Torus is one of Torus Labs' software wallets for storing Ethereum-based tokens, using an identification mechanism (OAuth2.0) provided by external authentication providers such as Google and Facebook. As a result, private keys can be managed through login information on Google, social networking services, etc., just like accounts in conventional web services, allowing for easy wallet creation, access, and management.
