# Joining an Existing Organization

To join an existing Arnica organization, you must be invited by an existing organization member. Invitations are sent from **Admin > Security > Users & Roles**.

## Accepting an Invitation

When an organization member invites you, you'll receive a welcome email with a personalized link. Follow the link to set your password and sign in — you'll land directly in the organization you were invited to.

{% hint style="warning" %}
Don't sign in to Arnica before following the invitation link. If you log in first, Arnica will automatically create a new organization for you, and you'll need to delete it before you can join the one you were invited to.
{% endhint %}

## Already in Another Organization?

Each Arnica user can only belong to one organization at a time. If you already have an Arnica account tied to another organization, you'll need to delete that organization before you can accept an invitation to a new one.

## Deleting Your Organization

1. Sign in to Arnica.
2. Click your **account icon** in the upper right corner of the screen.
3. Select **Edit Account**.
4. Under **Danger Zone**, click **Delete Organization**.
5. Confirm the deletion.

You'll be signed out immediately. Your account is now free to join a new organization.

{% hint style="danger" %}
**This action is permanent.** Deleting your organization removes all associated data and cannot be undone.
{% endhint %}

## After Deleting

Once your organization is deleted, wait for your invitation email before signing back in. Use the link in the invitation email to join the new organization. If you sign in without using the invite link, Arnica will create a fresh organization for your account again.

For help sending invitations, see [Users & Roles](/arnica-documentation/platform-operations/security/users-and-roles.md).
