Mobilewallet and nanowallet are "brainwallets". That means password = private key. And i only need to save the password to be able to open the same account in any other device with mobile or nanowallet ?
Anybody ?
No. The wallet has a file that contains the key. That file is passworded and therefore one cannot open up the same wallet in another device without the file.
So, no, it is not a brain wallet per se.
I see... And android needs rooting to get that file. Fortunately the private key can be revealed in the wallet, so i just back that up along with the password so now it can be recreated on other device, great !
