# Create an Account

> Sign up for ZeroTwo using email/password or OAuth, and complete the onboarding flow to personalize your workspace.

ZeroTwo supports two sign-up methods: **email and password**, or **OAuth** via Google or GitHub. Both paths give you access to the full platform after completing a short onboarding flow. The onboarding flow differs depending on whether you are creating a personal account or setting up a Business workspace.

<Warning>
  Signing up in an incognito or private browsing window may cause OAuth authentication to fail. Redirect flows and session cookies can be blocked by strict browser privacy settings. Use a standard browser window for the best experience.
</Warning>

## Sign Up

<Steps>
  <Step title="Go to zerotwo.ai and click Sign Up">
    Navigate to [zerotwo.ai](https://zerotwo.ai) and click the **Sign Up** button on the landing page or login screen.
  </Step>

  <Step title="Choose your sign-up method">
    Select one of the three available options:

    * **Email & Password** — enter your email address and choose a strong password
    * **Continue with Google** — authenticate via your Google account
    * **Continue with GitHub** — authenticate via your GitHub account

    OAuth options (Google and GitHub) complete sign-in immediately without a separate password.
  </Step>

  <Step title="If using email: verify your email address">
    After submitting your email and password, ZeroTwo sends a verification email to the address you provided. Open the email and click the confirmation link to activate your account.

    <Note>
      Check your spam or junk folder if the email does not arrive within a few minutes. If it still does not appear, return to the sign-in page and use the **Resend verification email** option.
    </Note>
  </Step>

  <Step title="Complete onboarding">
    After signing in for the first time, you are directed into the onboarding flow. Personal accounts go through the [Personal Onboarding](#personal-onboarding) flow; Business workspace creation goes through the [Business Onboarding](#business-onboarding) flow.
  </Step>
</Steps>

<Info>
  ZeroTwo uses **hCaptcha** on the sign-up form to prevent automated registrations. Complete the CAPTCHA challenge when prompted — it typically takes only a few seconds.
</Info>

## Personal Onboarding

All new personal accounts go through a three-step onboarding flow designed to tailor ZeroTwo to your needs.

<Steps>
  <Step title="Profile">
    Set your **display name**, upload an **avatar** image, and add an optional **bio**. This information appears on your account page and in any shared conversations or canvases you publish.
  </Step>

  <Step title="Interests">
    Select the topics and use cases most relevant to you — for example, coding, writing, research, marketing, or design. ZeroTwo uses these selections to surface relevant model suggestions and feature tips throughout the interface.
  </Step>

  <Step title="Custom Instructions">
    Provide standing instructions that ZeroTwo will include in every conversation. Use this to specify your preferred response format, tone, language, or relevant background about yourself or your work (for example: "I am a backend engineer working in Python and Go. Keep code examples concise and production-ready."). Custom instructions can be updated at any time in **Settings → Personalization**.
  </Step>
</Steps>

## Business Onboarding

If you are creating a Business workspace, the onboarding flow collects information about your organization rather than your personal preferences.

<Steps>
  <Step title="Org Setup">
    Enter your **organization name**, upload a **logo**, select your **industry** from the dropdown, choose your **company size**, and optionally provide your website and a short description. This information appears throughout the shared workspace and in the admin panel at `/admin/general`.
  </Step>

  <Step title="Work Type">
    Choose the primary type of work your team does — for example, software development, marketing, customer support, or research. ZeroTwo uses this selection to pre-configure relevant default tools and connector suggestions for your workspace.
  </Step>

  <Step title="App Selection">
    Pick the third-party apps your team uses most often (for example, GitHub, Notion, Google Drive, Linear, Supabase). ZeroTwo will prompt you to connect these via OAuth immediately so your connectors are ready to use as soon as onboarding is complete.
  </Step>
</Steps>

<Info>
  Business workspaces include per-seat billing managed in the admin panel at `/admin/billing`. Administrators can invite team members, manage roles, and monitor usage from the **Admin** section.
</Info>

## Referral Codes

If you received a referral link, open it in your browser **before** completing sign-up. Referral codes are passed via the `?ref=` or `?referral=` URL parameter:

```
https://zerotwo.ai?ref=YOURCODE
https://zerotwo.ai?referral=YOURCODE
```

The code must be present in the URL at the time you complete registration for the referral to be attributed correctly. Applying a referral code after account creation is not supported.

## Frequently Asked Questions

<Accordion title="Can I change my email address later?">
  Yes. You can update your email address in **Settings → Account**. ZeroTwo will send a verification email to the new address before the change takes effect.
</Accordion>

<Accordion title="Can I link multiple OAuth providers to the same account?">
  Yes. After creating your account, go to **Settings → Security** to link or unlink OAuth providers. You can have both Google and GitHub connected to the same ZeroTwo account, allowing you to sign in with either.
</Accordion>

<Accordion title="What if I lose access to my sign-up email?">
  If you signed up with email/password and can no longer access that email address, contact ZeroTwo support to verify your identity and update your email. If you signed up with an OAuth provider (Google or GitHub), you can still sign in as long as you have access to that provider account.
</Accordion>

<Accordion title="Do I need a credit card to sign up?">
  No. The Free plan requires no payment information. You can upgrade to a paid plan at any time from **Settings → Account → Subscription**.
</Accordion>

<Accordion title="Is incognito mode supported?">
  Basic email/password sign-in works in incognito mode, but OAuth (Google and GitHub) may fail because redirect flows and session cookies can be blocked by strict privacy settings in private browsing. Use a regular browser window if you experience issues.
</Accordion>
