Passkey first
Passwords are legacy, emails are slow. Both are vulnerable to phishing.
One uses passkeys exclusively for instant, secure universal authentication across the internet. Login once, go anywhere.
Login With One
One-tap login, built for the modern age.
Passkey-first authentication. Universal Identity. Private by design.
Ecosystem agnostic
Not tied to any one platform, browser, or device vendor.
One is meant to be a universal identity layer for the web itself, not a captive feature inside existing siloed systems.
Private by design
Client-held encryption keys anonymize user data at rest.
The service can coordinate authentication and proof exchange without becoming a plain text repository of user records.
Proofs, not oversharing
Use verifiable credentials for email, age, and other identity signals.
Apps can ask for the minimum proof they need, and users can share that signal without exposing unnecessary personal data.
Why it matters
Authentication should be invisible. Identity should be explicit.
One separates the act of signing in from the act of disclosing identity. That lets apps move faster, while users keep tighter control over what they reveal.
