A cloud-based identity and access management service for securing user authentication and resource access
Hey there, Patrick Roebuck
You can have multiple subscriptions on one account. I have an Azure Student subscription and a pay as you go subscription on the same tenant.
Please can you sign into your tenant here: https://portal.azure.com/#view/Microsoft_Azure_Billing/SubscriptionsBladeV2
Once you have signed into your tenant, please can you click onto 'Add'
You should be able to add the subscription there.
Hope this helps & happy holidays,
Nathan
