Password Validation
Note Password validation options apply only to user passwords stored in the
CiscoSecure user database. They do not apply to passwords in user records
kept in external user databases nor do they apply to enable or admin passwords
for Cisco IOS network devices.

• Password length between X and Y characters—Enforces that password
lengths be between the values specified in the X and Y boxes, inclusive.
Cisco Secure ACS supports passwords up to 32 characters in length.
• Password may not contain the username—Requires that a user password
does not contain the username anywhere within it.
• Password is different from the previous value—Requires a user’s new
password to be different from the previous password.

both letters and numbers.
