Instant breach lookup

Check passwords or hashes securely against 26+ billion leaked credentials without leaving your terminal.

Cross-platform binaries

Ship-ready builds for Windows, Linux, and macOS (Intel and Apple Silicon) with zero external dependencies.

Automation friendly

Perfect for CI/CD, DevOps scripts, or local audits thanks to JSON responses and simple command flags.

Privacy-first security

All lookups are hashed, HTTPS-secured, and never expose the raw password outside your environment.

Key Benefits

Lightweight binaries, strong privacy guarantees, and automation-ready workflows for any security team.

  • Instant breach lookup — hashed & HTTPS-secured queries backed by 26+ billion credentials.
  • Cross-platform support with single static binaries for every major OS.
  • Privacy-first design that keeps secrets local while authenticating via x-api-key.
  • Quota awareness with built-in rate-limit status checks.
  • Automation ready — perfect companion for CI/CD pipelines and password audit scripts.

Main Commands

Use -a or --api-key to authenticate. Responses are JSON, ideal for piping into tools like jq.

Breach Check

Perform a live breach lookup using your API key.

Password
loginguards check -a "<api-key>" -password "<password>"
SHA1 hash
loginguards check -a "<api-key>" -sha1_hex "<hash>"
SHA512 (30-char prefix)
loginguards check -a "<api-key>" -sha512_30 "<hash>"

View API Logs

Display your recent API usage including timestamps, endpoints, and status codes.

Logs
loginguards logs -a "<api-key>"

Account Insights

Inspect your active plan, quotas, and linked account profile.

Plan
loginguards plan -a "<api-key>"
Profile
loginguards profile -a "<api-key>"

Usage Notes

Every request is sent to https://api.loginguards.com/v1 with secure headers and hashing.

  • Authenticate with -a or --api-key. The CLI sets the x-api-key header automatically.
  • All requests are HTTPS + hashed — plain passwords never leave your machine.
  • JSON responses make it simple to parse results in shell scripts and automation.
  • Ideal for CI/CD workflows, DevOps scripts, or local password audit tooling.

Example

Single command breach lookup and sample JSON response.

Command
loginguards check -a "lg_f7QP0dJ8rMx1Vs3G4kWnZy6Bt" -password "P@ssw0rd!"
Output
{
  "found": true,
  "sources": 28,
  "last_seen": "2025-09-03T22:10:00Z"
}
