First, let’s setup Metamask in the Chrome browser.
Open up a new Chrome browser window and navigate here
click on ‘ADD TO CHROME’ to install MetaMask plugin.
Next, enter a password, confirm the password, and then click Create for a new Ethereum account. This account allows you to send and receive Ether, ERC20 tokens and also allows you to deploy Smart Contracts.
MetaMask will now show you a 12 word recovery key (Seed) as below.
These 12 words are the only way to restore MetaMask accounts if you forget the password. It should be stored in a safe location, such as in a notebook or USB key kept in a safe. Then click on ‘I’VE COPIED IT SOMEWHERE SAFE’. The main screen of MetaMask will open as below.
That’s it you’ve just created a new Ethereum address using MetaMask! Your address can be found by hovering over the string of letters and numbers. It will say “copy to clipboard”, click on it and you will have your Ethereum address.
