How to Install the MetaMask Wallet Extension

Installing the MetaMask Wallet Extension is quick and beginner-friendly. Follow these steps:

Click Add to Browser and confirm the installation.
Once installed, the MetaMask fox icon will appear beside your browser’s address bar.

How to Create a New MetaMask Wallet

If you’re setting up MetaMask for the first time, you’ll need to create a new wallet:

1. Click “Create a Wallet”

Choose the option to create a new wallet instead of importing one.

2. Create a Strong Password

This password protects your wallet on your device.
Make it:

  • At least 8–12 characters long

  • Hard to guess

  • Not used anywhere else

3. Secure Your Secret Recovery Phrase

MetaMask will show you a 12-word Secret Recovery Phrase.
This phrase is the master key to your wallet.

Important rules:

  • Write it on paper and store it securely.

  • Do NOT share it with anyone.

  • Do NOT store it in email, notes, or text messages.

  • Anyone with this phrase can access your wallet.

4. Confirm the Phrase

MetaMask will ask you to confirm the 12 words in correct order.

Once confirmed, your MetaMask Wallet Extension is ready to use.

How to Log In to the MetaMask Wallet Extension

Logging in is easy and takes just a few seconds:

1. Click the MetaMask Icon

Find the fox logo in your browser toolbar and click it.

2. Enter Your Password

Type the password you set during wallet creation.

3. Click “Unlock”

Your wallet dashboard will open, letting you:

  • View your tokens

  • Check your balance

  • Switch networks

  • Send and receive crypto

  • Connect to dApps

Your wallet stays unlocked until you close the browser or lock it manually.

Understanding the MetaMask Dashboard

Once logged in, you’ll see the main dashboard with several important sections:

  • Account name and address: Used for receiving crypto.

  • Balance: Shows ETH and other tokens.

  • Activity tab: Displays your transaction history.

  • Assets tab: Lists your tokens.

  • Network dropdown: Lets you switch between networks (Ethereum, BSC, Polygon, etc.).

This clean layout makes it easy for beginners to navigate their crypto wallet.

How to Add Networks to MetaMask Extension

MetaMask supports more than Ethereum. You can add other blockchains like:
