Using MetaMask safely
MetaMask has considerable security features that make it a reasonably safe software wallet. First of all, it never stores your wallet information on its own servers. It stores it on the internet, but MetaMask never has access to it but it’s possible a skilled hacker could find the encrypted file on your side.
The greatest technical vulnerability of MetaMask wallets that we know of is also what makes it so convenient. Every cryptocurrency wallet has a public key, which is publicly available to anyone and used to send you cryptos, and a private key. The private key should be kept a secret from the outside world because it’s what gives you access to the funds in the wallet.
MetaMask stores your private key online in your browser’s data cache so you can access your wallet easily. It is encrypted and can only be decrypted with your password, but it’s much easier to brute-force guess most passwords than 64-character private keys.
MetaMask wallets are most often compromised through phishing and malware attacks and not direct cyberattacks. There are a few basic steps that can help keep your cryptos secure, but they can’t be perfect.
Here are the basic foundations of security:
- Use a secure password that is difficult to guess
- Never type your seed phrase into anything other than the real Metamask
- Never export your private key while screen sharing with anyone
- Do not connect with suspicious websites
If you are still worried about losing your cryptos to hacks, you might want to invest in a hardware wallet. Even MetaMask itself recommends investors with larger wallets store the bulk of their portfolio in a hardware wallet.
