user19133: Do all 3 private keys in a 2-of-3 multisig wallet have to exist on the same device at some point in order to generate the bitcoin address?
It would be ideal if the 3 private keys never existed on the same device together but it seems the examples I've found assume all 3 exist simultaneously when generating the bitcoin address and redeem script.

user12983: You do not need private keys at all to generate multisig m-of-n address!
You do need public keys. Yes, three for m-of-3 and eleven for 5-of-11 (for example)
