There are many portals in my area belonging to my faction, and I want to link them.
According to this page I must hold the portal key for the destination portal in my inventory.
How can I get the portal key for a portal belonging to my own faction?
Or, more generally, how can I link friendly portals that I don't have portal keys for?
Best Answer
You have to go there and hack the (destination) portal to obtain the key (yes, you need to hack "friendly" portals anyway to get supplies), or trade keys with team members by dropping/acquiring them.
Also, resonators "drop" keys which are used for links when one end is blown up that you can pick up.
