Once the app receives the token expired response, it sends the expired access token and the refresh token to obtain a new access token and refresh token. Once the access token expires, the server will send a token expired response. The app stores the refresh token safely.Įvery time the app sends a request to the server it sends the access token in the Authorization header and the server can identify the app using it. With refresh token-based flow, the authentication server issues a one-time use refresh token along with the access token. The idea of refresh tokens is that we can make the access token short-lived so that, even if it is compromised, the attacker gets access only for a shorter period.

So, why do we need both access tokens and refresh tokens? Why don’t we just set a long expiration date, like a month or a year for the access tokens? Because, if we do that and someone manages to get hold of our access token they can use it for a long period, even if we change our password! Now, let’s discuss why we actually need refresh tokens.

Once the refresh token expires, the client needs to authenticate with the authentication server once again and the flow repeats from step 1.

Steps 3 through 7 keep on repeating until the refresh token expires.The authentication component issues a new access token and refresh token.Once the access token expires, the client requests a new access token by providing the refresh token.After that, the client requests the resource endpoints for a protected resource by providing the access token.Then, the authentication component issues the access token and the refresh token.Now, we are going to introduce the refresh token to our authentication workflow: The lifetime of a refresh token is usually set much longer compared to the lifetime of an access token. When access tokens expire, we can use refresh tokens to get a new access token from the authentication component. Refresh tokens are credentials that can be used to acquire new access tokens. Refresh token-based authentication workflow

Once the access token expires, the client needs to authenticate with the authentication component once again and the flow repeats from step 1.

Steps 3 & 4 keep on repeating until the access token expires.

The resource endpoint validates the access token and provides a protected resource.

After that, the client requests the resource endpoint for a protected resource by providing the access token.

Then, the authentication component issues the access token.

First, the client authenticates with the authentication component by providing the credentials.

Let’s look at the JWT based authentication workflow that we implemented in the previous parts of this series:
