Currently Sophos Mobile Security is not part of the Sophos Container. Thus it is currently not possible to import a password safe file (that is stored in Sophos Workspace) by using the Sophos Mobile Security password safe import function. Currently the workaround is to open the Workspace and click on the password file to open the password safe with Mobile Security. Unfortunately the connection between Workspace and Mobile Security is lost as soon as the Workspace runs in background and that will also close the password safe. So every time you need your password safe, you have to re-open the password safe from Workspace again.
