Web3 Authentication is required whether the user is communicating with the DeFi protocol or wants to get far into the metaverse through the blockchain game. Without the ability to authenticate users on the blockchain, your Web3 applications are bound to fail. However, allowing everyone to participate in the world of Web3 offers life-changing prospects, especially for early adopters.

If you want to be a blockchain developer creating very profitable next-generation dApps, you must be able to implement Web3 authentication. This can be a daunting challenge at first. However, a new paradigm shift called Moralis has arrived.

This industry-leading Web3 development framework, also known as ” Firebase for crypto,” enables frontend developers to quickly establish Web3 authentication in dApps. Thus, they can quickly authenticate users on the blockchain. In this guide, we’ll cover every aspect of Web3 authentication.

What is Web3?

Before diving deeper into Web3 authentication, let’s learn about the most basic concept of Web3. 

The term “Web3” (commonly referred to as Web 3.0) was coined by Gavin Wood, a computer scientist who co-founded Ethereum, Polkadot, and Kusama. Web3 is the next evolution of a decentralized internet where platforms and applications will be built on blockchain and provide enhanced data security, scalability, and privacy for everyone. An important part of Web3 is that users should own and control their online identity and only disclose parts of their identity when they choose to do so.

What is Web3 Authentication?

Web3 authentication sounds complicated, but it is a login mechanism. Also, while Web2 websites use email in combination with passwords, Web3 applications use the user’s crypto address. However, encryption to maintain the security of blockchain networks and their users is much more complicated.

Therefore, manual login will need to deal with public-private key pairs, which is not user-friendly. Fortunately, there are a number of reliable hot crypto wallets available as browser extensions and mobile apps. In addition to storing and managing bitcoins, these wallets can also be used as a Web3 authentication tool.

Why do we need Web3 authentication?

As I said above, Web3 websites and applications run on or at least provide for users to interact with specific blockchains. Therefore, there must be a secure way for users to connect to those particular cryptocurrency networks. By using Web3 authentication, users can connect to a selected network. Once authenticated, they will be given the green light to interact with other authenticated users on that network. As such, every Web3 dApp requires this type of authentication.

However, developers who build directly on Ethereum RPC nodes can tell you how expensive and time-consuming it is to build such authentication from scratch. Fortunately, Moralis allows you to bypass all the limitations of RPC nodes, including authentication. Moralis fully integrates with leading solutions for both web and mobile authentication. As such, you can cover this aspect with a single line of code.

Through Web3 authentication, we can allow users to connect to their desired network. As soon as someone authenticates, they have the ability to interact with other authenticated users on the network. For this reason, it is essential that all Dapps have this functionality to authenticate Web3 users.

Furthermore, as mentioned earlier in the previous section, these authentication mechanisms happen through the Web3 wallet. In contrast, Web2 authentication occurs via email and password, but this makes no sense when it comes to the decentralized web. Therefore, Web3 authentication with a Web3 wallet is essential to keep private key pairs safe and secure. This shows that Web3 user authentication contributes to the security of various blockchains.

Web3 wallet

Web3 wallet is a hot crypto wallet, also known as a digital wallet. They are available as apps and browser add-ons. Moreover, they are an essential tool for everyone who wants to explore the crypto space. A suitable Web3 wallet that allows users to store all types of crypto assets. Furthermore, with cross-chain functionality clearly in the future, most crypto wallets support multiple chains. With Web3 wallet, you can access the DeFi platform, NFT marketplace, blockchain, NFT game, and other crypto platforms. Plus, the Web3 wallet is also a must-have tool for blockchain developers.

Web3 Authentication Alternatives

As I said, the Web3 wallet is used for Web3 authentication, let’s take a closer look at the three most reputable options, which are MetaMask, Wallet Connect, and Web3Auth. Each of these choices offers an excellent user experience. MetaMask and Wallet Connect combined are a perfect experience for native crypto users, while Web3Auth caters to general users. Furthermore, MetaMask is said to be best for web users, while Wallet Connect is a tool that helps mobile users.


MetaMask was brought to life by ConsenSys in 2016, and it has been around the longest. Furthermore, like most of the original engines, it became popular. However, MetaMask did not rest on its laurels. With the continuous development and countless upgrades, it has become a great and extremely powerful tool. It is accessible as a Chrome, Firefox, Brave, and Edge browser extension. Moreover, it also supports iOS and Android devices as mobile applications.

By default, MetaMask covers the Ethereum network, which includes all the most popular Ethereum test nets. However, you can easily add other EVM-compatible networks. Overall, we believe that authenticating with MetaMask is easy and practical; therefore, it is our leading Web3 authentication alternative. In turn, building dApps with MetaMask is a lot simpler. However, be sure to check out how to launch Web3 apps with MetaMask.

Wallet Connect

Many people think of Wallet Connect as an app; however, it is actually an open-source protocol for establishing connections between different wallets and dApps. It is exactly what the name suggests. Therefore, calling it a hot wallet is also technically incorrect. WalletConnect establishes a “symmetric encrypted connection” through a key shared by two peers. Furthermore, this Web3 authentication alternative works with over 75 hot crypto wallets.

To make things user-friendly, WalletConnect allows establishing connections by scanning QR codes or using deep links. As a result, dApps with WalletConnect integration can create a secure and reliable connection easily. WalletConnect is described in more detail if you click the link at the top of this section. Don’t forget to learn how to use Moralis to authorize Android apps.


One of the most well-liked and secure solutions to help new users transition from Web2 to Web3 is Web3Auth. It is used by popular apps like Skyweaver, Binance, and Ubisoft along with many other dApps and wallets. Web3Auth (formerly Torus) is a simple unattended authentication infrastructure that works by aggregating OAuth credentials (Google, Twitter, Discord), different wallets, and the management solution’s existing key. It provides a familiar login experience for every user, thus increasing conversion rates by up to 64%.

You can integrate Web3Auth into your application with a few lines of code. With the mobile and web SDK, you can customize the look and feel of your app and even plug your own existing user/authentication base with the infrastructure.


Magic, formerly known as Fortmatic, is an additional powerful Web3 authentication solution. What’s unique about Fortmatic is that you have complete control over the user experience. It’s embeddable and configurable, so it doesn’t distract people from your app. According to the official Fortmatic website, Fortmatic is an out-of-the-box alternative to MetaMask. As stated before, the focus is on using MetaMask and WalletConnect; Therefore, we entrust it to you for further investigation of Fortmatic.


Here, we have demonstrated how Web3 works as a gateway to the crypto sphere. You know how to give users a way to enter the world of Web3—by implementing an authentication tool like MetaMask. Furthermore, now that you know what Web3 authentication is and how easily you can include Web3 authentication with Moralis, you’re ready to create some awesome dApps.
