What are Access and Refresh Tokens?
Coinbase implemented an optional security feature of OAuth2 that uses the refresh tokens. The access token and refresh token are obtained in the app after the first authentication.
The access token is used to authenticate requests and expires after about two hours. When it is expired, the refresh token comes into play, allowing us to get a new access token and refresh token.
