Getting an access token for AzureAD using PowerShell and device login flow

Intro Have you ever wanted to query an API that uses access tokens from Azure Active Directory (AzureAD) from a PowerShell script? There are a lot of solutions for this that uses an application in AzureAD and authenticates using its client-id and secret. If I have a web application or a non-interactive service this is the way to go. My friend and colleague Emanuel Palm wrote a great post on Microsoft Graph API with PowerShell for that scenario.

Validating username and password with PowerShell

The passwords for these accounts are (hopefully) hard to remember and might be shared by a group of people. This means that when it’s time to modify that service , scheduled task or application we haven’t touched in years I really want to make sure I have the right username and password before I start.

Protecting PowerShell secrets with certificate on Yubikey

Intro Sometimes you need to store secrets and PowerShell has a great way of encrypting text for you with the *-CMSMessage cmdlets! Now what if I want other people to be able to encrypt information without being able to decryot it again or if I want to encrypt something myself and only be able to decrypt it by going through a certain procedure like checking out the decryption-key from a secure storage?
