Backend-Owned SMS OTP: Cooldowns and Attempt Caps
This technical blog post explains best practices for implementing passwordless phone logins using SMS OTPs in an Express/Node.js backend. It argues that the backend must own resend cooldowns, verification attempt counters, and anti-abuse policies (not the client), model the authentication state machine (ready → code_sent → verified/expired/locked), persist minimal authoritative state, use atomic database transitions, emit single transition events for observability, and use idempotency keys and retry/backoff handling when calling providers. Provider choices (Twilio, Firebase, Auth0, Amazon SNS, Infrai) are discussed with trade-offs between managed verification and owning template/state-machine responsibilities.
- The article recommends the Express/Node.js backend should own SMS OTP resend cooldowns, maximum verification attempts, and anti-abuse counters rather than trusting the client.
- Designs should expose explicit states: send-code, verify-code, resend-code, and lockout; persist minimal authoritative state (challenge ID, phone identity, expiry, next-send time, counters, lockout).
- Use atomic database transitions and idempotency keys tied to admitted transitions to prevent race conditions and duplicate sends.

Don't Build Login Pages Again: Centralized Auth
The article argues that repeatedly rebuilding login and user/role management across projects is inefficient and error-prone. It describes a common pattern where teams duplicate authentication code across multiple apps, leading to duplicated bugs and maintenance burdens. Two solutions are compared: (1) create a reusable login/user-management module/library to import into projects, and (2) build a separate centralized application (service) that handles authentication, users, roles, and exposes an API for other projects. The author favors the centralized application approach and cites existing services (Auth0, Firebase Authentication, Clerk) as examples, then introduces Roled — a centralized user and role management platform — with links to its site and quickstart documentation.
- Repeatedly copying login and user-management code across projects causes duplicated bugs and maintenance overhead.
- Two approaches are proposed: a reusable module/library, or a separate centralized application for login and user/role management.
- The article cites third-party services such as Auth0, Firebase Authentication, and Clerk as existing options.

European netID Exec Discusses Deterministic IDs and AI's Impact
In an interview, Daniel Dagehus, CTPO of the European netID Foundation, discusses the evolving role of deterministic identifiers in the open web. He argues that while AI and probabilistic models are useful for planning and simulation, deterministic IDs remain essential for campaign activation and delivery to real people across devices. netID has integrated with major ad tech platforms, including The Trade Desk, enabling advertisers to target deterministic segments. Dagehus emphasizes the importance of publisher login relationships to maintain direct user contact and independence from tech providers, especially as AI chatbots change the customer journey. He also highlights FedCM as a standard that can simplify logins and support publisher strategies for direct audience relationships.
- Daniel Dagehus is CTPO of the European netID Foundation.
- netID has integrated with The Trade Desk, allowing booking of netID and Utiq segments in its Data Marketplace.
- netID is a deterministic identifier tied to user accounts and email addresses, providing cross-device identity.

Window for Open-Web ID Push Is Shrinking
Commentary by Klaus Janke (Horizont) warns that the time to deploy deterministic identity solutions in the open web is running out. The article argues that practical adoption of deterministic identifiers such as NetID and Utiq is necessary for the open web to preserve reach and to sustain quality journalism as a pillar of democratic public life. The piece frames the issue as urgent: without widespread implementation of shared identifiers, publishers and the open web risk declining monetization and audience measurement capabilities.
- Opinion piece authored by Klaus Janke published on 2026-08-19.
- The article calls for practical deployment of deterministic identifiers such as NetID and Utiq for the open web.
- The author links adoption of identity solutions to preserving reach for publishers and sustaining quality journalism.
