If you're using a mobile device, please download the official MetaMask app for iOS or Android from the App Store or Google Play. Always verify that the developer is "MetaMask."
Installation Steps from the Official Site
Below is a guide to the general steps for safely installing MetaMask. Always download from the official site (metamask.io) and be extremely cautious of phishing sites.
Access the Official MetaMask Website
Type "metamask.io" directly into your browser's address bar to access the official MetaMask website. We strongly recommend typing the URL directly as links from search engines may lead to fake sites.
Click the Download Button on the Official Site
Click the "Download" button on the official site's homepage. Your browser will be automatically detected and you will be redirected to the appropriate official extension store.
Verify the Developer and Add from the Official Store
In the Chrome Web Store, Firefox Add-ons, or your browser's official extension store, make sure to verify that the developer is "MetaMask" before clicking the "Add" button.
Confirm Installation is Complete
Once installation is complete, a fox icon will appear in your browser's toolbar. Click this icon to open MetaMask and begin the initial setup following the official instructions.
Beware of Phishing Scams
Many fake websites and extensions impersonate MetaMask. Always download from the official site (metamask.io) and verify in the extension store that the developer is "MetaMask." This site (MetaDetails) is not a MetaMask distributor.
Wallet Setup
After installation, when you first open MetaMask, the wallet setup screen will appear. Below is an explanation of the general setup steps. Please refer to the official help center for details.
Creating a New Wallet
Select "Create a New Wallet"
Select the "Create a new wallet" option on the initial screen. If you already have a wallet, choose "Import existing wallet."
Set a Strong Password
Create a strong password of at least 8 characters. This password will be used to unlock MetaMask in your browser. We recommend combining uppercase letters, lowercase letters, numbers, and symbols.
Securely Record Your Secret Recovery Phrase
A 12-word Secret Recovery Phrase will be displayed. This is the only way to recover your wallet. Write it down on paper and store it safely offline. Never save it digitally or share it with anyone.
Confirm Your Phrase
Enter your recorded Secret Recovery Phrase in the correct order to confirm. This verifies that you have accurately recorded the phrase.
Security Tip
Consider storing your Secret Recovery Phrase engraved on a fireproof and waterproof metal backup tool. This can protect your phrase from fire and water damage.
Security Tips
To use MetaMask safely, please always practice the following security measures.
Essential Security Measures
Protect Your Secret Recovery Phrase: Store your 12-word phrase offline in multiple secure locations. Never take screenshots, save to cloud storage, or send via email.
Be Vigilant Against Phishing Scams: Official MetaMask will never ask for your Secret Recovery Phrase via email or website. If you receive such a request, it is 100% a scam.
Use Official Channels: MetaMask support is only provided through the official website (metamask.io) and the in-app help center. They do not provide support via DMs on social media.
Regular Security Checks: Regularly check connected sites and disconnect from any sites you no longer use. You can check "Connected sites" in MetaMask settings.
Absolutely Follow This
Anyone who knows your Secret Recovery Phrase can access all the assets in your wallet. No company or support representative, including MetaDetails, will ever ask for your Secret Recovery Phrase. If asked, it is 100% a scam.
