Installing the MetaMask Chrome Extension

Installing MetaMask is a simple process when downloaded from official sources.

Step 1: Visit the Official Website

Navigate to the official MetaMask website and select the Chrome browser extension. Alternatively, use the official Chrome Web Store listing.

Step 3: Create or Import a Wallet

After opening the extension, users typically choose between:

• Creating a new wallet

Creating a New Wallet

When creating a new wallet, MetaMask generates a recovery phrase that serves as the backup for your wallet.

During setup:

• Create a strong password.
• Carefully record the recovery phrase.
• Verify the recovery phrase.

The recovery phrase is the only way to restore your wallet if your device is lost or replaced.

Understanding the Recovery Phrase

The recovery phrase is one of the most important security elements of your wallet.

It should always be:

• Written on paper
• Stored offline
• Kept private
• Protected from damage

Never:

• Share it with anyone.
• Save it in cloud storage.
• Email it to yourself.
• Enter it into unknown websites.

Anyone who obtains your recovery phrase may gain access to your wallet.
