Error - user with the same email

[BlackStar]

Please help!! I have successfully connected my Wordpress install to Auth0. I am having issues logging in for one specific user, all others are working. I am getting the error that there is a user with the same email.

I read in another thread: This error happens when an incoming successful Auth0 login has the same email address as an existing WordPress user but a different Auth0 user ID. This can happen if you already have a DB user and then use Google to login with the same email address but don’t have account linking on.

This is exactly what happened. Now, how do I fix it???

Hi @BlackStar ,

Welcome to the Auth0 Community!

The following FAQs and article talk about how to implement the account linking feature.

How to Use the Auth0 Account Link Extension to Link Accounts

Problem statement: Auth0 supports the linking of user accounts from various identity providers. This allows users to authenticate from any of their accounts and still be recognized by your app and associated with the same user profile. Auth0 has an easy-to-use extension to help users link accounts. With this extension installed, when users log in to a web application with the same email but a different type of connection, they can choose to link the accounts. Solution: https://auth0.com/docs…

Account Linking Using Post-Login Actions

Problem Statement Is it possible to link user accounts using a Post-Login Action? Solution Actions can be used to call the Management API to link user accounts. Auth0 does not automatically change to the correct primary user after Account Linking, so it must be changed within the Actions code upon successful Account Linking with api.authentication.setPrimaryUser(). The process for linking accounts in actions, along with an example can be found here:

@How to Use the Auth0 Account Link Extension to Link Accounts

Create a testing React Sample SPA, download the project, add domain, clientId, and audience in the auth_config.json file

Thank you, I was able to install the extension and rule. However, when I attempt to login I am still getting the same error. I see the user in Auth0 with both applications listed and it is counting the logins, but wordpress throws the error and I am not actually logged in. Is there a way to manually link the particular users with different Auth IDs?
