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 conguration le and by default are displayed in the
encrypted form when the conguration 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 le.
The string of asterisks is the same length as the encrypted string for that line of conguration. To verify that you
have successfully obscured passwords and keys, use the show running-config command orshow
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.
