Version Description

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
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.
