Root Password Overview

The root user has complete privileges to operate and to configure the Juniper Networks device, perform upgrades, and manage files in the file system. Initially, the root password is not defined on the device. To ensure basic security, you must define the root password during initial configuration. If your device does not have a defined root password, you cannot commit configuration settings on the device.

The root password must meet the following conditions:

  • Be at least six characters long. You can include most character classes (alphabetic, numeric, and special characters) in a password, except control characters.

  • Contain at least one change of case or of character class.
