Installing the MetaMask wallet
1.
MetaMask can be downloaded and installed on Chrome, iOS or Android by visiting the MetaMask website — https://metamask.io
2.
Upon downloading and installing the extension, you will be greeted by the MetaMask welcome page. To start, click [Get Started].
3.
If you are creating a new wallet, click [Create a Wallet].
4.
MetaMask will ask you if you want to share anonymous usage data and contribute to improving the extension. Accepting or rejecting this will not affect your use of MetaMask.
5.
Set a safe password, which you will use to log into your wallet in a browser. Note that this is not your seed phrase. A password is a safety measure which prevents other people using your device from accessing your wallet. If you forget your password, you can still access your cryptocurrency by using your seed phrase.
6.
Upon setting your password, MetaMask will present information about your wallet’s seed phrase. Don’t forget to read through the information if you are unfamiliar with how a crypto wallet works.
7.
You will now learn about your seed phrase. Click on the lock to see the words and write them down in the correct order. Keep the phrase in a safe place (preferably offline) and never share it with anyone. This string of words is the last backup of your wallet and its contents. To continue, click [Next].
8.
You will now have to repeat your seed phrase by selecting words from the bottom of the screen in the correct order. Once you are done, click [Confirm].
9.
Your MetaMask wallet is now ready for use. To see the wallet, click [All Done].
