By default, encryption keys have a reminder date one year after creation. The Reminder Date column displays a date to serve as a cue to rotate each encryption key.

When it is time to rotate an encryption key:

  • The key shows as disabled in the Status column of the Encryption Keys page.
  • The key is removed from the list of available keys shown in the Key dropdown of the Encrypted Workspaces pane.
  • Workspaces encrypted with that key remain encrypted, including backup versions of the workspace.
  • You can enable it.
