my WiFi password using Instabridge?

Only if you or someone else have added it. If you have added your WiFi password as a private WiFi on Instabridge you will be able to access it only via your version of the app or via your Instabridge account if you chose to log in. If you have added your WiFi password as a public WiFi on Instabridge you should be able to access your WiFi through any Instabrige app.
