To set up MetaMask on a mobile device, you will need to visit either Google Play or the App Store. Desktop computer users will need to download the extension or add-on for their browser of choice. MetaMask is currently available for iOS, Android, Chrome (or Brave), Firefox, and Microsoft Edge. Here are the official download links for [MetaMask](https://metamask.io/): * [App Store (iOS)](https://apps.apple.com/us/app/metamask/id1438144202) * [Google Play (Android)](https://play.google.com/store/apps/details?id=io.metamask) * [Chrome (or Brave)](https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn) * [Firefox](https://addons.mozilla.org/en-US/firefox/addon/ether-metamask/) * [Microsoft Edge](https://microsoftedge.microsoft.com/addons/detail/metamask/ejbalbakoplchlghecdalmeeeajnimhm?hl=en-US) ![If you are adding the MetaMask extension on desktop you will be prompted with a notification similar to the above.](https://storage.googleapis.com/papyrus_images/1ae2b0d4752319addfc912c0552bfaafd05a5984bcc06f20ae0cd09c0183aebe.png) If you are adding the MetaMask extension on desktop you will be prompted with a notification similar to the above. ### Getting Started MetaMask has an on-screen setup tutorial for all users on every supported browser. Follow the instructions, read through the terms, and click “I Agree” to continue the setup process. ### Create Your Wallet The first step in getting set up with MetaMask is creating a wallet. Click on the “Create a Wallet” button. You will then need to create a password with a minimum of eight characters that you will use to log in to the browser extensions or add-on.  ### Secret Backup Phrase Your Secret Backup Phrase is a way to easily backup and restore your account at any time. It consists of twelve words in a particular sequence. It is essential to memorize this, write it down on a piece of paper and place it in a safe place, or store it in a password manager like [1Password](https://1password.com/) or [LastPass](https://www.lastpass.com/).  Without your Secret Backup Phrase, it will be impossible to restore your account. You can download the phrase and store it on an external encrypted hard drive or storage device for added security. We do not recommend copy and pasting it into a notepad and leaving it on your desktop. If your computer gets stolen, hacked, or someone finds the file, someone can easily log in to your MetaMask wallet. Confirm your Secret Backup Phrase on the next on-screen prompt when you have it safely stored. This step ensures you have the correct phrase on hand in case you need to restore your account. After confirming your Secret Backup Phrase, click on the “All Done” button. You have now created a MetaMask wallet and are connected to the Ethereum Mainnet.  Those are the complete steps for how you install and set up MetaMask on PC and Mobile for Chrome, Firefox, Microsoft Edge, iOS, and Android. How to find your Ethereum address in MetaMask --------------------------------------------- After installing MetaMask in your browser and the initial setup process is complete, you can click the MetaMask extension or add-on icon from the toolbar. If you are on mobile, just launch the application. The MetaMask interface should now be visible to you, and you will see a string of numbers and letters under “Account 1” near the top of the window. That is your Ethereum address, and you can click on it to copy it to your clipboard. ![](https://storage.googleapis.com/papyrus_images/cf5c31208a8b642c47c34e9c0c67aa1c959de70b796705be295619de4dab31c8.png) How to Sync Metamask Across Devices ----------------------------------- MetaMask allows you to sync your wallets across multiple devices.
