ID Registry overview — bRRAIn Docs

What the bRRAIn ID Registry is and why every member of the platform should claim their ID.

ID Registry overview

The ID Registry at id.brrain.io is bRRAIn's identity-of-record service. Your bRRAInUserID is a stable, optionally-public identifier that you can attach to your work to prove authorship, surface credentials, and make your identity portable.

What an ID is

A bRRAInUserID is:

  • Globally unique within bRRAIn.
  • Stable — it doesn't change when you change jobs, organizations, or email.
  • Optionally public — you control what's visible.
  • Cryptographically verifiable — claims attached to it (certifications, attestations) are signed.
  • Portable — usable on resumes, contracts, code commits, design files, anywhere you want provable identity.

Two forms of the same ID:

  • Canonical — BBI-AB12-CD34-EF56-7890. Always works.
  • Vanity — your-handle. Shorter, claimed first-come-first-served.

What you can do with it

Claim a vanity handle

Reserve id.brrain.io/u/your-handle as your public identity URL. It can host a one-page bio site (see Vanity URLs) or just redirect to your profile.

Display your certifications

Any bRRAIn-issued certification (from learn.brrain.io) automatically appears on your profile with a verification link. Recipients can verify any certification independently.

Issue verification chips

A chip is a short-lived, signed token you embed in any artifact (resume, contract, design file, code commit). Recipients verify the chip to confirm the artifact came from you and bears your verified credentials.

See Verification chip.

Sign your work

Records you author in your organization's bRRAIn carry your bRRAInUserID as a stable signature. Even if you leave the organization, your authorship is preserved.

Move identity across organizations

Your ID is yours, not your employer's. When you switch jobs, your ID and your earned credentials follow you.

Privacy controls

You control what's visible:

  • Display name — defaults to your account name; can be a pseudonym.
  • Bio — short prose; visible on your profile.
  • Avatar — optional.
  • Links — your other web identities; optional.
  • Certifications — show all, show some, or show none.
  • Organizations — list your memberships, list with role, or hide entirely.
  • Verification chip log — show artifacts you've signed, or keep private.

Each visibility setting is independent. You can have a fully public profile with private chip history, for example.

Authentication and signing

Behind the scenes, your ID has a key pair. The private key stays in your account's secure store; the public key is published.

When you issue a chip or sign a record, your private key produces a signature that anyone with the public key can verify. We never expose your private key.

ID handling rules

  • Reservation — once claimed, a handle is yours until you release it (or until 12 months of inactivity, after which it becomes available again).
  • Reserved names — some handles are reserved (system terms, common offensive language, names of well-known people). These are not claimable.
  • Disputes — if you believe someone has claimed a handle they shouldn't have (impersonation, trademark infringement), report it. We follow standard takedown procedures.

Free vs Pro

The base ID is free. Some features are part of the bRRAInUserID Pro annual subscription:

  • Custom one-page vanity site builder.
  • Verification chip styling and unlimited chip issuance.
  • Custom domain on your vanity URL (brand.example.com instead of id.brrain.io/u/handle).
  • Profile analytics.
