MetaMask Security Settings

1. Enabling Strong Passwords and Two-Factor Authentication:

   • Utilize Two-Factor Authentication (2FA) via a mobile app like Google Authenticator or a hardware security key for an extra layer of protection.

2. Safeguarding Seed Phrase and Private Key:

   • Store the MetaMask seed phrase securely both offline and encrypted; avoid digital storage.
   • Keep private keys secret and only enter them when absolutely necessary, like when accessing another wallet or signing sensitive transactions.

3. Managing Extensions and Permissions:

   • Only install trustworthy extensions from reputable sources.
   • Regularly review installed extensions and remove any suspicious or unused ones.
   • Disable any unnecessary permissions granted to extensions to minimize security risks.

4. Understanding Phishing Attempts and Smart Contract Scams:

   • Be vigilant about phishing scams where attackers attempt to trick users into revealing their login credentials or seed phrase.
   • Inspect URLs carefully and never access MetaMask from unfamiliar links.
   • Scrutinize smart contracts before interacting with them. Verify their legitimacy, functionality, and reliability before approving any transactions.

5. Utilizing MetaMask's Security Features:

   • Enable the Fogger feature to obscure sensitive information on-screen, preventing visual keylogging attacks.
   • Utilize Phone Verification as an additional security layer, requiring a phone number for certain transactions.
   • Adjust Advanced Gas Settings to control gas prices and prevent accidental high-value transactions.

6. Employing Best Practices for Transaction Verification and Confirmation:

   • Carefully review transaction details (e.g., recipient address, amount, gas fee) before confirming.
   • Verify transaction information through multiple methods, such as comparing the recipient address on multiple platforms.
   • Utilize transaction acceleration tools with caution to avoid potential risks associated with expedited transactions.

7. Maintaining Up-to-Date Software and Reporting Suspicious Activity:

   • Keep MetaMask and related software up to date with the latest security patches.
   • Report any suspicious activity, compromised accounts, or potential security vulnerabilities promptly to MetaMask or relevant authorities.
