Creating a new user account in Junos OS involves several specific steps within the [edit system login] configuration hierarchy. To establish a functional and secure user account, an administrator must first define the username and assign that user to a login class. Login classes are essential because they define the permissions and access levels for the user, such as super-user, read-only, or operator. Without a login class, a user would have no permissions to perform tasks within the CLI.

The second mandatory task is to configure an authentication method for the user, most commonly a password. This is typically done using the authentication plain-text-password command, which prompts the administrator to enter and confirm the secret string that the system then hashes and stores. While Junos also supports public-key authentication for SSH, a local password remains the standard for basic access control. It is important to note that SSH access is generally controlled at the system level under [edit system services] and does not need to be enabled on a per-user basis individually. Furthermore, allowing a user to bypass authentication is contrary to the Junos security model and is not a standard task in user account creation.
