Hello,
I'm trying to find a way, to programmatically get the password, of current WiFi connection, so I could use the password to connect another device to the same WiFi.
One of the possibilities that I've found was using a terminal command: "security find-generic-password -ga TypeInYourWiFiNameHere | grep “password:”".
Is there any other, more appropriate way to do this in Objective C/C++? Asking user for permission is completely fine and understandable.

On what platform?

I'm trying to do this for Mac.
The Mac stores the Wi-Fi password in the System keychain. The best way to get it is via CoreWLAN’s CWKeychainFindWiFiPassword function. For example:
import CoreWLAN
func password(for ssid: String) throws -> String {
let ssid = Data(ssid.utf8)
var passwordQ: NSString? = nil
let err = CWKeychainFindWiFiPassword(CWKeychainDomain.system, ssid, &passwordQ)
guard err == noErr else {
throw NSError(domain: NSOSStatusErrorDomain, code: Int(err), userInfo: nil)
}
return passwordQ! as String
}
This will prompt for an admin password. There’s no way to get this info without that prompt, for obvious security reasons.

Is there a way to do this on iOS?
Not directly.
Why are you trying to do this? Most folks who ask this question are trying to perform some sort of accessory integration task, for example, configure a Wi-Fi based accessory to join the user’s Wi-Fi network. The recommended approach for that is WAC. See TN3111 iOS Wi-Fi API overview for links to more info.
If WAC isn’t applicable to your issue, you’ll have to ask the user for their Wi-Fi password.
