After migrating Windows device(s) from Symantec Endpoint Protection Small Business Edition (SEP SBE) to Symantec Endpoint Protection Cloud (SEP Cloud), users are prompted to change their Windows passwords.
By default, SEP Cloud enforces password requirements as part of its security policies. This is a feature that was not present in the SEP SBE product.
To improve user and device security, Symantec recommends allowing SEP Cloud to manage password strength in environments where there are no other means to do so.
Administrators who wish to disable or modify this setting may do so by editing or creating a new Security Policy in the SEP Cloud portal and assign it to their policy groups.

Note: To prevent users from needing to change their passwords immediately after migration, it is recommended administrators modify their security policies before the devices themselves are migrated. By default, administrators will have some time to make modifications after their SEP Cloud account leaves preview mode.
The password setting modifies the Password Policy in the Windows Local Security Policy. You may need to change those policies to return to original settings.
