-/**
- * @fileoverview
- *
- * 'settings-quick-unlock-authenticate' shows a password input prompt to the
- * user. It validates the password is correct. Once the user has entered their
- * account password, the page navigates to the quick unlock setup methods page.
- *
- * This element provides a wrapper around chrome.quickUnlockPrivate.setModes
- * which has a prebound account password (the |set-modes| property). The account
- * password by itself is not available for other elements to access.
- *
- * Example:
- *
- * <settings-quick-unlock-authenticate
- *     set-modes="[[setModes]]"
- *     profile-name="[[profileName_]]">
- * </settings-quick-unlock-authenticate>
