[MlMt] iCloud accounts require an app specific password starting June 15th

[Bob Stern]

FYI, a counter-intuitive aspect of app-specific passwords is that they need not be specific to a single application.  Although Apple can issue up to 25 different app-specific passwords for a given iCloud account, the account owner can elect to use a single app-specific password for multiple applications.

As Benny states in his blog post, an application is not restricted to a specific subset of iCloud data, which seems to defeat the purpose of app-specific passwords.  The only advantage I can think of for creating different passwords for different applications is it enables you to revoke one application's access to iCloud if, for example, you stop using the application or the application is acquired by a company with notorious privacy practices.
