TokenGuard

What it does

TokenGuard is a free, local-first two-factor authentication (2FA) app for iPhone and Apple Watch. TOTP codes are generated on-device, secrets stay in Apple Keychain behind Face ID, with encrypted backups and optional iCloud sync — a private alternative to Google Authenticator, Microsoft Authenticator, and Authy.

TokenGuard generates TOTP verification codes entirely on your device. Shared secrets stay in Apple Keychain behind Face ID — and nothing leaves your phone unless you choose to sync or export. Every feature is built on one principle — your codes belong to you, on your device. Scan an otpauth QR code or enter a Base32 secret manually. Codes are computed locally on the standard countdown — SHA-1, SHA-256 or SHA-512, 6 or 8 digits, custom periods. Shared secrets are stored in Apple Keychain, with account metadata kept in protected app storage under iOS file protection. Unlock with Face ID, Touch ID, or your device passcode. App previews are hidden in the app switcher so codes never show up…from tokenguard.sayai.us

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
