MetaMask has become one of the most widely used cryptocurrency wallets in the world, especially for those engaging with decentralized applications (dApps), non-fungible tokens (NFTs), and decentralized exchanges (DEXs). Its popularity stems from its user-friendly interface, cross-platform availability, and seamless integration with major web browsers like Chrome, Firefox, Brave, and Microsoft Edge.
Whether you're new to the world of Web3 or expanding your digital asset management tools, installing MetaMask is a straightforward process that opens the door to the decentralized internet. This guide walks you through every step—from installation to initial setup—with clear instructions and essential security tips.
Installing the MetaMask Browser Extension
To get started, visit the official MetaMask download page. While the wallet is available as a mobile app for iOS and Android, this guide focuses on setting it up as a browser extension. Supported browsers include Google Chrome, Mozilla Firefox, Brave, and Microsoft Edge.
For demonstration purposes, we’ll use Google Chrome. However, the installation steps are nearly identical across all compatible browsers.
- Navigate to the MetaMask download site.
- Click on “Install MetaMask for Chrome” (or your preferred browser).
- A new tab will open, redirecting you to the Chrome Web Store.
- In the top-right corner, click “Add to Chrome.”
- Confirm the action in the pop-up window by selecting “Add extension.”
Once installed, the iconic fox logo will appear in your browser’s toolbar—indicating that MetaMask is ready for setup.

Creating or Importing Your Wallet
After installation, click the MetaMask icon to launch the setup wizard.
You’ll be presented with two options:
- Create a Wallet
- Import Wallet
Choose “Create a Wallet” if you're setting up MetaMask for the first time. Select “Import Wallet” only if you already have an existing account and want to restore it using a recovery phrase.
Next, you’ll be asked to agree to MetaMask’s Terms of Use. Read through them carefully, then proceed by clicking “I Agree.”
Now, create a strong password. This password protects your wallet within the browser and must be entered each time you access MetaMask. Make sure it's unique and not used elsewhere.
Security Tip: Never store your password in a plain text file or note-taking app. Use a trusted password manager instead.
Backing Up Your Secret Recovery Phrase
This step is the most critical part of the entire setup process.
After setting your password, MetaMask will generate a 12-word secret recovery phrase (also known as a seed phrase). This phrase is the master key to your wallet. With it, anyone can fully control your funds.
Warning: Never share your recovery phrase with anyone. No legitimate service will ever ask for it. If someone obtains your phrase, they can steal all your digital assets permanently.
Follow these best practices:
- Write down the phrase on paper.
- Store it in a secure, offline location—such as a fireproof safe.
- Do not take screenshots or save it digitally in any form.
- Avoid cloud storage, email, messaging apps, or photos.
When prompted, click “Click here to reveal secret words,” then carefully write them down in order.
To confirm accuracy, MetaMask will ask you to re-enter the words in the correct sequence. This ensures you’ve backed them up properly.
Once verified, your wallet is ready to use.
Using Your MetaMask Wallet
Congratulations—you’ve successfully created a MetaMask wallet! You’ll now see your Ethereum address, account balance (initially zero unless funded), and transaction history.
To access your wallet at any time, simply click the fox icon in your browser toolbar. If you don’t see it immediately, check the puzzle-piece menu where extensions are grouped.
With MetaMask active, you can:
- Send and receive ETH and ERC-20 tokens
- Purchase NFTs on marketplaces like OpenSea
- Interact with DeFi platforms such as Uniswap or Aave
- Stake tokens, provide liquidity, or earn yield

Connecting MetaMask to dApps
Most decentralized applications prompt users to connect their wallets before use. Look for buttons labeled:
- “Connect Wallet”
- “Link Account”
- “Sign In with Ethereum”
For example, when visiting Uniswap, click “Connect a Wallet” in the top-right corner. A list of wallet options appears—select MetaMask, and you’ll be prompted to approve the connection.
Once connected:
- You retain full control over your funds.
- The dApp can only view your public address and request transaction approvals.
- No funds are transferred without your explicit consent.
Always verify the legitimacy of any platform before connecting. Scammers often create fake websites that mimic real dApps to steal credentials.
Critical Reminder: Never enter your recovery phrase into any website or application. MetaMask will never ask for it after setup.
