Entry isn’t Azure. Entra ID is what they renamed Azure Active Directory to. But not always; there’s also Azure Active Directory B2C (yes, that’s the fully expanded name). And various other Azure-branded things that may or may not belong together.

Microsoft are spectacularly bad at naming things.

It’s a miracle they haven’t renamed Windows 11 to “360 365” or “Live 6.5” or “Active-DOS Series X” or something.
