Open Google Chrome, Firefox or Brave on your computer and install the Metamask browser extension. Alternatively, download and install the Metamask App for iPhone or Android .
Open the app and choose “Create Wallet”. Create a username and password. Important: Make sure you safely record your Secret Recovery Phrase and store it somewhere secret and safe, as this is the only way to recover your wallet if you lose your device, or ever need to install it on another computer.
