Check where a message points and how it reached you. ZeroTwo's website is zerotwo.ai, and the official addresses and accounts that its own site and apps link to are listed below. If a message does not match, do not follow it: open ZeroTwo yourself at app.zerotwo.ai or in the app.

## Official addresses

| What | Official address |
| --- | --- |
| ZeroTwo website | zerotwo.ai |
| Web app and sign-in | app.zerotwo.ai (the sign-in page is app.zerotwo.ai/auth/login) |
| Documentation | docs.zerotwo.ai |
| Help Center | help.zerotwo.ai |
| Email | reed@zerotwo.ai, the contact address in ZeroTwo's Terms, Privacy Policy and Refund Policy |
| X | [@zerotwoai_hq](https://x.com/zerotwoai_hq) |
| LinkedIn | [linkedin.com/company/zerotwo-ai](https://www.linkedin.com/company/zerotwo-ai/) |
| Instagram | [@zerotwoai.hq](https://www.instagram.com/zerotwoai.hq) |
| Threads | [@zerotwoai.hq](https://www.threads.com/@zerotwoai.hq) |
| YouTube | [@ZeroTw0Ai-02-02](https://www.youtube.com/@ZeroTw0Ai-02-02) (the handle spells Two with a zero) |
| Discord | [discord.gg/rpM5NaJVva](https://discord.gg/rpM5NaJVva), which the app opens from Help, then Report. The Discord invite in the zerotwo.ai footer has expired; do not rely on it. |

If a message claims to be from ZeroTwo but uses a different domain or handle, treat it as unverified.

## How ZeroTwo reaches you

- **In the app.** The Help menu (the question-mark button next to your name) shows a **What's new** list with a **Full changelog** link, and **Settings**, **Billing** can show a notice such as *Your last payment failed*.
- **By email.** ZeroTwo sends invitation emails, for example an invitation to join a workspace (with a **Join workspace** button) or a friend's invitation with the subject *You're invited to ZeroTwo* (with a **Join ZeroTwo** button that opens zerotwo.ai/auth/signup). Emails built on ZeroTwo's standard email layout end with a footer that links to Help, Privacy and Terms. A footer is easy to copy, so it does not prove a message is genuine on its own.
- **When you sign in.** You get a sign-in link or code when you enter your email address or phone number on the sign-in page, and the page says an emailed link expires after 1 hour.

## What ZeroTwo sign-in looks like

The web sign-in page offers **Continue with Google**, **Continue with Apple**, **Continue with Microsoft**, **Continue with phone** and an email address. It has no password field. Never forward a sign-in link or code to anyone: whoever uses it signs in as you.

## If you are not sure

1. Do not click the link or open the attachment.
2. Go to app.zerotwo.ai or open the app yourself. For a message about payment, check **Settings**, **Billing**.
3. Tell ZeroTwo about the message through **Help**, **Support** or by email, as described in [contacting support](https://help.zerotwo.ai/en/articles/6614161-how-do-i-contact-zerotwo-support).

If you already clicked or shared a code, follow [what to do about suspicious activity](https://help.zerotwo.ai/en/articles/7242626-what-to-do-about-suspicious-activity-on-your-account).
