Memory Containers Are a Scope Boundary, Not a Login System
Blog post from Supermemory
Memory containers organize records for retrieval but do not enforce access control, so applications must authenticate users, determine tenant, user, project, and workspace permissions, and construct memory scopes server-side rather than trusting client-provided identifiers. Personal and shared project context require separate authorization checks, and permissions must apply consistently to reads, writes, corrections, exports, deletions, background jobs, caches, generated summaries, and provider API access. The guidance emphasizes unambiguous identifiers, protection against scope collisions and stale cached results, and keeping broad API credentials on trusted infrastructure. Effective integration testing should simulate cross-user and revoked-access scenarios, altered identifiers, and unauthorized deletion attempts while examining retrieved evidence, and managed-memory pilots should use fictional users while retaining authentication and authorization within the application.
