General best practice for the security of your Metamask wallet
You should be aware of how to keep your MetaMask wallet secure before considering locking it. As a result, we've included a list of the best practices for keeping your Metamask wallet secure.
- Never use the wallet on a shared computer.
- Use a desktop wallet rather than a mobile wallet. A phone is considerably simpler to steal or compromise than a laptop.
- Protect your seed phrase.
- Use a password manager such as Lastpass or KeePass to save passwords and seed phrases.
- Also back up on paper or in your favorite book that you would never part with.
- A good method for backing up is to store your secret phrase and password in 3 parts in different places
- You can also “salt the password and secret phrase backup” EG
- If your password is password1Secure then back it up as password15SecureSecret5 and write somewhere else your salt words: EG Secret 5
- Similarly if your secret phrase is happy phone hammer radio then back it up as happy grass phone hammer blue radio and write somewhere else your salt words: Eg. grass blue
- Generate a secure hashed password using password manager
- Check your browser extensions. If you are not using a browser extension then turn it off. Browser extensions can record your screen or log your keyboard easily.
- Run anti-malware and ant-virus programs regularly to check for key-logging software or spyware
- Regularly clear your browser's history and cookies
- Lock your Metamask account when not in use.
- Deactivate/turn off the Metamask extension when not in use
- If you hold a large amount of funds then consider creating several accounts in your wallet and splitting the stake between accounts Also consider moving profits out of your wallet at regular intervals
- NEVER EVER tell anyone your secret phrase or post it to any channel. If someone gets your secret phrase they can steal all your funds.
- Your password can only be used on your device so treat your device like a vault to protect it from theft and damage.
How To Lock Metamask Wallet
MetaMask isn't like a traditional website, where you're logging in to a remote server. Rather, MetaMask stores your Secret Recovery Phrase, private keys, and a certain amount of information about how you use MetaMask (the 'state logs') on your local device so that whenever you want to carry out an operation on a blockchain, your SRP and private keys are ready to be used.
In this sense, you don't log out of MetaMask, but you can lock the application so that you'll have to re-enter your password or biometrics to log back in.
