What does it mean to lock or protect a note?
Here is a list of available actions on a note and what they represent:
|Pin||Pinning a note will anchor it to the top of your list of notes, sorted
according to the global sort order (specified in your Options).
|Archive||Archiving a note will stash your note and hide it from your usual interface.
Archived notes can be found by choosing the reserved Archived view in the tags
panel. Archiving a note does not affect or improve performance, as the note is
still saved and loaded, but not displayed in the list of all notes or within a
particular tag. Archiving is useful for notes that no longer contain actionable
data, but want to be preserved for historical purposes. For example, if a note
contains a list of todos, and you've completed all the todos, archiving the note
would make sense.
|Lock||Locking a note will put it read-only mode, which means it can't be edited or
deleted until you unlock it. This is to prevent accidental modification of sensitive notes, like
passwords or credentials that aren't likely to change often.
|Protect||Protecting a note marks the note as sensitive, and makes it so that
additional authentication is required to view the note. The form of authentication used depends on your configuration.
You will be asked to authenticate with your passcode or biometrics (mobile) if you have that configured.
If you do not have a passcode or biometrics configured, you will be asked
to authenticate with your account password. If neither of those are configured and there is no protection source available,
the protected action will proceed without authentication. In addition, protecting a note will automatically hide its preview
in your list of notes.
|Preview||On web and desktop, selecting the Preview option will toggle whether to hide
or show the note preview in the list of notes. You can hide previews for a
particular note if you'd like to conserve vertical space in your list of notes,
or to hide sensitive data. However, we recommend Protecting a
note if you'd like to hide sensitive information.
|Move to Trash||Moving a note to the trash will mark the note as deleted, and remove it from
your interface. However, your note will still exist in your Trash, which you can
access from your list of Views. From the trash, you can restore the
note, or choose to delete it permanently. You can also empty the entirety of your
trash by choosing Options → Empty
Trash from the note editor panel.
