Usage Guidelines
Usage Scenario
This command can change the limit on the password length. A longer password length makes the password more complex and improves device security.
Precautions
The set password min-length command limits the length of all passwords in plain text. Only the passwords longer than or equal to the minimum length take effect. The minimum length does not take effect for the following passwords:
- Passwords configured during configuration restoration
- Passwords that have taken effect before the minimum length is configured
- This command limits the minimum length of only the passwords in plain text configured using the following commands:
- set authentication password
- lock
- local-user
- super password
The set password min-length command does not limit the minimum length of other types of passwords.
If password complexity check has been disabled using the undo user-password complexity-check command, the set password min-length command does not limit the minimum length of passwords in plain text of local users.
For device security purposes, do not disable the password complexity check function and change the password periodically.
