The journey to Web3 adoption has long been hindered by one persistent challenge: onboarding. For the average internet user, the process of creating a wallet, securing seed phrases, and understanding blockchain mechanics is intimidating—and often a dealbreaker. Enter zkLogin, Sui’s innovative solution that transforms onboarding from a barrier into a seamless experience.
With zkLogin, users can now access blockchain applications using familiar Web2 credentials—like Google, Facebook, or Twitch—without sacrificing security or privacy. As a native protocol-level primitive, zkLogin eliminates reliance on third-party custodial services or external authentication layers, setting a new standard for user-friendly blockchain access.
This breakthrough isn’t just about convenience; it’s about unlocking mass adoption by meeting users where they already are: in the world of simple logins and trusted identity providers.

The Onboarding Challenge in Web3
Despite the rapid innovation in decentralized applications (dApps), user acquisition remains a major bottleneck. Traditional onboarding requires users to:
- Choose a wallet provider
- Install a browser extension or mobile app
- Generate and securely store a 12- or 24-word recovery phrase
- Fund the wallet with cryptocurrency
Each step introduces friction. Studies show that over 90% of new users abandon dApps before completing their first transaction, largely due to this complexity.
Developers have attempted workarounds, such as custodial wallets or third-party login solutions. But these come with trade-offs:
- Custodial wallets shift responsibility (and liability) to the app developer, increasing regulatory and operational burdens.
- Third-party authentication services introduce external dependencies, often requiring trust in off-chain infrastructure that may not align with decentralization principles.
Until now, no blockchain has offered a native, secure, and private way to authenticate users via Web2 identities—until zkLogin on Sui.
Introducing zkLogin: Secure, Private, and Familiar
zkLogin is a protocol-level primitive built directly into the Sui blockchain. It enables users to log into dApps using existing credentials from trusted Web2 providers—Google, Facebook, and Twitch at launch—with more to follow.
Behind the scenes, zkLogin leverages zero-knowledge cryptography to securely link a user’s Web2 identity to a unique Sui address—without exposing personal data on-chain.
Here’s how it works:
- A user selects “Continue with Google” (or another supported provider) when accessing a zkLogin-enabled app.
- The identity provider authenticates the user as usual.
- zkLogin generates a zero-knowledge proof that cryptographically verifies the user’s identity without revealing any sensitive information.
- A temporary keypair is created, and an ephemeral signature is submitted to the blockchain.
- The user is assigned a unique Sui address tied to that app and identity—automatically managed behind the scenes.
Crucially:
- No private keys to manage
- No seed phrases to remember
- No personal data stored on-chain
Even the Web2 provider doesn’t know the login is being used for blockchain access—preserving user privacy across all parties.
Why zkLogin Changes Everything
zkLogin isn’t just another login button. It’s a foundational shift in how users interact with Web3. Here’s why it matters:
✅ Build for Mass Adoption
Any user with a Google, Facebook, or Twitch account can instantly access Sui dApps. No prior crypto knowledge required. This opens the door to billions of potential new users who’ve never touched a wallet.
✅ Embed Blockchain in Everyday Experiences
Imagine a social media platform that rewards content creators with tokens upon login—or a game that mints achievements as NFTs automatically. With zkLogin, blockchain functionality can be embedded into familiar Web2 experiences without disrupting user flow.
✅ Enable Multi-Device & Biometric Access
Leveraging Sui’s crypto agility, zkLogin supports dynamic key management across devices. Users can switch between phone, tablet, and desktop seamlessly, with biometric authentication (like Face ID or fingerprint) securing transactions—no need to re-authenticate manually.
✅ Strong Privacy by Design
Only two pieces of data go on-chain:
- A zero-knowledge proof verifying identity
- An ephemeral signature for transaction authorization
No usernames, emails, or identifiers are ever exposed. Your blockchain activity stays unlinkable to your real-world identity.

Frequently Asked Questions (FAQ)
Q: Is zkLogin secure compared to traditional wallets?
A: Yes. zkLogin uses zero-knowledge proofs and temporary keypairs to ensure security without requiring users to manage private keys. Since no sensitive data is stored on-chain or by the app, the attack surface is significantly reduced.
Q: Can I still use my existing crypto wallet with zkLogin?
A: Absolutely. Web3-savvy users can continue using their preferred wallets to interact with zkLogin-enabled apps. zkLogin simply adds an additional, more accessible entry point for newcomers.
Q: Does the Web2 provider know I’m using blockchain?
A: No. The authentication flow is designed so that the identity provider (e.g., Google) only sees a standard login request. They have no knowledge that the session is being used for blockchain interactions.
Q: What happens if I lose access to my Web2 account?
A: Since zkLogin ties your Sui address to your Web2 identity, regaining access depends on recovering your Web2 account. This underscores the importance of securing your email and enabling two-factor authentication.
Q: Are there plans to support more identity providers?
A: Yes. While Google, Facebook, and Twitch are supported at launch, Sui plans to expand the list in future updates—including enterprise and decentralized identity options.
Q: Is zkLogin available on Mainnet yet?
A: Developers can start building on Sui Devnet today, with Mainnet rollout expected within weeks. The full SDK and documentation are already available for integration.
