# Introduction

## Overview

Identify Snap extends MetaMask's features by adding support for Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs), thereby turning MetaMask into a DID wallet.

Identify Snap supports 3 did methods - did:pkh, did:key and did:hedera and users can choose between the 3 methods. More methods will be supported in the future.

Examples of use cases for Identify Snap include:

1. Secure access control: Identify Snap can be employed for authentication and authorization purposes, granting users secure access to various online services and resources based on their verifiable credentials.
2. Credential management: Users can create, manage, and verify their credentials, such as educational qualifications or professional certifications, with the added convenience and security provided by the MetaMask extension.
3. Decentralized identity management: Identify Snap empowers users to establish and maintain control over their digital identities through the use of DIDs and VCs, thus ensuring privacy, security, and reduced reliance on centralized authorities.

In summary, Identify Snap is a valuable addition to the MetaMask ecosystem, offering users an array of enhanced features and enabling developers to incorporate advanced identity management functionalities into their applications.

## What is a Snap?

Metamask Snaps is an open source system that allows anyone to safely extend the functioanlity of Metamask, creating new web3 end user experiences. A Snap can add new API methods to MetaMask, add support for different blockchain protocols, or modify existing functionalities using the [Snaps JSON-RPC API](https://docs.metamask.io/snaps/reference/rpc-api/).

Snaps enable users to interact with new blockchains, protocols, and decentralized applications (dApps) beyond what is natively supported by MetaMask. The goal of the MetaMask Snaps system is to create a more open, customizable, and extensible wallet experience for users, while fostering innovation and collaboration within the blockchain and decentralized application ecosystem.

Developers can write MetaMask Snaps using JavaScript, making it accessible and convenient for a broad range of developers to create custom solutions. Users can then opt to install these snaps to enhance their MetaMask experience, provided they trust the source of the snap.

## &#x20;What are some of the Identify Snap features?

* Get the Decentralized Identifier(DID) associated with the currently connected metamask account or a non-metamask account(i.e. imported via private key)
* Supports 3 did methods - did:pkh, did:key and did:hedera
* Control non-EVM accounts(eg. Hedera Accounts that deal with Account Ids) and assets in MetaMask
* Store and manage Verifiable Credentials(VC) data on your device and remotely(eg. storing VCs on personal google drive to allow sync feature)
* Generate Verifiable Presentation(VP) from one or more VCs
* Verify VCs and VPs

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tuum.tech/identify/basics/introduction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
