Unfortunately, you cannot access the WiFi passwords stored in the iPhone directly. It’s different on the Mac: if you want to find out the password for a WLAN, just look at the bunch of keys. This still doesn’t work on the iPhone. What is at least possible is to share the active WLAN connection directly with other Apple users, but you will not find out the actual password that way. It’s annoying if you don’t remember this yourself and would like to share it with Android and Windows users, for example.
iOS 16: Reading the WiFi password on the iPhone is finally possible
With iOS 16 this will change. There’s the possibility to read out the password of the active WLAN connection directly (Source: MacRumors). And this is how it works: Open the WLAN settings, tap on the actively connected network. At this point you will see a new option – Password. If you now tap on it, the WLAN password will be displayed directly. However, it is still necessary to authenticate yourself beforehand with Face ID, Touch ID or a passcode.
Pretty handy, because now you can share wifi password with people, who cannot explicitly rely on the automatic release, i.e. people who do not own an Apple device.
Personaly thinking: Finally this is also possible with the iPhone. How often have I had to use a Mac in such cases, provided the computer was previously connected to the WLAN in question. With iOS 16, all you have to do is grab your iPhone. Why not just like that, Apple?

When will Apple release iOS 16?
Currently only registered developers have access to iOS 16, according to Apple the public and free beta test should start in July. The iPhone update will then be released in autumn, most likely, as always, a few days before the new iPhones go on sale. Ergo: In mid-September it could already be time.
