I am writing a memo and here's my first sentence: <br/><br/><b>Access to the system is through a logonid and a password.</b><br/><br/>Could I use any of these for my second sentence? <br/><br/>1. Operations, Technical Support and Network each use a separate set of logonid and password. <br/><br/>2. Separate sets of logonids and passwords are used by Operations, Technical Support and Network. <br/><br/>I wish you could give me a model structure for this type of sentence.
