You specify the passwords for your VMware Cloud Foundation system's internal accounts as part of the bring-up procedure. You can also modify the passwords for these accounts using RESTful API calls.

You can update or rotate the password for the root and mystic users of the VxRail Manager and the root user of ESXi hosts using the SDDC Manager UI. To update or rotate the passwords for other users refer to the Dell EMC VxRail documentation.

To provide the optimal security and proactively prevent any passwords from expiring, you should rotate passwords every 80 days.
