# Manage user roles
A user must have an **organization role** to participate in a Redox organization. To view or participate in the environments within the organization, a user must have an **environment role** for each one. [Learn more about user roles](/basics/managing-access-for-your-redox-organization/what-are-user-roles).
## Definitions
Organization role
A user’s **organization role** determines their administrative capabilities and access within a Redox organization. There are three types of organization roles:
- owner
- admin
- member
When a user is invited to an organization, they’re assigned to a **member** organization role by default.
A user’s organizational role doesn’t impact their assigned environment role.
Environment role
A user’s **environment role** determines their technical capabilities and access within an environment of a Redox organization. There are three types of environment roles:
- observer (default role in **production** environments)
- support
- engineer (default role in **staging** and **development** environments)
Some of these roles have overlapping permissions and capabilities, but usually for different purposes within the environment. A user’s environment role doesn’t impact their assigned organization role.
## Prerequisites
- A user must be assigned to an **organization owner** role to manage organization roles.
- A user must be assigned to either an **organization owner** or **admin** role to manage environment roles. [Learn more about user roles](/basics/managing-access-for-your-redox-organization/what-are-user-roles).

> Remember that a user can have different role assignments in different environments. For example, a user can be assigned to an engineer role in a development environment but an observer role in a production environment. Or, a user might not be assigned an environment role at all (i.e., they have no access to the environment).
