Hi, Currently, you can only change the length of the generated password for VMs by setting the global setting ‘vm.password.length’.
The current password generation algorithm does consider using alpha-numeric characters but no special characters, here it the password generator utility used which can be easily replaced or improved: https://github.com/apache/cloudstack/blob/master/utils/src/main/java/com/cloud/utils/PasswordGenerator.java#L40 For the default length=6, the password would satisfy the regex - [a-z][A-Z][0-9][a-z]* Prior to 4.5, the password server was a socat+bash based program which would save the VM password in /var/cache/cloud/passwords file and I think introducing special characters such as $, %, # etc could have caused some password serving and setup issue. Starting 4.5.1+, the new Python based password server can definitely handle special characters, though we would need to verify is the old reset password scripts would work with password strings with special characters. If you think we should consider improving the generator logic to include special characters etc, you can open a ticket on ACS JIRA.
