Hi @nephigrant,
Welcome to the Community!
We are unable to recover a deleted tenant, like you have seen is in our docs and the warnings presented when you go to delete a tenant. It’s our policy for the sake of data security and compliance.
If you are in need of a very specific name we recommend using a custom domain like login.example.com, or if you are a free customer and don’t have access to custom domains you could use example-prod@auth0.com.
Best,
Dan
