# [Organization] - Invite Users to Organization

This page explains how to invite users to a Contentstack organization (including SSO-enabled organizations) and where to find related API references. It is intended for organization owners/admins who manage user access and roles, and should be used when onboarding new team members or updating organization access.

## Invite Users to Organization

Invite users to your Contentstack organization to enable seamless collaboration across your team.

To invite users to an organization, log in to your [Contentstack account](https://www.contentstack.com/login) and perform the following steps:
- Navigate to your desired organization, click the “App Switcher” icon and select **Administration** from the list.
- Navigate to **Users** and click **Invite User**.
- On the **Invite User** page, enter the email address of the users to invite.**Note**: The selected roles and permissions will apply to all the email IDs mentioned. To add users with different set of permissions, the ideal approach would be to add them separately.
- In the **CMS** section, click **Manage Roles**. This opens a sidebar displaying existing stack-role assignments for the selected users.Select the stacks to which you want to assign roles.
- Choose one or more roles.
- Click **Save** to confirm your selections.**Note:** If no CMS level roles are selected for the user(s), they will not be able to access any of the stacks.
- In the **Administration** section, click **Manage Roles**. The sidebar displays available product roles.Select the appropriate roles for the users.
- Click **Save** to confirm.**Note:** To successfully send the invitation, you must assign at least one role from the Administration section.
- Once done, click **Invite** to send the invitation.

The invited users will receive an email notification. After accepting the invitation, they will be added to the organization with the assigned roles and access.

## Invite Users to SSO-enabled Organizations

For organizations with [Single Sign-On (SSO)](/docs/developers/single-sign-on/about-single-sign-on-sso/) enabled, the invitation process remains the same. However, if “[Strict Mode](/docs/developers/single-sign-on/set-up-sso-in-contentstack#user-management-in-contentstack)” is disabled, you see the **Allow Access without SSO** checkbox. Select this option to let the invited user access the SSO-enabled organization using their Contentstack credentials instead of IdP credentials.
