Recently there has been terrible news about jaxx wallet being hacked, and users losing all their coins. I know coinomi wallet is open sourced, so are we sure it is safe? I would feel better if someone really knew and could answer this.
edit Upon trying to look into it, they claim to encrypt the entire wallet with the user's password. I sure hope so...
update So I contacted coinomi support and here is what they said "Regarding Coinomi security, the wallet encrypts the private keys and recovery phrase using AES in CBC mode with the encryption key being the Scrypt hash of the user's password. So if you have a (good) password set and lose your phone it is practically impossible to decrypt your private keys. Jaxx as far as we know, does not encrypt your private keys even if you set a PIN."
Sounds pretty safe if you pick a strong password, check your password's strength here: howsecureismypassword.net
