+
+    A user-agent-based application is a public client in which the
+    client code is downloaded from a web server and executes within a
+    user-agent (e.g. web browser) on the device used by the resource
+    owner.  Protocol data and credentials are easily accessible (and
+    often visible) to the resource owner.  Since such applications
+    reside within the user-agent, they can make seamless use of the
+    user-agent capabilities when requesting authorization.
+
+    The implicit grant type is used to obtain access tokens (it does not
+    support the issuance of refresh tokens) and is optimized for public
+    clients known to operate a particular redirection URI.  These clients
+    are typically implemented in a browser using a scripting language
+    such as JavaScript.
+
+    As a redirection-based flow, the client must be capable of
+    interacting with the resource owner's user-agent (typically a web
+    browser) and capable of receiving incoming requests (via redirection)
+    from the authorization server.
+
+    Unlike the authorization code grant type in which the client makes
+    separate requests for authorization and access token, the client
+    receives the access token as the result of the authorization request.
+
+    The implicit grant type does not include client authentication, and
+    relies on the presence of the resource owner and the registration of
+    the redirection URI.  Because the access token is encoded into the
+    redirection URI, it may be exposed to the resource owner and other
+    applications residing on the same device.

+
+    Note: The lines illustrating steps (A), (B), and (C) are broken into
+    two parts as they pass through the user-agent.
+
+    Figure 3: Authorization Code Flow
+
+    The flow illustrated in Figure 3 includes the following steps:
+
+    (A)  The client initiates the flow by directing the resource owner's
+         user-agent to the authorization endpoint.  The client includes
+         its client identifier, requested scope, local state, and a
+         redirection URI to which the authorization server will send the
+         user-agent back once access is granted (or denied).
+
+    (B)  The authorization server authenticates the resource owner (via
+         the user-agent) and establishes whether the resource owner
+         grants or denies the client's access request.
+
+    (C)  Assuming the resource owner grants access, the authorization
+         server redirects the user-agent back to the client using the
+         redirection URI provided earlier (in the request or during
+         client registration).  The redirection URI includes an
+         authorization code and any local state provided by the client
+         earlier.
+
+    (D)  The client requests an access token from the authorization
+         server's token endpoint by including the authorization code
+         received in the previous step.  When making the request, the
+         client authenticates with the authorization server.  The client
+         includes the redirection URI used to obtain the authorization
+         code for verification.
+
+    (E)  The authorization server authenticates the client, validates the
+         authorization code, and ensures that the redirection URI
+         received matches the URI used to redirect the client in
+         step (C).  If valid, the authorization server responds back with
+         an access token and, optionally, a refresh token.
+
+    OAuth 2.0 public clients utilizing the Authorization Code Grant are
+    susceptible to the authorization code interception attack.
+
+    A technique to mitigate against the threat through the use of Proof Key for Code
+    Exchange (PKCE, pronounced "pixy") is implemented in the current oauthlib
+    implementation.

+
+    The implicit grant type is used to obtain access tokens (it does not
+    support the issuance of refresh tokens) and is optimized for public
+    clients known to operate a particular redirection URI.  These clients
+    are typically implemented in a browser using a scripting language
+    such as JavaScript.
+
+    Unlike the authorization code grant type, in which the client makes
+    separate requests for authorization and for an access token, the
+    client receives the access token as the result of the authorization
+    request.
+
+    The implicit grant type does not include client authentication, and
+    relies on the presence of the resource owner and the registration of
+    the redirection URI.  Because the access token is encoded into the
+    redirection URI, it may be exposed to the resource owner and other
+    applications residing on the same device::

+
+   Note: The lines illustrating steps (A) and (B) are broken into two
+   parts as they pass through the user-agent.
+
+   Figure 4: Implicit Grant Flow
+
+   The flow illustrated in Figure 4 includes the following steps:
+
+   (A)  The client initiates the flow by directing the resource owner's
+        user-agent to the authorization endpoint.  The client includes
+        its client identifier, requested scope, local state, and a
+        redirection URI to which the authorization server will send the
+        user-agent back once access is granted (or denied).
+
+   (B)  The authorization server authenticates the resource owner (via
+        the user-agent) and establishes whether the resource owner
+        grants or denies the client's access request.
+
+   (C)  Assuming the resource owner grants access, the authorization
+        server redirects the user-agent back to the client using the
+        redirection URI provided earlier.  The redirection URI includes
+        the access token in the URI fragment.
+
+   (D)  The user-agent follows the redirection instructions by making a
+        request to the web-hosted client resource (which does not
+        include the fragment per [RFC2616]).  The user-agent retains the
+        fragment information locally.
+
+   (E)  The web-hosted client resource returns a web page (typically an
+        HTML document with an embedded script) capable of accessing the
+        full redirection URI including the fragment retained by the
+        user-agent, and extracting the access token (and other
+        parameters) contained in the fragment.
+
+   (F)  The user-agent executes the script provided by the web-hosted
+        client resource locally, which extracts the access token.
+
+   (G)  The user-agent passes the access token to the client.
+
+    See `Section 10.3`_ and `Section 10.16`_ for important security considerations
+    when using the implicit grant.

+    to the entity body of the HTTP response with a 200 (OK) status code:
+
+    access_token
+            REQUIRED.  The access token issued by the authorization server.
+    token_type
+            REQUIRED.  The type of the token issued as described in
+            `Section 7.1`_.  Value is case insensitive.
+    expires_in
+            RECOMMENDED.  The lifetime in seconds of the access token.  For
+            example, the value "3600" denotes that the access token will
+            expire in one hour from the time the response was generated.
+            If omitted, the authorization server SHOULD provide the
+            expiration time via other means or document the default value.
+    refresh_token
+            OPTIONAL.  The refresh token which can be used to obtain new
+            access tokens using the same authorization grant as described
+            in `Section 6`_.
+    scope
+            OPTIONAL, if identical to the scope requested by the client,
+            otherwise REQUIRED.  The scope of the access token as described
+            by `Section 3.3`_.
+
+    The parameters are included in the entity body of the HTTP response
+    using the "application/json" media type as defined by [`RFC4627`_].  The
+    parameters are serialized into a JSON structure by adding each
+    parameter at the highest structure level.  Parameter names and string
+    values are included as JSON strings.  Numerical values are included
+    as JSON numbers.  The order of parameters does not matter and can
+    vary.
+
+    :param body: The full json encoded response body.
+    :param scope: The scope requested during authorization.
+
+    For example:

+
+        A key to OAuth 2 security and restricting impact of leaked tokens is
+        the short expiration time of tokens, *always ensure the token has not
+        expired!*.
+
+        Two different approaches to scope validation:
+
+            1) all(scopes). The token must be authorized access to all scopes
+                            associated with the resource. For example, the
+                            token has access to ``read-only`` and ``images``,
+                            thus the client can view images but not upload new.
+                            Allows for fine grained access control through
+                            combining various scopes.
+
+            2) any(scopes). The token must be authorized access to one of the
+                            scopes associated with the resource. For example,
+                            token has access to ``read-only-images``.
+                            Allows for fine grained, although arguably less
+                            convenient, access control.
+
+        A powerful way to use scopes would mimic UNIX ACLs and see a scope
+        as a group with certain privileges. For a restful API these might
+        map to HTTP verbs instead of read, write and execute.
+
+        Note, the request.user attribute can be set to the resource owner
+        associated with this token. Similarly the request.client and
+        request.scopes attribute can be set to associated client object
+        and authorized scopes. If you then use a decorator such as the
+        one provided for django these attributes will be made available
