# Login / Register

Create your Züs account or log in — with Google, your Züs wallet, or MetaMask.

Your Züs account is a **blockchain wallet** — there is **no email/phone sign-up and no one-time passwords (OTP)**. You create or access it with **Google**, your **Züs wallet (Wallet ID)**, or **MetaMask**. The same account works across every Züs app.

### Registration (Account Creation)

#### Step 1: Choose how to create your account

Go to [vult.network](https://vult.network) and click **Sign Up** in the top-right corner.

On the sign-up screen, pick one of three options:

<figure><img src="https://2414485336-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUGN3Vu2Hi1voQQLrIVGO%2Fuploads%2Fgit-blob-0acf8fd5d8914c85bd1ade8dc3226e0bf29a31c3%2Fvult-signup.png?alt=media" alt="Vult sign-up page: Continue with Google, or Private (Continue with Zus / MetaMask)"><figcaption><p>The Vult sign-up page</p></figcaption></figure>

* **Continue with Google** — the quickest option. Züs creates and manages a wallet for you, secured with **split-key** technology, and takes you straight into the app.
* **Continue with Zus** (under **Private**) — create a brand-new Züs wallet directly.
* **MetaMask** (under **Private**) — sign up with your existing MetaMask wallet. If the extension isn't installed, Vult shows an install prompt.

Already have an account? Click **Login** instead — see the [Login Flow](#login-flow).
{% endhint %}

#### Step 2: Save your recovery phrase

If you chose **Continue with Zus** or **MetaMask** and a new wallet is created, Vult shows you a **recovery phrase (mnemonic)** — 24 words that generate your wallet's private key. Write them down, store them safely **offline**, then click **I have saved my key**.

<figure><img src="https://2414485336-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUGN3Vu2Hi1voQQLrIVGO%2Fuploads%2Fgit-blob-c19cc280a306d9e6abdcaf3a10c4897aa947a4f5%2Fvult-mnemonic.png?alt=media" alt="The 24-word recovery phrase with an &#x27;I have saved my key&#x27; button"><figcaption><p>Fig: Signup – recovery-phrase viewer</p></figcaption></figure>

{% hint style="danger" %}
Your recovery phrase is the **only** way to recover your account, and **no one at Züs can recover it for you**. Keep it offline, in physical form if you can, and never share it. Losing it puts your data and earnings on the Züs System in severe danger.
{% endhint %}

#### Step 3: Confirm the phrase (and optionally save your wallet)

Vult then asks you to **confirm a few of those words** to prove you saved them. Optionally name the wallet and set a **password** to save it (encrypted) to the Züs cloud — then you can log in with that password instead of typing the full phrase. Click **Continue**.

That's it — you're registered, and your account works across all Züs apps.

### Login Flow

Log back in with the **same method you signed up with**. As with sign-up, there is no email/phone login and no OTP.

#### Step 1: Choose your method

Go to [vult.network](https://vult.network) and click **Login** in the top-right corner.

<figure><img src="https://2414485336-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUGN3Vu2Hi1voQQLrIVGO%2Fuploads%2Fgit-blob-f9804f6a3ac234a7403ff3a2442cbfbe5aae8f09%2Fvult-login.png?alt=media" alt="Vult login page: Continue with Google, or Private (Continue with Zus / MetaMask)"><figcaption><p>The Vult login page</p></figcaption></figure>

* **Continue with Google** — log in with the Google account you used to sign up.
* **Continue with Zus** (under **Private**) — log in with your **Wallet ID (Client ID)** and passcode.
* **MetaMask** (under **Private**) — connect your MetaMask wallet.

{% hint style="info" %}
New to Züs? Click **Sign Up** to [register](#registration-account-creation).
{% endhint %}

#### Step 2: Wallet ID sign-in (if you chose Continue with Zus)

Enter your **Wallet ID (Client ID)** and your **passcode**, then click **Sign In**.

{% hint style="info" %}
Lost access? On the Wallet ID screen use **Recover with Master Key**, or **Create New Wallet** to start over. Recovery uses your mnemonic / master key — there is no email or OTP reset.
{% endhint %}

That's it! You're now logged in and land on your dashboard.
