How to log in to Azure Portal using a Temporary Access Pass?
Steps to log in to the Azure Portal using a Temporary Access Pass.
Click on the Azure Portal link as shown below:

You’ll see the Sign in to Microsoft Azure window. Enter the Username, which can be found under the Environment Details tab.

Next, provide your Temporary Access Pass.
Note: If you're asked to enter a Temporary Access Pass instead of a Password when signing in to the Azure portal, don't worry, it refers to the same credential. You can find it under the Environment Details tab.

If you see the pop-up Action Required, click Ask Later.
If prompted to stay signed in, you can click No.

If a Welcome to Microsoft Azure pop-up window appears, simply click "Maybe Later" to skip the tour.
