# First Login

> How to access Keystone after your administrator sends you an invitation.

## Receiving your invitation

Your company administrator creates your account and sends you an invitation email. Click the link in that email to be signed in automatically — no password required.

> If the link has expired or you did not receive an email, ask your administrator to resend the invitation from the People directory.

## Selecting your company

After clicking your invite link, Keystone checks which companies your account is associated with:

* **One company** — you land directly on that company's dashboard.
* **Multiple companies** — you see a company selector listing each workspace you have access to. Click a card to enter it.

## Signing out

Use the sign-out option in the sidebar or application header to end your session. You will be returned to the login page.

## Returning logins

After your first login, return to Keystone at any time by navigating to the login page and entering your email address. A sign-in link will be emailed to you.
