If you want to invite a designer to your account without allowing them to edit boards, what should you do?

Inviting a designer as a viewer (read-only) is the best option when you want to allow them access to view boards but not grant them editing permissions. This role provides a way for team members to see the project's details, updates, and progress without the ability to make changes or alter any data.

This is particularly useful in scenarios where you want to maintain control over the project while still keeping team members informed. By using the viewer role, the designer can contribute their insights without the risk of them modifying critical elements of the project.

The other options involve granting more access than intended, whether it’s complete editing privileges, direct sharing with potential security concerns, or using settings meant for editing that can inadvertently allow changes. Thus, inviting the designer as a viewer is the most secure and appropriate choice for your needs.
