Where do I find my Network Security Key?

[giddyup]

Just bought a new computer and it's asking me for my Network Security Key. Where do I find it?

WiFi password, often printed on the bottom of the WiFi router, if it hasnt been changed from defalt.

Or a windows homegroup password, from another PC in the homegroup.

Thanks, but it turns out it's the password it wants, not the security key, even though that's what it asked for.
