I am trying to get the WiFi passwords programmatically from a non-rooted Android device.
All I need is to be able to read the passwords, I do not need to be able to edit them.
Can I get permission in the manifest file?

If your application is a privileged app (that is - installed in /system/priv-app for example using SuperUser) then you can use the new WifiManager#getPrivilegedConfiguredNetworks() API in Lollipop and newer.

I wonder if this is how the Google Home app does it when onboarding chromecast/home devices. It really does make the onboarding slicker.
This is not possible as this would be a major security risk.
You may be able to if the phone is rooted but I do not know, I would imagine, and hope, even if you could get to where it is stored on the phone, it would be encrypted.

No, again this would be a security risk, and why would you need to, if you are connected, you probably know the password

Google Chromecast (now Home) can read current wifi password and provide it to Chromecast...

Well, Home has the necessary privileges to do so, it's unfair, but it's Google ;)
Most of the time, the Wi-Fi credentials are managed by the wpa_supplicant daemon which store this in a configuration file like /data/misc/wifi/wpa_supplicant.conf.
In this file you will find network structures which store the remembered networks like this:
network={
ssid="example"
key_mgmt=WPA-PSK
psk="passphrase"
}
This file is usually own by a system user like wifi or root. So you have to be root if you want to read it directly.
Nevertheless, you can get the ssid or other network variables of the remember networks by using the wpa_cli command:
$ wpa_cli get_network <id> ssid
"example"
But if you try with the psk you will get a * as this is a security risk:
$ wpa_cli get_network <id> psk
*

This file doesn't have such information in latest android (kitkat). How to do it in kitkat?
There is no API support for reading/writing WiFi passwords for APKs not signed with the system key. So you won't be able to retrieve it.
