You can do 2-of-4 multisig in any Bitcoin fork.
I've never seen an easy < 3 min multi sig solution for phone + comp for dummies.
Maybe I'm missing something?
Yeah you are a bit blind.
Copay.io, Mobile and webwallet with multisig using p2sh of course, works on all devices including Linux, Windows, Osx, Windows Mobile, Android and iOS. (Btw. Bitpay also works on instantx for bitcoin - impulse.is - using smart contracts you may know from ethereummmm... funnily enough most people dont even know that most of the ether stuff can be easily implemented in btc).
Bitgo - also, same as above, not sure where it runs, tested only browser.
Greenaddress.it, Same as above but also with Instantx , a lot of exchanges support their instantx stuff already btw.
Bitalo has also a multisig wallet
Coinbase also afaik but as they are US only i never used them...
And prolly a ton more, those are just the ones i tried on my phone.
Oh i nearly forgot, i think mycelium also has multisig support nowadays....
I just tested, registering on copay and joining a multisig wallet took me 43 seconds on my pc and mobile phone, i use the phone as my 2FA auth so to say.
Nuff multisig?
