MetaMask Security Best Practices Guide
Essential security practices to keep your MetaMask wallet and crypto assets safe.

Your First Line of Defense in Web3
MetaMask is your passport to the world of decentralized applications, but with great power comes great responsibility. Protecting your assets is paramount. This MetaMask security guide covers the essential best practices you must follow. Proper wallet protection is not just a recommendation; it's a necessity to keep your funds safe from an ever-growing number of threats.
Top 5 Security Best Practices
- Secure Your Secret Recovery Phrase: This is the master key to your wallet. Write it down on paper and store it in multiple, secure, offline locations. Never store it digitally (e.g., in a text file, email, or cloud storage) and never share it with anyone.
- Beware of Phishing Scams: Scammers will create fake websites or send DMs pretending to be from MetaMask support, asking for your seed phrase. MetaMask support will never ask for your phrase. Always double-check website URLs before connecting your wallet. This is a critical part of any crypto security routine.
- Use a Hardware Wallet: For the highest level of security, connect your MetaMask to a hardware wallet like a Ledger or Trezor. This keeps your private keys completely offline, meaning transactions must be physically approved on your device.
- Revoke Token Approvals: When you interact with dApps, you often grant them permission to spend your tokens. Regularly review and revoke unnecessary permissions using a tool like Etherscan's Token Approval Checker. This is a key step for ongoing wallet protection.
- Be Skeptical of Airdrops and Unknown Tokens: If you see a random token in your wallet, do not interact with it. It could be a scam designed to drain your wallet once you approve a transaction.
An Ongoing Process
Good crypto security is not a one-time setup; it's a continuous process of vigilance. By following this MetaMask security guide, you significantly reduce your risk of losing funds. Remember, in the world of self-custody, you are your own bank, so prioritize robust wallet protection at all times.
