[BUG] Disconnect-PnPOnline Documentation doesn't match Connect-PnPOnline operation (Ambiguous docco)

[Cadder]

Expected behavior

As documented for Disconnect-PnPOnline docco;
"If instead you simply want to connect to another site collection within the same tenant using the same credentials you used previously, do not use this cmdlet but instead use Connect-PnPOnline -Url https://tenant.sharepoint.com/sites/othersite instead without disconnecting. It will try to reuse the existing authentication method and cached credentials."

Extra Question (for bonus points)

Is there a method of accessing and re-using the Authentication Details with an -interactive MFA connection?
I want to:

• Connect to site A -interactively using the Web/MFA Dialog
• Connect to site B using the same credentials but not having to re-enter them via a second Web/MFA Dialog

Actual behavior

IF you're using the Connect-PnPOnline -Interactive method, you're prompted for credentials again on attempting to connect to second site.

Steps to reproduce behavior

# First connection Displays Web Auth dialog box for MFA Authentication as expected
$ProjectSiteConn = Connect-PnPOnline -URL $ProjectsURL -interactive -ReturnConnection  

# Second connection Displays Windows Authentication Dialog - not as described in Disonnect-PnPOnline docco above
$SharedSiteConn = Connect-PnPOnline -URL $SharedURL -ReturnConnection 

Including -interactive on the second connection string prompts for Web/MFA Authentication again.
(inclusion or omission of -ReturnConnection is irrelevant).

What is the version of the Cmdlet module you are running?

1.11.0

Which operating system/environment are you running PnP PowerShell on?

• Windows
• Linux
• MacOS
• Azure Cloud Shell
• Azure Functions
• Other : please specify

Have you tried connecting to a site, then using Get-PnPAccessToken to fetch the current access token? You could then use that access token to connect again:

Connect-PnPOnline -Url https://contoso.sharepoint.com -AccessToken $token

These tokens do tend to expire after an hour, so it may or may not be suitable for your use case.

...no I haven't. I wasn't aware of that Cmdlet.
..tweaks code..
😲 OMG it worked.
Thankyou @CallumCrowley !
