After I create an identity, how do I initialize his password?

you are probably looking for https://www.ory.sh/kratos/docs/admin/managing-users-identities#invite-a-user

In our scenario, passwords are set by administrators, not users themselves This scene is not supported for now, is it?

you then either have to wait for https://github.com/ory/kratos/pull/1963 or use the recovery flow as an administrator

Our primary scenario is the private cloud, so administrators have maximum access

not only access, but also passwords could leak to bash history, logs, ... and have to be safely transferred (i.e. not slack, email, ...) just a friendly reminder to remember pitfalls there

Thank you for your reminder Our scenario is relatively simple. In a private cloud environment, the administrator manages users and delivers accounts Then a common user logs in to the system using the delivered account and password We then integrate permission-related controls with keto’s capabilities
