When I am in range of a portal and when I click and hold, it displays 4 options.
- Hack
- Hack No Key
- Fire XMP
- Deploy
So whats the main difference between "Hack"ing a portal and "Hack No Key"ing a portal?
Hack no key, as the name suggests, will give you no key. You can also achieve this via glyph hacking and signaling 'less' via the control channel, but this is a lot more convenient.
It is quite useful while farming for items, or travelling in a new area you know you need no keys from, but it's good for your explorer badge. Spares you getting rid of the keys later.
