The code was clean, the deploy flawless. Then you saw it: a private key hardcoded into a function no one had touched in months. Silent mistakes like this gut security from the inside. They hide in commits, pull requests, and forgotten scripts. Passwordless authentication breaks that pattern — but only if secrets-in-code scanning is part of your workflow.
Secrets-in-code scanning finds the credentials, tokens, and API keys buried in plain sight. Without it, passwordless authentication is just theory. Real-world breaches often trace back to leaked secrets stored directly in source files. Attackers don’t guess passwords when they can steal your keys from Git history. That’s why modern security teams blend passwordless auth methods with continuous scanning across every repo, branch, and commit.
Passwordless authentication replaces stored passwords with strong cryptographic mechanisms like WebAuthn and public key infrastructure. This eliminates the password database. But if the keys or tokens used to sign, encrypt, or access APIs end up in code, the system is compromised. Secrets-in-code scanning prevents this leak before it reaches production. Integrated into CI/CD, it halts builds when secrets are found, forcing removal or rotation.
