BrowZine Account - This account is free to use and creation of this account allows an individual user to customize the contents of My Bookshelf, My Articles and to access the options menu in BrowZine web to provide options such as being able to clear all unread articles and other functions. The BrowZine Account, depending on your library, might also be used to authorize the BrowZine Pairing Service, a service utilized by some libraries to provide remote authentication specifically for BrowZine on mobile devices.
Library Login Credentials - If this is available at your institution, your library utilizes a proxy service for remote authentication that BrowZine can interact with in a responsible manner. BrowZine can store user credentials in an encrypted manner in this area which provides access to content. Some libraries may not see this option because they use systems like a VPN service or have no remote authentication options.
Citation Services - Citation services use credentials via OAuth which means that once you have signed in at the appropriate service site, a secure token from that service is stored within BrowZine so that the app does not need to ask you to manually sign in over and over again. All of the BrowZine platforms also feature an option to "forget" this token so that BrowZine no longer can auto-sign in to the service when exporting citations.
Email Accounts - BrowZine offers a function to email a citation to yourself a colleague which requires the use of an email client on your mobile device or desktop computer. There is no email client built into BrowZine so to utilize this function you must have an email service available on that device which you can utilize.
