1. Navigate to IAM Dashboard:
   • Sign in to the AWS Management Console.
   • In the top navigation bar, click on “Services” and then select “IAM” under the “Security, Identity, & Compliance” section.
2. Access Account Settings:
   • In the IAM dashboard, on the left-hand side, click on “Account settings.”
3. Set Password Policy:
   • In the “Password policy” section, click on the “Set password policy” button.
   • Configure the password policy settings to enforce complexity. Ensure you enable options such as:
     • Require at least one uppercase letter.
     • Require at least one lowercase letter.
     • Require at least one number.
     • Require at least one non-alphanumeric character (e.g., !, @, #, $).
4. Save Changes:
   • After configuring the desired settings, click on the “Save changes” button to apply the new password policy.

1. Set Minimum Password Length: Ensure that the password policy enforces a minimum length for passwords. This helps in making passwords harder to guess.
   aws iam update-account-password-policy --minimum-password-length 12
   
2. Require at Least One Uppercase Letter: Enforce the inclusion of at least one uppercase letter in the password to increase complexity.
   aws iam update-account-password-policy --require-uppercase-characters
   
3. Require at Least One Lowercase Letter: Enforce the inclusion of at least one lowercase letter in the password to ensure a mix of character cases.
   aws iam update-account-password-policy --require-lowercase-characters
   
4. Require at Least One Number and One Special Character: Ensure that the password includes at least one numeric digit and one special character to further enhance security.
   aws iam update-account-password-policy --require-numbers --require-symbols

AWS (Boto3)

1. Install Boto3: Ensure you have the Boto3 library installed. You can install it using pip if you haven’t already:
   pip install boto3
   
2. Create a Python Script to Set Password Policy: Use the following script to set a complex password policy in AWS IAM:
   import boto3
   
   # Create an IAM client
   iam = boto3.client('iam')
   
   # Define the password policy
   password_policy = {
       'MinimumPasswordLength': 12,
       'RequireSymbols': True,
       'RequireNumbers': True,
       'RequireUppercaseCharacters': True,
       'RequireLowercaseCharacters': True,
       'AllowUsersToChangePassword': True,
       'ExpirePasswords': True,
       'MaxPasswordAge': 90,
       'PasswordReusePrevention': 5
   }
   
   # Set the password policy
   response = iam.update_account_password_policy(**password_policy)
   print("Password policy updated:", response)
   

​

Azure (Azure SDK for Python)

1. Install Azure Identity and Management Libraries: Ensure you have the Azure libraries installed:
   pip install azure-identity azure-mgmt-authorization
   
2. Create a Python Script to Set Password Policy: Use the following script to set a complex password policy in Azure AD:
   from azure.identity import DefaultAzureCredential
   from azure.mgmt.authorization import AuthorizationManagementClient
   
   # Initialize the Azure credentials and client
   credential = DefaultAzureCredential()
   subscription_id = 'your-subscription-id'
   client = AuthorizationManagementClient(credential, subscription_id)
   
   # Define the password policy (Note: Azure AD password policies are managed via Azure AD B2C or Conditional Access Policies)
   # This is a placeholder as Azure AD password policies are not directly managed via the SDK
   password_policy = {
       'minimum_length': 12,
       'require_uppercase': True,
       'require_lowercase': True,
       'require_numbers': True,
       'require_symbols': True,
       'max_age_days': 90,
       'password_reuse_prevention': 5
   }
   
   # Placeholder for setting the password policy
   # Azure AD password policies are typically set via the Azure portal or PowerShell
   print("Password policy should be set via Azure AD B2C or Conditional Access Policies.")
   

​

GCP (Google Cloud Client Library for Python)

1. Install Google Cloud IAM Library: Ensure you have the Google Cloud IAM library installed:
   pip install google-cloud-iam
   
2. Create a Python Script to Set Password Policy: Use the following script to set a complex password policy in GCP IAM:
   from google.cloud import iam_v1
   
   # Initialize the IAM client
   client = iam_v1.IAMClient()
   
   # Define the password policy (Note: GCP IAM does not directly support password policies, typically managed via G Suite)
   password_policy = {
       'minimum_length': 12,
       'require_uppercase': True,
       'require_lowercase': True,
       'require_numbers': True,
       'require_symbols': True,
       'max_age_days': 90,
       'password_reuse_prevention': 5
   }
   
   # Placeholder for setting the password policy
   # GCP IAM password policies are typically managed via G Suite Admin SDK
   print("Password policy should be set via G Suite Admin SDK.")

Summary

• AWS: Use Boto3 to set a complex password policy directly.
• Azure: Use Azure SDK for Python, but note that password policies are typically managed via Azure AD B2C or Conditional Access Policies.
• GCP: Use Google Cloud IAM library, but note that password policies are typically managed via G Suite Admin SDK.
