access 2 or more receivers with the same login

I can access 2 or more receivers with the same login?
if the answer is no, there is a package that allows it?

No, you can't. Dual-login option is available only for 1 receiver with 2 tuners onboard. Read the corresponding topic.
For 2 or more receivers, you will need 2 or more logins.
