Modern versions of Windows have many different types of accounts. Local Windows accounts, Microsoft accounts, and domain accounts feature different types of protection. There is also Windows Hello with PIN codes, which are protected differently from everything else. How secure are these types of passwords, and how can you break them? Read along to find out!
