Sigilo is a privacy-first two-factor authentication (2FA) app. It generates the time-based and counter-based one-time codes (TOTP & HOTP) you need to sign in securely — and it’s built around one simple idea: your data belongs to you. LOCAL-FIRST BY DEFAULT The codes you add live on your device. If you never turn on cloud Sync, nothing ever leaves your iPhone. OPTIONAL CLOUD SYNC Want your codes on more than one device, or a safety net when you switch phones? Turn on Sync and Sigilo backs up your vault so you can restore it whenever you need. Sign in with Apple, Google, or GitHub. Sync is fully optional and always under your control — it only runs when you ask it to. EVERYTHING YOU EXPECT FROM AN AUTHENTICATOR • TOTP & HOTP — works with Google, GitHub, Microsoft, Dropbox, AWS, and any service that supports standard authenticator apps • Add accounts by scanning a QR code, pasting an otpauth link, or entering a key by hand • Organize with folders and find any code instantly with search • Face ID / passcode lock to keep your codes private • Encrypted backup file you can save and restore yourself • Clean, calm “parchment” design that’s a pleasure to use PRIVACY YOU CAN TRUST • No ads, ever • No third-party tracking or analytics SDKs • We never sell your data • Delete your account anytime, right inside the app — it permanently removes your account and any synced data from our servers Sigilo keeps the thing that protects all your other accounts exactly where it should be: with you.
