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.
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.

​
Sign Up

1

Go to zerotwo.ai and click Sign Up

Navigate to zerotwo.ai and click the Sign Up button on the landing page or login screen.
2

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.
3

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.
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.
4

Complete onboarding

After signing in for the first time, you are directed into the onboarding flow. Personal accounts go through the Personal Onboarding flow; Business workspace creation goes through the Business Onboarding flow.
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.

​
Personal Onboarding

All new personal accounts go through a three-step onboarding flow designed to tailor ZeroTwo to your needs.
1

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.
2

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.
3

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.

​
Business Onboarding

If you are creating a Business workspace, the onboarding flow collects information about your organization rather than your personal preferences.
1

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.
2

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.
3

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.
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.

​
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

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.
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.
No. The Free plan requires no payment information. You can upgrade to a paid plan at any time from Settings → Account → Subscription.
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.
