.DESCRIPTION
Get-GraphTokens is the main user authentication module for GraphRunner. Upon authenticating it will store your tokens in the global $tokens variable as well as the tenant ID in $tenantid. To use them with other GraphRunner modules use the Tokens flag (Example. Invoke-DumpApps -Tokens $tokens)
.PARAMETER UserPasswordAuth
Provide a username and password for authentication instead of using a device code auth.
.PARAMETER Client
Provide a Client to authenticate to. Use Custom to provide your own ClientID.
.PARAMETER ClientID
Provide a ClientID to use with the Custom client option.
.PARAMETER Resource
Provide a resource to authenticate to such as https://graph.microsoft.com/
.PARAMETER Device
Provide a device type to use such as Windows or Android.
.PARAMETER Browser
Provide a Browser to spoof.
.EXAMPLE
C:\PS> Get-GraphTokens
Description
-----------
This command will initiate a device code auth where you can authenticate the terminal from an already authenticated browser session.

.DESCRIPTION
This is a CLI tool for automating the deployment of an app registration to a Microsoft Azure tenant. In the event that the Azure portal is locked down this may provide an additional mechanism for app deployment, provided that user's are allowed to register apps in the tenant.
.PARAMETER AppName
The display name of the App Registration. This is what will be displayed on the consent page.
.PARAMETER ReplyUrl
The reply URL to redirect a user to after app consent. This is where you will want to capture the OAuth code and complete the flow to obtain an access token and refresh token.
.PARAMETER Scope
Delegated Microsoft Graph permissions to scope to the app. Example: Mail.Read, User.ReadBasic.All, etc. Scope items need to be comma separated with each item in double quotes like this (-scope "Mail.Read","openid","email","profile","offline_access")
.PARAMETER Tokens
Provide an already authenticated access token.
.EXAMPLE
C:\PS> Invoke-InjectOAuthApp -AppName "Win Defend for M365" -ReplyUrl "https://windefend.azurewebsites.net" -scope "openid","Mail.Read","email","profile","offline_access"
Description
-----------
This command will inject an app registration with the display name of "Win Defend for M365" with a scope of openid, Mail.Read, email, profile, and offline_access
.EXAMPLE
C:\PS> Invoke-InjectOAuthApp -AppName "Not a Backdoor" -ReplyUrl "http://localhost:10000" -scope "op backdoor" -Tokens $tokens
Description
-----------
This command takes an already authenticated access token gathered from something like a device code login. It uses the hardcoded value of "op backdoor" as the scope to add a large number of permissions to the app registration. None of these permissions require admin consent. Also, by specifying the reply url as running on localhost you can use the Invoke-AutoOAuthFlow module to spin up a web server on the localhost for capturing the auth code during consent flow.
