Existing Premium to Raspberry Pi

Apologies if this is in the wrong topic.

I have a Premium license for Plex have recently bought a Raspberry Pi 4 to use as my Plex server. My question is, (probably really stupid) when I get to the Plex login screen, should I use my existing user and password?

Thanks in advance and if this is in the wrong area, please direct me to a more appropriate area.

Yes.

You can have multiple servers on your account.

Use the username/e-mail address and password that has the Plex Pass.

Appreciate the rapid reply.
