Hi @MPMajorBob
Welcome to community!
Unfortunately, at this time each Roku account can only be associated with one Pandora account. So if someone logs in with their Pandora account on your Roku account the information will sync across all Roku devices for the the account.
The only way around this is to have a separate Roku account, but as you mentioned, other service may not be available depending on the account.
Sorry for any inconvenience around this!
