Be cautious with services generating your addresses, you should look into bitcore.io it's easy to use

Here is how you can install it and run it
https://github.com/bitpay/bitcore#bitcore

Please, don't. Bitcore wallet / Copay is unmaintained, at least on the Bitcoin side (they focused mostly on Bcash).

Electrum has easy multisig and it is also cross-platform.
