An Android 13 device has clipboard auto-clear enabled. A user copies a password from a banking app. What is the platform behavior that protects this sensitive clipboard content?
- A.Android 13 clears the clipboard one minute after a copy from a sensitive field
- B.Android 13 automatically clears the clipboard after approximately one hour of inactivity
- C.Android 13 encrypts clipboard entries with a Keystore-backed wrapping key
- D.Android 13 blocks clipboard reads until the user taps a paste control
Why B is correct
Android 13 introduced automatic clipboard clearing: the system clears the primary clip after approximately one hour (3,600,000 ms) of inactivity. Separately, apps can flag clipboard content as sensitive via ClipDescription.EXTRA_IS_SENSITIVE, which masks the content preview in the clipboard UI - it does not change the clear timeout, so the one-minute claim is wrong. Clipboard contents are not Keystore-encrypted, so that choice is wrong. Background apps have been unable to read the clipboard since Android 10 regardless of any paste button, so that choice is wrong.
