Sigilo
Privacy-first two-factor codes — local-first, optional sync.
Sigilo is a privacy-first two-factor authentication (2FA) app that generates the one-time codes (TOTP & HOTP) you need to sign in securely — built around one idea: your data belongs to you. Codes live on your device by default and only leave it when you turn on sync.
A look inside
Everything you expect from an authenticator
Local-first by default
Codes you add stay on your iPhone. If you never turn on sync, nothing ever leaves your device.
Optional cloud sync
Want your codes on more than one device, or a safety net when you switch phones? Turn on Sync — with Apple, Google, or GitHub — always under your control.
TOTP & HOTP
Works with Google, GitHub, Microsoft, Dropbox, AWS, and any service that supports standard authenticator apps.
Three ways to add
Scan a QR code, paste an otpauth link, or enter a key by hand.
Folders & search
Organize with folders and find any code instantly with search.
Face ID & encrypted backup
Face ID / passcode lock keeps your codes private; export an encrypted backup you can restore yourself.
Privacy you can trust
- No ads, ever
- No third-party tracking or analytics SDKs
- We never sell your data
- Delete your account anytime in-app — it permanently removes your account and any synced data from our servers
