Can multiple user accounts/passwords be stored on MC92N0-G (WinCE)?

We are interested in purchasing 5 MC92N0-G (WinCE) scanners to replace our laptop/USB Scanner hardware.

I've never used a WiFi scanner and need to know if it is possible to store approximately 20 user accounts / passwords locally on each scanner.  My plan would be to replicate this to each scanner.

By authenticating a user, we can transmit the username + partnumber to the application server with each scanned part, e.g.: cbeltran-1111111111.

Questions:

1) Is it possible to store up to 20 user accounts/passwords on the MC920N0-G (WinCE)?

2) If the answer to #1 is 'yes', is it necessary to create a configuration profile (lan settings, etc.) for each user or would all of the user accounts use a single configuration profile?

Thank you
