## What Does Setting Authority Do?

Setting authority changes or revokes specific authority roles on a mint or token
account.

Mint accounts can store a mint authority and a freeze authority. Token accounts
store an owner and can optionally store a close authority. Each role controls a
specific permission set, and setting an authority to _rs`None`_ permanently
removes the selected authority role.

The Token Extension Program also defines additional authority types for specific
extensions.

## How to Set Authority

Changing an authority uses the Token Program's _rs`SetAuthority`_ instruction.

Each call updates one authority type on one mint or token account. The current
authority signs the change, and the new authority may be another address or
_rs`None`_ to revoke the selected authority permanently.
