Use the API Gateway to get MFA code

• Install terraform
• Install AWS CLI
• Set AWS credential in your environment, aws configure --profile your_profile_name

Modify terraform.tfvars.template to terraform.tfvars, and set the tfvars

• aws_profile = "your aws profile"
• aws_region = "your aws default region"
• resource_tags.project = "your project name"

• Deploy resources:

  terraform init

  terraform plan

  terraform apply

• Delete resources:

  terraform destroy

• API Gateway
• Lambda Function
• IAM Role
• IAM Policy
• Cloudwatch Log Group

• After deploy, get output api_gateway_url

• Add /?token=xxxxxxxxxx behind api gateway url

• Ex: https://xxxxxxxxxx.execute-api.us-east-1.amazonaws.com/?token=xxxxxxxxxx

• Change your token which you want to get the MFA code

• Type the URL in your browser, you will get the response {"mfa_code": "237533", "countdown": 26}

• Congratulations, you can get the MFA code now
