IAM password policies should require at least one symbol¶
IAM password policies are used to enforce password complexity requirements. Setting a password complexity policy that requires at least one symbol increases account resiliency against brute force login attempts.
Navigate to IAM.
In the left navigation, select Account settings.
Check the Require at least one non-alphanumeric character checkbox.
Click the Apply password policy button.
Set password policy to require at least one symbol.
This operation does not support partial updates. No parameters are required, but if you do not specify a parameter, that parameter’s value reverts to its default value.
aws iam update-account-password-policy <other password options> --require-symbols
