Passkey-first authentication. Universal Identity. Private by design.
Private by design
Sensitive data stays encrypted at rest. No readable Personal Identifiable Information (PII) is stored.
Anonymous age verification
User-held encryption keys unlock reusable, one-tap age verification without exposing sensitive data.
Proof of personhood
One-tap, anonymous confirmation that an account belongs to a verified person. Designed for AI platforms working to limit bot accounts and prevent automated model distillation, but useful anywhere an application needs frictionless proof of personhood.
Passkey first
Passwords can be guessed or phished. Email login flows are slow and vulnerable to phishing. Passkeys are fast and phishing-resistant.
FAQ
Some applications need to know that a user is old enough to use their product. Others want confirmation that there is a verified person behind an account. One returns the required identity proof in one tap, helping businesses meet their requirements without collecting personal data or putting users through a long and invasive verification flow.
Users verify their identity once, then reuse it across any application that uses One. No repeated ID uploads, and no new processor to trust with sensitive data. Applications receive only the proof a user approves, not their PII. Their data stays encrypted with a key only they hold, so even a breach of One would not expose readable identity data.
No. Age verification is simply the first privacy challenge that One was built around. The same infrastructure can confirm that an account belongs to a verified person without revealing who they are. At its core, One is a new primitive for persisting sensitive data under user-held encryption. It can power reusable identity presentation for KYC, private AI chat transcripts, and other applications that require persistence of sensitive data without surrendering custody to the platform.
One stores ciphertext: encrypted blobs created with a key held by the user. Never the underlying identity data. This includes government ID and selfie data, as well as the verified email associated with the account.
Only the requested proof and an audit record. For example, that a user is a verified person or is at least 18 years of age, and when the check was completed. No name, birth date, address, selfie, or ID image.
Applications increasingly need to verify aspects of their users’ identities, but traditional verification methods create a new privacy problem. Users upload IDs, selfies, and other PII to providers that can read and retain it, then repeat the process across multiple applications. That creates friction and spreads sensitive data across more databases and attack vectors. One was built around a new primitive to resolve that conflict: reusable identity data encrypted with keys only the user holds. Businesses get the proof they require, while users maintain their privacy and custody of their data.
