The Ory Kratos registration flow does not explicitly mention whether you can register more than one email with the same password. However, it does provide a customizable registration flow that allows you to define custom fields and validation rules through the identity schema. The registration flow consists of methods such as

password

,

oidc

, and

webauthn

. For the

password

method, Ory Identities uses the Identity Schema defined in

identity.default_schema_id

to generate a list of form fields and add it to the Registration Flow. If you want to allow multiple emails to be registered with the same password, you would need to customize the identity schema and the validation rules to allow this. However, it's important to note that allowing multiple accounts to share the same password could potentially weaken the security of your application. For more information, you can refer to the [Ory Kratos User Registration Documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-registration) and the [Ory Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api).
