Steps
Open a board and click the "Share" button in the top-right
You'll see a list of people with board access
Each person has specific board permissions:
To change permissions, click the permission icons next to a person's name
Toggle View, Edit to allow specific actions
Board permissions can be more restrictive than workspace permissions
Only Editors+ on the board can change their permissions
Notes
Board permissions override broader workspace permissions if more restrictive
You can have board access that's lower than your workspace role
Private boards can be shared with specific people for confidentiality
Regularly audit board permissions to ensure security
