Web3 technology holds immense promise — decentralized identity, user-owned data, and frictionless digital ownership. But for this vision to go mainstream, the user experience must be as seamless as what people expect from traditional web2 platforms. While crypto wallets have improved onboarding, the process of logging into apps using those wallets has remained clunky and multi-step.
That’s where WalletConnect Auth comes in.
This new authentication standard is redefining how users sign in to both web2 and web3 applications using their crypto wallets — with just one click. Built on proven principles of decentralization and security, WalletConnect Auth streamlines the login flow while maintaining full non-custodial control over private keys.
What Is WalletConnect Auth?
WalletConnect Auth is a lightweight, secure, and developer-friendly protocol that enables wallet-based authentication across apps and websites. It allows users to verify ownership of their wallet address without compromising security — all through a single tap or click.
Unlike traditional username-and-password logins, WalletConnect Auth leverages blockchain-backed identity. This means no more forgotten passwords, no centralized databases vulnerable to breaches, and no reliance on third-party login providers like Google or Facebook.
Instead, users simply authenticate using their self-custodied wallet — a method that’s not only more secure but also empowers true digital ownership.

Why Simplicity Matters in Web3 Adoption
Despite rapid innovation, web3 still faces a steep adoption curve. One major reason? Complexity.
New users are often overwhelmed by the number of steps required to interact with dApps: installing a wallet, securing seed phrases, bridging funds, connecting via QR codes or deep links — and then still having to sign messages just to log in.
WalletConnect Auth removes one of the most friction-filled steps: multi-stage login flows.
By integrating Sign-in with Ethereum (SIWE) into a single action, it eliminates the need for separate “connect” and “sign” prompts. The entire process happens in one smooth interaction — reducing cognitive load and increasing conversion rates.
This kind of simplicity isn’t just nice to have — it’s essential for bringing the next billion users into web3.
Key Features That Set WalletConnect Auth Apart
1. Ultra-Lightweight SDK for Faster Integration
At just 1/5th the size of WalletConnect Sign, the WalletConnect Auth SDK is optimized for performance and speed. Developers can integrate it in minutes, thanks to its minimal footprint and straightforward API design.
Despite its small size, it supports full end-to-end encryption between the app and wallet, ensuring secure message transmission at every step.
And because it shares core components (like networking and crypto utilities) with other WalletConnect APIs, combining it with existing tools like WalletConnect Sign doesn’t bloat your app.
2. True One-Click Sign-In Experience
Traditional SIWE implementations require two distinct actions:
- First, connect the wallet.
- Then, sign a message to prove ownership.
WalletConnect Auth collapses these into one unified step. When a user clicks “Sign In,” the connection and signature request happen simultaneously — powered by a streamlined cryptographic handshake.
This isn’t just about fewer clicks; it’s about reducing decision fatigue and drop-off during onboarding.
3. Cross-Platform & Universal Compatibility
Whether you're building a web2 SaaS platform or a full-fledged DeFi dApp, WalletConnect Auth works seamlessly across environments.
It supports integration with:
- Web apps (React, Vue, etc.)
- Mobile apps (iOS via Swift, Android via Kotlin)
- Desktop applications
- Embedded experiences (iFrames, widgets)
This universality makes it ideal for developers aiming to bridge web2 audiences into web3 without forcing them to learn new behaviors.
4. End-to-End Encryption & Non-Custodial Security
Security remains foundational. Every authentication request is transmitted over an encrypted channel established directly between the user’s wallet and the application.
No intermediaries. No data harvesting. No private key exposure.
Because WalletConnect Auth operates on a non-custodial model, users retain complete control over their identities — aligning perfectly with the core ethos of decentralization.

Frequently Asked Questions (FAQ)
Q: How does WalletConnect Auth differ from WalletConnect Sign?
A: While WalletConnect Sign is designed for transaction signing and broader dApp interactions, WalletConnect Auth focuses exclusively on authentication. It's smaller, faster, and optimized for one-step login flows.
Q: Can I use WalletConnect Auth for web2 apps?
A: Absolutely. It’s designed to work across both web2 and web3 environments, making it perfect for hybrid platforms introducing blockchain features.
Q: Does it support all wallets?
A: Any wallet supporting WalletConnect v2 and SIWE standards can integrate with WalletConnect Auth. Support is growing rapidly among major wallet providers.
Q: Is user data stored centrally?
A: No. All authentication data is stored locally or on-chain. There is no central database collecting personal information.
Q: Is there a cost to use WalletConnect Auth?
A: The protocol is open-source and free to use. Developers pay nothing to implement or run it in production.
Q: Can I combine it with other WalletConnect APIs?
A: Yes. WalletConnect Auth shares infrastructure with other APIs like Sign and Notify, enabling cohesive experiences without redundancy.
