# Requirements for Using Inheribase

> Review the browser, device, and account prerequisites before creating your Inheribase vault. Most users are ready to start in under two minutes.

Before creating your vault, review the prerequisites below. Inheribase is designed to work with minimal setup — the mandatory requirements cover what every user needs, while the optional requirements unlock advanced capabilities for high-value estates or AI-assisted management.

## Mandatory requirements

### Supported browser

Inheribase requires a modern browser with **WebAuthn (passkey) support**. The following browsers are fully tested and supported:

| Browser           | Minimum version | Passkey support |
| ----------------- | --------------- | --------------- |
| **Chrome / Edge** | 109+            | Full            |
| **Safari**        | 16.1+           | Full            |
| **Firefox**       | 122+            | Full            |
| **Brave**         | 1.52+           | Full            |

**Mobile browsers**: Safari on iOS 16+ and Chrome on Android 9+ are fully supported. Older mobile browsers may lack passkey capabilities.

### Email address

A valid email address is required for:

* Account creation and identity verification
* Guardian and heir invitation delivery
* Dead Man's Switch check-in notifications
* Release sequence alerts

### Device with biometric or PIN

Passkey authentication requires a device that supports at least one of the following unlock methods:

* **Biometric** — Face ID, Touch ID, or fingerprint sensor
* **PIN / Password** — Your device unlock credential
* **Hardware security key** — YubiKey, Google Titan, or any FIDO2-compatible device

## Optional requirements

### Hardware security key

For users with high-value estates, a FIDO2-compatible hardware key provides an additional authentication factor and reduces reliance on device biometrics:

* YubiKey 5 series (USB-A, USB-C, NFC)
* Google Titan Security Key
* Any FIDO2/WebAuthn-compatible device

### Cryptocurrency wallet

A crypto wallet is only required if you plan to interact with Inheribase's on-chain identity layer directly:

* MetaMask, Coinbase Wallet, or any WalletConnect-compatible wallet
* Connected to **Base Mainnet** (Ethereum L2)
* A small amount of ETH on Base for gas (identity mint only)

<Note>
  Most users do not need a crypto wallet. Inheribase automatically provisions an embedded smart account wallet during signup using your passkey. An external wallet is only needed for advanced on-chain operations.
</Note>

### AI assistant (MCP)

To use AI-assisted estate management through the Inheribase MCP server, you need:

* **Claude Desktop**, **Cursor**, or any MCP-compatible AI assistant
* An Inheribase API key (generated from your dashboard)
* Node.js 18+ (for the MCP server package)

See the [MCP Server Guide](/agents/mcp-server) for full setup instructions.

## Supported file types

Inheribase accepts **all file types** without restriction. Encryption operates on raw bytes, so the format does not matter. Common categories include:

| Category        | Formats                                                            |
| --------------- | ------------------------------------------------------------------ |
| **Documents**   | PDF, DOCX, TXT, RTF, ODT, XLSX, CSV                                |
| **Images**      | JPG, PNG, HEIC, TIFF, SVG, WebP                                    |
| **Video**       | MP4, MOV, AVI, MKV, WebM                                           |
| **Audio**       | MP3, WAV, FLAC, AAC, OGG                                           |
| **Archives**    | ZIP, TAR, 7Z, RAR                                                  |
| **Credentials** | JSON, TXT, KEY, PEM (encrypted locally before upload)              |
| **Other**       | Any file type — Inheribase encrypts raw bytes regardless of format |

### File size limits

| Limit                | Value                                                 |
| -------------------- | ----------------------------------------------------- |
| Per-file maximum     | 5 GB                                                  |
| Total vault capacity | Unlimited (determined by Vault Credits balance)       |
| Upload method        | Chunked upload with resume capability for large files |

## Network requirements

* **Bandwidth**: Minimum 1 Mbps for uploads; faster connections are recommended for large files
* **Connectivity**: A stable internet connection is required during upload and download operations
* **Offline access**: Not currently supported — vault access requires an active connection

## What you do NOT need

<Note>
  **The Simplicity Standard**: If you can send an email and upload a file, you can use Inheribase. All cryptographic complexity is handled entirely behind the scenes.

  You do not need:

  * Cryptocurrency knowledge or blockchain experience
  * Software installation (Inheribase is a web application)
  * A monthly subscription or credit card on file
  * Technical expertise beyond basic web browsing
