OAuth 2.0 Refresh Token

tools.ietf.org/html/rfc6749#section-1.5

The Refresh Token grant type is used by clients to exchange a refresh token for an access token when the access token has expired.

This allows clients to continue to have a valid access token without further interaction with the user.
