Coinbase takes down webpage that asked for user seed phrases

Coinbase has taken a webpage offline that asked users to directly input their seed phrases, or mnemonic codes, during a service integration process, following a public outcry. Cos (余弦), founder of blockchain security firm SlowMist, noted that for wallets, the security level of a webpage is significantly lower than that of a plugin or application. He added that requiring users to input their seed phrases is extremely risky, as this method can be easily imitated by phishing sites.
