Hi @joe.anon,
As a workaround, can you create a new account with your work email using a suffix, such as username+suffix@company.domain? The suffix could be something like +admin1, for example.
If this works for you, we recommend:
- Creating a couple of Super Admin users in your org.
- Make sure all admins are registered for MFA.
In addition, follow this guide, Enable Terraform access for your Okta org, to make sure you have access to a Terraform config in the event you are locked out.
