The iPhone app can set up your one-time codes, and both phone apps turn AutoFill on for you
What’s new
Set Up Codes In. Octa Pass now appears under Settings → General → AutoFill & Passwords → Set Up Codes In on the iPhone. Choose it, and otpauth:// setup links and their QR codes (from Safari or the Camera app) open in Octa Pass, as do Google Authenticator export QR codes. Octa Pass asks before it adds a code, then adds it to the login with the same name or as a new login. See setting up one-time codes.
Turn on AutoFill. The item list shows a Turn on AutoFill prompt until Octa Pass fills for you, and Settings → AutoFill shows whether it’s on. On iOS 18 the system asks right there; on iOS 17 and Android it opens the right settings page. Android 14+ also has a button for Passwords, passkeys & accounts.
Building for your own iPhone.apps/mobile/scripts/ios-device.sh builds a development-signed app and installs it on a connected iPhone. Your Apple team comes from APPLE_DEVELOPMENT_TEAM or a gitignored ios-device.env, and now signs the AutoFill extension too.
