Step 1. Install MetaMask on your browser
Visit https://metamask.io/
Hit "Download" in the menu bar.
Click “Install MetaMask for Chrome”. You will be directed to the Chrome Web Store.
Note: This guide will focus on the chrome browser, however the process is similar for other browsers.
Click “Add to Chrome”.
On the pop up, click “Add extension”.
After adding MetaMask Extension, MetaMask will automatically open. You can also make sure it's easily accessible in your toolbar by clicking the jigsaw icon in the top-right of the screen, and hitting the pin icon.
Step 2. Create an account
Click on the extension icon in the upper right corner to open MetaMask.
To install the latest version and be up to date, click Try it now.
Click Continue.
You will be prompted to create a new password. Click Create.
Proceed by clicking Next and accept the Terms of Use.
Click Reveal Secret Words. There you will see a 12 words seed phrase. This is really important and usually not a good idea to store digitally, so take your time and write it down.
Verify your secret phrase by selecting the previously generated phrase in order. Click Confirm.
And that’s it; now you have created your MetaMask account successfully.
