To use MetaMask on a laptop, install the browser extension, create or import a wallet, and connect it to decentralized applications (dApps).
Creating a New Wallet

Securing Your Seed Phrase
The seed phrase is crucial for recovering your wallet and must be handled with utmost care:

Security Best Practices
Backup Seed Phrase
Properly backing up your seed phrase is critical for the security and recovery of your MetaMask wallet:
- Write It Down: When MetaMask generates your seed phrase, write it down on a piece of paper. Avoid storing it digitally to prevent hacking risks.
- Multiple Copies: Create multiple copies of the written seed phrase and store them in different secure locations such as a safe, a locked drawer, or a bank deposit box.
- Avoid Sharing: Do not share your seed phrase with anyone. Anyone with access to it can control your wallet and its assets.
- Periodic Checks: Regularly check that your seed phrase is still accessible and readable, ensuring it remains secure and usable in case of emergency.
Setting a Strong Password
Creating a strong password for your MetaMask wallet is essential to ensure the security of your digital assets:
- Use a Unique Password: Ensure that the password for your MetaMask wallet is unique and not used for any other accounts or services.
- Combine Characters: Create a password that includes a mix of uppercase and lowercase letters, numbers, and special characters. This combination makes the password harder to guess.
- Avoid Common Phrases: Do not use easily guessable passwords such as “password123” or common phrases. Aim for a combination that is difficult to predict.
- Length Matters: Aim for a password that is at least 12 characters long. Longer passwords are generally more secure and harder to crack.
- Avoid Personal Information: Do not include personal information such as your name, birthdate, or common words related to you.
- Use a Passphrase: Consider using a passphrase, which is a sequence of random words or a sentence that is easy to remember but difficult for others to guess.
- Password Manager: Use a reputable password manager to generate and store your password securely. This can help you create strong, unique passwords without having to remember them all.
