Passwordless authentication promises speed, simplicity, and stronger security. But it also changes the threat model. Secrets detection becomes non‑negotiable. Without passwords, your tokens, magic links, and private keys carry all trust. If an attacker gets one, they own the session.
Secrets in code, logs, or config files are a common failure point. Hidden in a repository, left in a commit, or pushed to a CI/CD pipeline, they are easy for scanners—and attackers—to find. Passwordless systems often rely on asymmetric keys, short‑lived tokens, or certificates. Each must be stored, rotated, and monitored with precision. Hardcoding a key, skipping rotation, or logging a session token is enough to collapse the system.
Effective secrets detection for passwordless authentication means scanning every commit, every build, every deployment. Use tools that parse source code, configs, environment variables, and binary files. Scan for patterns of access tokens, API keys, OAuth credentials, and private keys. Integrate detection into pre‑commit hooks and CI pipelines so secrets never enter your main branch.
