Domain settings live in three places, depending on what you're configuring.

## Workspace Domain

Configure under **Settings → General**.

Edit your subdomain name or set a custom domain for your workspace.

### Customize Domain
1. Click **Subdomain** to edit your subdomain (e.g., `yourcompany.twenty.com`)
2. Or click **Custom domain** to set up a custom domain (e.g., `crm.yourcompany.com`)

For custom domains, you'll need to configure DNS settings with your domain provider.

## Approved Domains

Configure under **Settings → Members → Invite**.

Add your company domain to let team members sign up for this workspace automatically.

### Add Approved Access Domain
1. Click **Add Approved Access Domain**
2. Enter your company domain (e.g., `yourcompany.com`)
3. Save

Once configured, anyone with an email address at that domain can join your workspace without needing a direct invitation.

<Note>
This is useful for allowing your entire team to self-register while keeping the workspace restricted to your organization.

## App Custom Domains

Configure under **Settings → Apps → your app → Settings → App URL**.

Apps that expose routes on the web are served from a dedicated URL, shown in the **App URL** section. You can serve an app from a domain you own instead.

### Add Custom Domain
1. Click **Custom Domain**
2. Enter the domain you want to use (e.g., `app.yourcompany.com`)
3. Configure DNS settings as instructed
4. Verify the domain

Only that app's routes are reachable on the domain. SSL certificates are provisioned automatically.
