 **Access token**: An access token is a security token that's issued by an [authorization server](developer-glossary.md#authorization-server) as part of an [OAuth 2.0](active-directory-v2-protocols.md) flow. It contains information about the user and the resource for which the token is intended. The information can be used to access web APIs and other protected resources. Access tokens are validated by resources to grant access to a client app. To learn more about how the Microsoft identity platform issues access tokens, see [Access tokens](access-tokens.md).
 
-**Refresh token**: Because access tokens are valid for only a short period of time, authorization servers will sometimes issue a refresh token at the same time the access token is issued. The client application can then exchange this refresh token for a new access token when needed. To learn more about how the Microsoft identity platform uses refresh tokens to revoke permissions, see [Token revocation](access-tokens.md#token-revocation).

 **ID token**: ID tokens are sent to the client application as part of an [OpenID Connect](v2-protocols-oidc.md) flow. They can be sent alongside or instead of an access token. ID tokens are used by the client to authenticate the user. To learn more about how the Microsoft identity platform issues ID tokens, see [ID tokens](id-tokens.md).
