Wrong account is being connected to when trying to connect to Azure PowerShell (Az Module) account

Question

Hi,

I've previously signed in to Azure on my desktop PC through an account created by my workplace.

However, I've been asked to create an Azure trial account on my own personal email address so I can have a play around with Azure itself (I don't administer our workplace system) to train me up to carry out Azure DevOps certification.

The courses I'm undergoing suggest that as part of the education process for this certification that I install Azure PowerShell.

I have followed the steps outlined in the below guide on how to install; however when I select my personal email address on the Connect-AzAccount part it ends up connecting my work email.

I have tried clearing all browsing history, cookies, cached data and the like but this hasn't fixed the issue either.

Any help on the matter would be greatly appreciated.

Thanks,

Matt
