About

Iā€™m an indie developer focused on building lightweight, no-fuss web tools for daily productivity and online work. I created 73hi.com to solve trivial but time-consuming online problems, offering a collection of practical, free, and instant web tools with no download, no registration, and no ads. My mission is to make simple digital tools accessible to everyone, helping individuals, creators, and remote workers streamline daily operations and improve work efficiency. I keep iterating and optimizing 73hi based on real user feedback, focusing on speed, simplicity, and usability. Always building useful tools for the community.

TOTP Authenticator - Local 2FA codes in your browser ā€” nothing ever uploaded

TOTP Authenticator generates verification codes locally in your browser. Add accounts by secret, setup URI or QR code, and get 6-digit codes with a live refresh timer. Accounts stay in memory only ā€” nothing is uploaded, no analytics, no account needed. Save everything into a password-encrypted .73hi.enc backup (AES-256-GCM) you can restore anywhere.
