Life insurance is used to protect the financial security of the people you love most.
A life insurance policy pays a cash benefit, tax free, to your beneficiaries when you die. The amount of money for which you are insured and the type of insurance you buy depends on your needs.
People can get life insurance through work (some employers offer it through group benefits plans. This type usually ends when you leave the employer.) or they buy it on their own(usually from an insurance advisor).
