What is the enrolment process for users that want to prove an attribute or credential?

By putting privacy first and using a novel approach to account protection, Changefly ID offers a path to a safer, more secure, and less-intrusive internet for everyone:
- Changefly ID for anonymous authentication + ANONYMIZED identity & age verification for services that are required to verify minimum age
- Zero-knowledge proofs, secure multi-party computation, temporary unique identifiers
- Protects against bot attacks, bot scraping, identity theft, phishing, credential stuffing, online tracking, and other evolving threats
Changefly ID + Anonymized Identity & Age Verification is like showing a bartender a “Yes, I’m over 21” hologram badge instead of handing them your driver’s license with your name, address, and birthdate. They get what they need—but none of what they shouldn’t have.
We’re just getting started and I’d love to hear what you think, what you’d like to see next, and any feedback you have.
1. User gets their Changefly ID through the Changefly app (free)
2. User verifies their identity anonymously (https://www.changefly.com/account/verify)
For developers:
- Changefly ID is the core technology for anonymous authentication (https://www.changefly.com/our-research). Changefly ID requires zero PII.
- Optionally, if a service requires identity / age verification, we just released Anonymous Identity & Age Verification for Changefly ID (https://www.changefly.com/blog/2025/08/anonymized-identity-a...).
- You can verify your identity for free: https://www.changefly.com/account/verify
- Developers can verify Changefly ID’s and/or age requirement checks with our open API: https://www.changefly.com/developer
