Life Insurance Explained

So my aunt passed away a few months ago unfortunately and I was just informed that my brother and I were listed on her life insurance policy. I’ve never been the beneficiary on someone’s life insurance policy and I’m unsure how it all works. Do I get taxed on this money when I receive it? Also I know most life insurance policies at a workplace are 2 times the annual salary so should I expect to get half of that amount or does it not work like that?
