Sogdo Auth

Two-step sign-in codes

Your sign-in codes, made on your own device.

Sogdo Auth makes the six-digit codes that protect your accounts. It works on iPhone, Android, Mac and Windows, works offline, and keeps every secret on the device that makes the codes.

Two ways to start

Pick the one that fits you. You can use both in the same app.

Quick local setup

For anyone. Free. No account.

  1. Install the app on your phone or computer.
  2. Scan the QR code a website shows you, or type its setup key.
  3. Use the code the app shows when the website asks for it.

Nothing is sent to us. The app never needs the internet to make a code.

Verified organisation setup

For people whose organisation uses Sogdo Auth.

  1. Your organisation gives you a personal activation code.
  2. Enter it in the app with your work e-mail.
  3. Confirm the one-time code we e-mail to you. Your device is now linked.

Organisation admins manage people and devices at Organisation sign-in.

Privacy, in plain words

  • Codes are made on your device. The secret behind each code is stored only on the phone or computer that makes it.
  • The server never sees a secret. Not in quick local setup, and not in verified organisation setup.
  • Organisation setup only shares what it needs. Your work e-mail, to send you a one-time code, and which device is linked, so your organisation can keep one device per person.
  • No tracking on this site. No cookies, no analytics, no outside fonts or scripts.

For organisations

Give your people verified sign-in codes, see their linked devices and manage activation codes. Admins sign in with their work e-mail and a one-time code; no password to remember.
