The last Login with Amazon blog post described how to set up the Login with Amazon plugin for Wordpress. In this post we are going to look at the steps you can take if you receive the following error message when trying to log in:

In this case, the login process at Amazon seems to work, but when the pop-up window closes, you get the error message. Even more perplexing, you will have what appears to be a valid access token in the URL:

https://www.example.com/wp-login.php?amazonLogin=1&access_token=Atza[...] &token_type=bearer&expires_in=3600&scope=profile&state=[...]
When you have this specific issue, the likely reason is that you don't have curl set up properly.

There are a number of plugins available to help you integrate Login with Amazon (LwA) into your website. One of these is the LwA plugin for WordPress. If you allow users besides yourself to log in to your WordPress installation, it can be useful to let them use their Amazon credentials to log in, giving them one less ID/password combination to remember.

It's quite simple. Install it, activate it, configure it, and it will add a "Login with Amazon" button below your regular site login form. Here's how that works:

Install it

In the Plugins section of your WordPress control panel, select “Add New”. On the “Add New page”, search for "Login with Amazon".

Login with Amazon (LwA) allows your customers to log in to your website or app using their Amazon credentials. LwA uses the OAuth 2.0 protocol making integration easy, and allows you to provide a more personalized user experience such as greeting visitors by name or displaying customized offers based on zip codes.

Depending on the permissions you request as part of this authentication (and what the user approves), LwA returns information you can use to connect to different Amazon APIs and obtain information about the user, perform tasks on their behalf, and/or incorporate Amazon services into your interactions with them.

The JavaScript SDK for the web use case

When a user opts to use Login with Amazon to log into your site, you have to send them to an Amazon controlled page where they enter their email and password. This provides assurance to the user that you are not peeking at their password. When a user completes a login and approves the permissions you requested, the main browser window is redirected to a URL of your designation with information embedded in the URL.

There is one use case, involving the JavaScript SDK for the web and an Implicit Grant (where the "response_type" is "token"), that returns an access token with a URL fragment (#x=y) rather than a query string (?x=y). Why does this happen?
