Human Passport Review 2026: Sybil checks and identity

Human Passport, formerly Gitcoin Passport, is a proof-of-personhood and Sybil-resistance service for web3 applications and communities. It offers wallet scores, verification tools and data services intended to help identify bot or duplicate participation.

The project’s use cases include airdrop and faucet protection, quadratic funding, governance, online communities and gaming. Developers can use its API and Passport Embed tutorial; the homepage also describes a ZK KYC feature for sanction-list verification and wallet recovery using identity-backed cryptography.

Human Passport provides tools that let applications assess whether accounts or wallets are likely to belong to unique people rather than bots or duplicate participants. A wallet can have a Unique Humanity Score, and an application can use its own threshold to inform decisions such as access to a programme or participation in a funding round. A score is an input to an application’s rules, not a guarantee that a person is genuine.

For developers and community operators, the project offers an API and an embed tutorial, along with data services that classify and cluster wallets based on onchain history. Its listed use cases include airdrop and faucet protection, quadratic funding, governance, gaming and spam prevention. The homepage also describes ZK KYC checks for sanction-list verification and identity-backed wallet recovery.

Fees are not published on the homepage. It describes a free API for access to data on more than 2 million Human Passport users, but does not state pricing for other services; integrators should confirm costs with Human Passport before adopting them.

Human Passport handles verification information and offers services based on wallet history, so privacy is an important consideration. The project points users to its privacy practices, but the homepage does not provide detailed information about data retention or access controls.

The homepage does not publish audit details, custody information, or a security incident history. It also does not state a licensing or regulatory status. Scores and identity checks can be inaccurate, so applications should account for false positives and avoid treating a score as conclusive proof of identity.

Human Passport is aimed mainly at developers, community operators and programme organizers who want to reduce bot or Sybil activity in rewards, funding, governance or social applications. Individual users may also use it to check a wallet score, but anyone who shares verification data should first review the project’s privacy practices.
