'Have to' (I/you/we/they) and 'has to' (he/she/it) express external obligation — something required by rules, laws, or circumstances. Negative: don't/doesn't have to means 'not necessary', NOT 'forbidden'. Questions: Do you have to…? It is different from 'must', which expresses personal obligation.
