  • The SUSE operating system must require the change of at least eight (8) of the total number of characters when passwords are changed.

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
