# Signing in

> Create an AcuSight account with Google, GitHub, or email — and how your work email links you to your organization.

Anyone can sign in to AcuSight at [acusight.io](https://acusight.io). You can create an account with **Google**, **GitHub**, or a standard **email and password** — whichever you prefer. There's nothing to configure.

However you sign in, the **email address** on your account is what matters — it decides which organization you belong to.

## Work email vs. personal email

* **Work email** (like `you@yourcompany.com`) — your account is associated with your company's [organization](/guides/administer/orgs-multitenancy). The first person from a company to sign up creates the org and becomes its owner; everyone who signs in afterward with that same email domain joins it.
* **Personal email** (Gmail, Outlook, and similar) — you get your own personal workspace to explore in.

<Note>
  Signing in with Google or GitHub links to your account by email. To join your company's organization, use the sign-in method tied to your **work email address**.
