A few days ago i have changed my network password, then i entered that password to my iPhone, then i forgot my password only password is in my iPhone. Is there a way to get back my password from my iPhone?
Hope it wasn't the same password that's used to log onto your router. If it was you'll need to reset the router back to factory settings and start all over again. With some routers you may need to start all over again anyway as you need the old WiFi password to change to a new one. Good luck.
Only if that app was in place when you set that password. Like a password keeper. Nothing to recover am entered password after the fact.
Reset your password at the router or reset router.
Is this not your wifi?
