Dell Configuration Guide for the S4048–ON System 9.14.2.6

By default, the service password-encryption command stores encrypted passwords. For greater security, you can also use the service obscure-passwords command to prevent a user from reading the passwords and keys, including RADIUS, TACACS+ keys, router authentication strings, VRRP authentication by obscuring this information. Passwords and keys are stored encrypted in the configuration file and by default are displayed in the encrypted form when the configuration is displayed. Enabling the service obscure-passwords command displays asterisks instead of the encrypted passwords and keys. This command prevents a user from reading these passwords and keys by obscuring this information with asterisks.

Password obscuring masks the password and keys for display only but does not change the contents of the file. The string of asterisks is the same length as the encrypted string for that line of configuration. To verify that you have successfully obscured passwords and keys, use the show running-config command or show startup-config command.

If you are using role-based access control (RBAC), only the system administrator and security administrator roles can enable the service obscure-password command.

To enable the obscuring of passwords and keys, use the following command.

DellEMC(config)# service obscure-passwords
