Passwordless email and multiple domains

Currently, I have a single page application that talks to our backend REST API. We are using the passwordless login option and we have a custom domain to prevent popup blockers from blocking the auth0 popup. The problem I have is that I have another domain that I need to talk to our backend server and also need to use the passwordless login option. How can I enable the second custom domain to talk to the same resource backend and not trigger popup blockers. As far as I understand you can only have one custom domain per tenant. Any help would be greatly appreciated. Thanks!

Hi @michael.suzuki,

Welcome to the Auth0 Community!

Unfortunately, we do not currently support using multiple custom domains on a single tenant. If you want to use a second custom domain, you must use another tenant.

I recommend checking out this knowledge solution for more details, and consider upvoting this feedback to support multiple custom domains.

Thanks,

Hi @rueben.tiow,

The first link you gave me is not an actual solution, but actually points to the second feedback link that has been open for over three years now wiithout any movement.

Even if I create a second tenant (which I have) how do I create a new application that is authorized against my API that lives in my other tenant? I see no clear means to do that via your API or via the dashboard. If I was able to do that it would likely solve my issue.

Thank you,

Michael

Hi @rueben.tiow ,

Any further updates? I still would like to know how to hook up my application in one tenant to an api in a different tenant.

Thanks,

Hi @michael.suzuki,

Thanks for the responses.

Unfortunately, that is part of the limitation when using multiple tenants and domains. Because your API lives in your initial tenant, your secondary tenant won’t be able to authorize against it using passwordless.

Thanks,
