Your Gateway to the Decentralized Web
Learn how to securely log in to decentralized applications using your MetaMask wallet. A complete guide for beginners and advanced users alike.
Get StartedMetaMask is a cryptocurrency wallet and gateway to blockchain apps. It allows you to store, send, and receive Ethereum and other ERC-20 tokens. More importantly, it enables you to interact with decentralized applications (dApps) on the Ethereum blockchain.
With over 30 million users worldwide, MetaMask has become the most popular Ethereum wallet and the primary tool for accessing the decentralized web.
Visit the official MetaMask website or your browser's extension store to download and install the MetaMask extension.
Click "Create a Wallet" and follow the setup process. Make sure to create a strong password for your wallet.
Write down your 12-word seed phrase and store it in a secure location. This is your backup to restore your wallet.
MetaMask will ask you to confirm your seed phrase by selecting the words in the correct order.
Navigate to a decentralized application that supports MetaMask login.
Look for a "Connect Wallet" or "Login with MetaMask" button on the website.
MetaMask will open a popup asking you to authorize the connection. Review the permissions and click "Connect".
Some dApps require you to sign a message to verify ownership of the wallet. This doesn't cost any gas fees.
No passwords to remember. Your private keys are stored securely on your device.
Built-in browser for exploring decentralized applications directly from the wallet.
Easily manage multiple Ethereum accounts and ERC-20 tokens in one place.
Switch between Ethereum mainnet, testnets, and custom networks with one click.
Your seed phrase is the key to your wallet. Never share it with anyone or enter it on any website.
For maximum security, connect a hardware wallet like Ledger or Trezor to your MetaMask.
Always check the URL before connecting your wallet. Scammers create fake websites to steal funds.
Regularly update your MetaMask extension to benefit from the latest security patches.
Make sure the extension is installed and enabled. Refresh the page and try again.
Try increasing the gas limit or gas price. You can also try resetting your account in Advanced Settings.
Ensure you're connected to the correct network that the dApp requires (e.g., Mainnet, Ropsten, etc.).
