There are two ways to initially access your Coinbase Prime account. The method is determined by the email address that’s provided in the authorized user list on your business application and whether it's associated to an existing coinbase.com account.

Before starting work on MetaMask, you’ll need to have an account. The account can be created once you have installed it. For signing into the account using your PC, you will need to first visit the official website. Then, you’ll have to enter your login credentials. Hit the “Log In” tab to complete MetaMask sign in process.
