Prompting to enter MFA every single time

kbyunAncile commented 3 years ago

The Question

I have configured MFA for my named profile. When I use aws cli, it prompts MFA authentication for the first time. Then it caches it for certain duration or when new profile is detected.
But for Powershell aws-tool always prompts MFA authentication every time script runs.

for example, if I have a powershell script

Write-Host "aws cli call"
aws s3 ls
Write-Host "Powershell AWS-Tool Call"
Get-S3Bucket

for first execution, both calls will ask MFA. But on second execution only Powershell AWS-Tool will ask MFA. I wonder if there is a configuration for MFA sessions.

Or maybe it is related to how I'm configuring profile? for AWS CLI, I set environment variable $env:AWS_PROFILE="myprofile" to desired profile for Powershell AWS-Tool, I call Set-AWSCredential -ProfileLocation $env:UserProfile\.aws\config -ProfileName myprofile

Environment

OS Info: Windows 10

Build Version:


AWS Tools for Windows PowerShell
Version 4.0.5.0

Amazon Web Services SDK for .NET Core Runtime Version 3.3.104.35

Hi @kbyunAncile,

Good morning.

AWS Tools for PowerShell rely on AWS .NET SDK behind the scenes. Kindly refer the guidance provided in https://github.com/aws/aws-sdk-net/issues/1844#issuecomment-831580377.

Thanks, Ashish
