PRESENCE BY 4SI
Authority begins
with presence.
Presence is the private control environment for physical trust. Access is limited to invited accounts and verified with a device-bound passkey.
Phishing-resistantNo reusable password is transmittedInvite-onlyEvery account is issued by an authorized administrator
SECURE ACCESS
Sign in with your passkey
Your device will ask for Face ID, Touch ID, Windows Hello or its local unlock method. 4SI never receives that biometric data.
FIRST-TIME ACCESS
Authentication is challenge-bound, origin-bound and verified server-side. Sessions expire automatically.A passkey is created only after a one-time invitation has activated the account. Do not use the sign-in button before that step.
