A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Hey there, Shady Mohsen Mahmoud
Looking at your last image, you are trying to sign into an admin portal with your personal Microsoft account. You are unable to login to admin portals using your Microsoft account. You have to login to those portals using your work/school account.
If you don't have a work/school account, you should be able to manage Entra ID for Azure through the Microsoft Entra ID blade here: https://portal.azure.com/#view/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/~/Overview
Which looking at your first image, shows the Microsoft Entra ID service in the Azure portal.
Please can you confirm what portal you were trying to sign into?
Can you sign into the Microsoft Entra ID service linked above?
Thanks,
Nathan
