+
 When nil, the input method will be disabled and an ordinary keyboard
 will be displayed in its place.
+
 When the symbol `action', the input method will insert text directly, but
 will send `return' key events instead of inserting new line characters.
 Any other value means that the input method will insert text directly.
 
+When the symbol `password', an input method capable of ASCII input will
+be enabled, and will not save entered text where it will be retrieved
+for text suggestions or other features not suited to handling sensitive
+information, in addition to reporting `return' as when `action'.
+
 If you need to make non-buffer local changes to this variable, use
 `overriding-text-conversion-style', which see.
