If I use Login with Amazon, does that remove the need for account linking?

I'm a little confused with regards what I'm supposed to do for the Registration step of making a Smart Home Skill.I'm following the instructions on this page:

https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/steps-to-create-a-smart-home-skill#Finish%20Registering%20Your%20Skill%20in%20the%20Developer%20Portal

I'm supposed to account link users in my system to Amazon users but what if I use Login with Amazon on my "service" website. Does that remove the need for me to implement the logic which provides account linking support on my page? Also will Login with Amazon take care of the Oauth logic I need to implement that's described in the link below?

https://developer.amazon.com/appsandservices/solutions/alexa/alexa-skills-kit/docs/linking-an-alexa-user-with-a-user-in-your-system#h2_login

I apologize if my question is confusing. I've been reading through both those links and haven't completely wrapped my head around what exactly I'm supposed to implement and how. I figured I would try to speed up the process by asking here.

Thanks, Matthew

The short answer is no. Even if you use Login with Amazon for your website login, your service needs to provide an access token for the Alexa Skill to use when accessing your service on the user's behalf.

When account linking is initiated, Alexa sends the customer to login on your site. Whether you're using Login with Amazon, another service, or you've rolled your own login, once they have successfully logged into your site, you must provide an access token that the skill will store and use to access your service on the user's behalf.

You're an OAuth consumer when you use Login with Amazon to let a user create an account on your service. You're an OAuth provider when you use account linking to create a connection between your skill and your service.

So you're going to have two separate flows:

1: Account creation on your site using Login with Amazon (or another method).

2: Account linking between the account on your site and your Alexa Skill.

Hope I understood your question correctly and that this helps clarify things.

Thanks for your response Greg. Does that mean I need to implement my own Oauth server for account linking or can I use Amazon's Oauth server?

We actually wrote a blog post recently on how to use Login With Amazon and account linking in your app: https://developer.amazon.com/public/community/post/Tx3CX1ETRZZ2NPC/Alexa-Account-Linking-5-Steps-to-Seamlessly-Link-Your-Alexa-Skill-with-Login-wit
