I Built a Zero-Dependency Python Library for OTP Codes

A developer built otp-gateway, a zero-dependency Python library that reads OTP codes from email inboxes via IMAP, eliminating the need for external APIs or services. The library supports generating email aliases and waiting for OTPs, and works with platforms like GitHub, Google, Discord, and OpenAI. It is MIT licensed and available on GitHub.

Every automation project hits the same wall: OTP verification . You're building a bot, a scraper, an automation tool — and then you need to verify an account. GitHub, Google, Discord, OpenAI... they all want a code sent to your email. Your options: otp-gateway https://github.com/fajardev-tech/otp-gateway reads OTP codes directly from your inbox via IMAP. pip install otp-gateway No API keys. No external services. Just IMAP. python from otp gateway import OTPGateway, OTPConfig config = OTPConfig imap email="you@gmail.com", imap password="your-app-password", domain="yourdomain.com", gw = OTPGateway config Generate an alias for the platform alias = gw.generate alias "github" print alias "github-a7k2m3@yourdomain.com" Use this email to sign up, then wait for the OTP result = gw.wait for otp alias, timeout=90 print result "value" "847291" otp-gateway wait user@domain.com In automation, every dependency is a risk: otp-gateway uses only Python's standard library. Copy the otp gateway/ folder into your project and it works. bash Wait for an OTP $ otp-gateway wait github@yourdomain.com ⏳ Waiting for OTP at github@yourdomain.com... ✅ OTP found: 847291 GitHub Check for recent OTPs $ otp-gateway check --email user@domain.com --since 5m Generate an alias $ otp-gateway alias github github-a7k2m3@yourdomain.com GitHub, Google, Discord, OpenAI, Anthropic, DeepSeek, AWS, Azure, Vercel, Netlify, Cloudflare, DigitalOcean, HuggingFace, Stripe, and 15+ more. The pattern library is easily extensible. pip install otp-gateway MIT licensed. PRs welcome. If you build automation tools, give it a try. If you find it useful, a star on GitHub means a lot.
