Coinomi is a lightweight, secure, open-source, universal, multiple currency HD wallet. Your private keys never leave your device and you only need to back it up once. After backing up you can simply use a PIN for normal verification.
[Notice: While we are fans of using Coinomi’s Wallet to manage day to day holdings of multiple cryptocurrencies within one app we do not recommend holding large portions this way. That being said for easily converting between crpytos and storing daily amounts we couldn’t be happier.]
