Presence Anchors

Presence Anchors are a Phase II feature and are not yet available. This page documents the planned design for SDK B (Presence SDK). Only SDK A (Signal-Only) is currently available.
Presence Anchors will enable platform-scoped presence verification that reduces friction for returning users while maintaining security and privacy.

​
What are Presence Anchors?

Presence Anchors are time-bound, platform-scoped tokens that represent a verified human presence relationship between a user and a specific partner platform. When a user creates an anchor with your platform:
  • A secure, time-bound token is created
  • The anchor is scoped to your platform only (not visible to other partners)
  • Future verifications can use the anchor to reduce friction
  • The anchor expires automatically (default: 30 days)
  • The user can revoke the anchor at any time

​
How Anchors Will Work

  1. Partner requests anchor creation via the SDK B API
  2. User approves in the BotShield app (“Your Platform wants to anchor presence”)
  3. Anchor is created with defined scopes and TTL
  4. Future verifications check the anchor state before requiring biometric
  5. Anchor expires or is revoked, requiring re-anchoring

​
Key Properties

  • Platform-scoped — Each anchor is isolated to a single partner. Your anchors are not visible to other platforms.
  • Time-bound — Anchors expire automatically. No permanent state.
  • User-controlled — Users can view and revoke anchors at any time in the BotShield app.
  • Not identity — An anchor confirms ongoing presence consent, not user identity.

​
Benefits

Reduced Friction

Returning users can verify faster for non-critical actions

Platform-Scoped

Anchors are isolated per partner — no cross-platform visibility

Privacy-Preserving

No tracking or surveillance — anchors are consent-based

Time-Bound

Anchors expire automatically with no permanent state

​
Relationship to SDK A

SDK A (Signal-Only) does not create anchors. Every verification with SDK A requires a fresh biometric check. Anchors are exclusively a Phase II / SDK B feature. If you are integrating today, use SDK A. When SDK B becomes available, you can add anchor support to reduce friction for your most active users.

Coming Soon

Presence Anchors are part of the Phase II roadmap. If you are interested in early access or want to plan your integration ahead of time, contact us.
