For Switch Engine devices only, use device credentials to set up login information for root or read-only administrators, change the name and password of the root admin, or add a read-only admin to a device. Device-level credentials offer access to devices through Telnet, SSH, or console connections.
A root admin has complete privileges, which include the ability to add, modify, and delete other administrators, and to reset the configuration. A read-only admin can view settings but cannot add, modify, or delete them. You can require that an admin be prompted for a password before accessing high-level privileged CLI commands.
