Connect-AZAccount connects me using the wrong account

[dbutch1976]

Hello,
I haven't worked with PowerShell to manage Azure in a long time, and I see there is a new AZ Powershell Module and that the AzureRM PowerShell module has been officially deprecated by Microsoft.

I am trying to connect to my subscription by using this command:

Connect-AzAccount

This opens a browser which I use to log as normal, but even though I specify privaccount@mycompany.com it eventually logs me in with regularlogin@mycompany.com.

I suspect this is because regularlogin@mycompany.com is the one that I am using for all my other SSO authentication on company websites.

If I am connecting to Azure using the GUI I get around this issue by opening the browser in incognito mode, but I don't know if there is some equivalent I need to do in order to order to make sure I use privaccount@mycompany.com, that's the account that has access to all the subscriptions.

Any ideas?
