This form can have the same meaning as ‘must’, but is generally preferred when speaking about responsibilities. ‘Must’ is generally used to speak about strong personal obligation (For example: I must talk to Peter. It’s important!) Will have to do something is used to speak about future obligations, and had to do something is used to speak about past obligations.
