# Invite an admin

Admins manage the organization: policy, providers, people, billing. They do **not**
need the Endpoint Suite — that's for developers.

## How

1. Go to **Users & Teams → Admins**.
2. Click **Invite Admin**, enter their name and work email.
3. They receive an email with a **passkey setup link**.

The invite appears under **Pending & past invites** with status `pending`. Once they
complete setup it flips to `accepted` and they appear in the admin table above.

## What the new admin does

The link opens a short setup page, then asks them to create a passkey (Touch ID,
Windows Hello, or a security key). There is no password to choose — Sentilai is
passkey-only, so there is no password to phish, reuse or leak.

## Seats

Admins and developers share your plan's seat count. **Users & Teams** shows
`X of Y seats used` under the page title. If you're at the cap the invite is
refused with a "seat cap reached" message — remove someone who has left, or
contact us about a larger band.

## If an invite goes wrong

- **Sent to the wrong address** — click **Revoke** on the pending invite. The link
  stops working immediately.
- **Link expired or lost** — click **Resend**. This issues a fresh link; the old one
  stops working.
- **They lost their device** — see [Resend a passkey link](/books/team-management-and-sso/page/resend-a-passkey-link).
