Hi,
I just configured the Auth0 plugin for WP.
1 - I tried to log in on the ULP with the new password I created while setting up the plugin but received an “incorrect user/password”.
2 - I opted to reset the password but never received the email.
3 - I checked the User Management tab on the Auth0 dashboard and the user does exist.
4 - The logs read -
Type: Failed Change Password Request
Description: User does not exist.
… but really does exist 
Any help would be appreciated.
I’m new to Auth0, so still not familiarized with the platform. I see that the value for user_name is my email, but the username on WP is not the email. So if it’s trying to authenticate WP’s username with Auth0 user_name, it would make sense that the “user does not exist”.
Update: I figured out that it has something to do with the ULP using the wrong database connection. That’s why it can’t authenticate the user. I’m trying to figure out how to change it.
Update: I was able to disable the incorrect DB connection by going to Applications > [myapplication] > Connections > toggle connection off.
I was successfully able to log-in my WP site. Hope this helps someone.
