MetaMask's approach to security is through anonymity and entrusting private keys to users. Since the wallet does not keep users' personal information, accounts are protected by a user-generated password during installation and setup, or biometric data on mobile devices. The wallet can be recovered via a 12-word mnemonic phrase as the wallet doesn't keep custody of private keys. It is, therefore, necessary to keep this seed phrase safe as it will be essential if the device gets damaged or stolen.2

MetaMask has just one way of recovering a single wallet across multiple devices. This makes the wallet susceptible to hacks and malware. Notable among these are Banker Trojan, social engineering attacks, and other crypto scams. MetaMask wallet users can be attacked with phishing scams that prompt them to reveal their seed phrases on suspicious websites, or by downloading and installing a fake version of the wallet extension which hackers can leverage to steal users' assets after gaining control of the wallet.
