Overview

Editorial synthesis with inline references and a source ledger when citations are available.

iPadOS 16.3 added physical Security Keys as an optional second factor for Apple ID and support for the second-generation HomePod. It also addressed Freeform strokes that could disappear from shared boards.[1]

Additional corrections covered Siri music requests and other reliability or security work described by Apple. This was a smaller update than 16.2, with account protection and targeted fixes forming the documented center of the release.[2][3]
