SlowMist Cosine: The Humanity Protocol project stores the plaintext private key in sessionStorage

founder of SlowMist, Yu Xian, disclosed that the Humanity Protocol project directly stores plaintext private keys in the browser's sessionStorage, provided that the user logs in using a Web2 method, such as email. The platform automatically assigns a wallet to the user. Fortunately, this is only a test network and has not caused any actual harm yet.
