Hi @carl.huynh,
Welcome to the Auth0 Community!
When a user changes their email address multiple times, Auth0 exports the most recent/current email address associated with the user’s account. The previous email addresses are not retained or exported. When the email is changed, it is updated in the primary connection for that user.
If the user has linked accounts, you may need to update the email for secondary connections separately using the Management API. Email verification is crucial when allowing users to change their email addresses to ensure they have access to the new email.
- Reusing a Previous Email Address after it is Changed to a New Email Address
- Cannot login with updated email for user with linked account
- Verify Emails using Auth0
Also, please check these articles explaining how to get or export users from Auth0 tenants:
Thanks,
Timotei
