Authenticate admin as end user

Hi!

I need my administrators to be able to access my frontend just like an end user - with their admin account. Is there any way to create an end user on admin creation?

I can only find information on how to authenticate through the API as an end user, but not as an admin.

Simply put: I either need all admins to be able to authenticate as end users, or certain end user to be able to login as admins in the admin panel.

Thanks in advance!
