Usage
Information
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.
