Not recieving emails for OTP

I did setup a passwordless connection, and its enabled for my current app. Now when a user tries to login, I can see in the logs Code/Link Sent with no errors, but the user is not recieving the code via email, note that email tests are working fine.

what could be the problem?

Hi @daniel32

Welcome to the Auth0 Community!

If you are using the default Auth0 email provider, we highly suggest that you setup a Custom External Email Provider, as the default provider is only intended for testing purposes.

As the logs do not show any failure logs, another suggestion would be to check in case the emails did not end up in a different folder instead of the email’s inbox folder ( for example in the Spam folder). It could also be useful to check if the email provider is not being blocked on the inboxes end.

Besides setting up a Custom Email Provider as mentioned above, I would also recommend reading through the following topic as well, since it offers additional details that could help with your issue at hand: Not Receiving OTP Emails – travel.world Domain Blacklisted in Auth0 Default Email Provider.

Hope this helped!
