Hi Product Hunt! I built OTPSync because I was tired of constantly reaching for my phone just to copy a 2FA code. I wanted a desktop-first authenticator that makes two-factor authentication faster without sacrificing privacy or security. OTPSync securely stores your TOTP/HOTP accounts, autofills OTP codes directly into supported login forms, imports accounts from Google Authenticator, scans QR codes from your screen, and synchronizes your encrypted vault across devices using OTPSync Cloud, Google Drive, or both. Everything is encrypted locally before it leaves your device, following a zero-knowledge approach, so your secrets remain under your control. This has been a passion project for a long time, and I'm excited to finally share it with the community. I'd love to hear your feedback, ideas, and feature requests to help make OTPSync even better. Thanks for checking it out!
