How to use AWS Cognito OAuth 2.0 Implicit Flow? This tutorial will discuss the OAuth flows in three parts, and you are now reading Part 1. I will show some examples on how we can use the different OAuth grants in Cognito and also retrieve the user info using the Access token.

The Implicit Flow bypasses the code exchange step, and instead the access token is returned in the query string fragment to the client immediately. In practice, there are only very limited cases in which this is necessary. Several major implementations (Keycloak, Deutsche Telekom, Smart Health IT) have chosen to avoid the Implicit Flow completely and use the Authorization Code flow instead. This is similar to the Implicit Grant from the OAuth2 spec, but it actually extends the OIDC Authorization Code Flow. It returns the ID Token and access token directly to the user agent as part of It looks like there are parameter changes that are being added to the traditional OAuth2 implicit grant type access token request.

OAuth is not a monolithic entity. There are so many flows it’s no wonder people still succumb to the temptation of Basic Auth. The first step always is choosing the right one.

The Implicit flow was a simplified OAuth flow previously recommended for native apps and JavaScript apps where the access token was returned immediately without an extra authorization code exchange step.

You obtain ID tokens as opposed to access tokens, which have a completely different intended use. The flow uses POST as opposed to placing tokens in URL fragments (as with SPAs) which can expose token bits to browser history attacks, redirect headers, and so on. Implicit Code Grant Type Flow. Implicit grant type flow (rightmost) is most similar to Authorization Code except Step #4 is not required, i.e., the OAuth server hands the key/access token directly back to the User/Browser This increases the attack surface of the system moderately since the key/access token in stored on the browser, which is more exposed to the internet than the App (backend).

Deciding which one is suited for your use case depends mostly on your application type, but other parameters weigh in as well, like the level of trust for the client, or the experience you want your users to have.

Understand OAuth2 quickly by comparing the flow diagrams for each grant type (Client Credential, Resource Owner Password Credential, Authorization Code, Implicit) side-by-side. All grant types have 2 flows: get access token & use access token. Only the former flow differs & we show the differences in the flow diagrams. The Auth0 Single-Page App SDK provides high-level API for implementing Authorization Code Flow with PKCE in SPAs. If your SPA doesn't need an Access Token, you can use the Implicit Flow with Form Post.
