+Input types:

+- "Plain" - a normal option which is shown in clear text

+- "Date" - A Date input which can produce a date string in a user-defined format.
+- "Plain Text with Password Input" - an option which is obscured at user input time, and the value of which is not stored in the database, but is exposed in scripts and commands. See [secure-options](#secure-options).
+- "Secure Remote Authentication" - a secure option which is used only for remote authentication and is not exposed in scripts or commands. See [secure-remote-authentication-options](#secure-remote-authentication-options).

 This variable also allows you to add or remove days as you can see below.
