Hello Community,

I am facing the duplicate user issue when enabling SSO (google signup) along with normal Auth0 signup.

Please guide me on how to restrict the user for duplicate user email address entries.

Hi @admin_bonusbinder

Welcome to Auth0 Community !!!

This is a normal behavior within auth0. When user signups with different connections in your case it is DB and social then Auth0 consider these as two different users.

To link these users you can use account linking. User Account Linking

Hope it helps

Jeff

Hi ,

currently we are using the free plan which does not include user account linking feature.

Is there any way we can do the validation by using action triggers with pre-registration event.

Please let us know your inputs.
