![Best Web3Auth Alternatives [2025]](https://blog-cms.openfort.io/uploads/web3auth_alternative_392a45ad5c.png)
Web3Auth is a popular authentication provider that enables passwordless logins and social authentication for blockchain apps. However, depending on your stack and needs, there are several alternatives that may better suit your project. This article explores some of the top Web3Auth alternatives developers are choosing in 2025.
1. Openfort
Openfort (that's us 👋) is an open-source wallet infrastructure platform designed for applications. Unlike Web3Auth, which focuses primarily on authentication and key management, Openfort offers a complete wallet stack with SDK support. It supports smart accounts (ERC-4337 and EIP-7702), embedded wallets—giving developers full control over the user experience.
Openfort is particularly popular among projects building Web3 applications or game-specific onchain economies. With its ecosystem wallet SDK, Openfort enables teams to create self-custodial flows that are composable and extendable.
Key Features
Compared to Web3Auth, Openfort provides a more comprehensive wallet toolkit for developers. Openfort's main product directions include:
-
Embedded Wallet: Create seamless in-app wallet experiences with support for passkeys, social login, and email authentication.
-
Smart Account Infrastructure: Full support for ERC-4337 and EIP-7702 smart contract accounts with built-in account abstraction.
-
Ecosystem SDK: Build your own wallet toolkit with UI components and communication bridge for cross-app wallet experiences.
-
Multi-Chain Support: Works across all EVM-compatible chains with unified API.
-
Self-Hosting: Open-source under MIT License, allowing you to build and scale web3 apps on your own infrastructure.
How does Openfort compare to Web3Auth?
Given that Openfort is one of the few open-source wallet infrastructure projects with comprehensive smart account support, it offers significantly more flexibility than Web3Auth for teams building custom wallet experiences. Openfort also boasts a larger developer community focused on web3 wallet gaming and wallet consumer app development.

Building In-House Authentication Product
In the realm of web3 authentication, organizations often face the decision of choosing between off-the-shelf solutions like Openfort or Web3Auth and developing an in-house authentication platform tailored to their specific needs. While this option can offer high customization, it comes with its own set of challenges and considerations.
Pros of Building an In-House Authentication Solution
Complete Control: The most significant advantage of an in-house solution is the ability to tailor it precisely to your web3 application needs. This customization can result in an authentication system that aligns perfectly with your existing workflows, brand, and user experience requirements.
No Vendor Lock-in: With an in-house system, you have complete control over your authentication infrastructure without dependency on external providers or their pricing changes.
Custom Features: You can build specific features for your use case, whether it's web3 wallet gaming, web3 wallet DeFi, or web3 wallet AI agents.
Cons of Building an In-House Authentication Solution
Resource-Intensive Development: Developing an authentication solution in-house requires significant time investment in design, development, and testing. This process can divert valuable engineering resources away from your core product development.
Security Expertise Requirement: Building a secure authentication system requires deep cryptographic and blockchain security expertise. This includes not just the initial build but also ongoing threat assessment and response capabilities.
Ongoing Maintenance and Support: Post-deployment, the system will require continuous maintenance to ensure security, performance, and compatibility with evolving blockchain standards. This includes regular updates, patches, and security audits.
Compliance and Audit Challenges: Custom-built authentication systems can face heightened scrutiny from auditors and regulators. Ensuring compliance with evolving regulations can be more challenging compared to using established commercial solutions.
Scalability Concerns: As your application grows, the in-house authentication solution might need significant re-engineering to scale effectively, which can be a resource-intensive process.
Time to Market: Building a production-ready authentication infrastructure can take months or years, potentially delaying your core product launch.
