# Authentication

> How signing in to Antlect works.

Antlect uses secure single sign-on for all access. There are no passwords stored by Antlect itself.

## Signing in

1. Click **Login** on the Antlect landing page.
2. You're redirected to the secure login screen to authenticate.
3. On success you're returned to your workspace, signed in.

Sessions are token-based and expire automatically; you'll simply be asked to sign in again.

## Accounts and roles

Every account has a role:

| Role  | Capabilities                                                                                                            |
| ----- | ----------------------------------------------------------------------------------------------------------------------- |
| User  | Full platform access: projects, queries, reports, library                                                               |
| Admin | Everything a user can do, plus the [admin dashboard](/admin/admin-dashboard): access-request review and user management |

## Signing out

Sign out from the account menu in the sidebar. This ends your session everywhere the token is used.
