HOW IT WORKS
Verify before you act
When a request feels urgent, unusual or sensitive, SPAFA gives both people a simple way to confirm the relationship before money, credentials or private information are shared.
STEP 02
Compare the code
Both people read the six-digit code shown for the current 30-second window.
STEP 03
Match or stop
Continue when the codes match. Stop and verify through another channel when they do not.
WHEN TO USE SPAFA
A clearer trust check in high-pressure moments
A familiar name, number, voice or face can be copied. SPAFA gives you a separate verification signal before you take an irreversible action.
Suspicious payment requests
Verify a colleague or manager before approving an unexpected transfer.
Family emergencies
Confirm a relative before responding to an urgent request for money.
Sensitive account actions
Verify the person before sharing credentials, codes or private information.
Deepfake and voice-clone calls
Use a direct account-based trust check instead of relying only on a familiar voice or face.
SECURITY BY DESIGN
Built around direct verification
SPAFA does not try to guess whether a voice or video is fake. It gives two authenticated contacts the same short-lived, relationship-specific code to compare during the conversation.
Codes change every 30 seconds
Verification codes are generated on the device
Contacts are accessed only after permission is granted
Raw address-book names and numbers are not stored in contact-discovery records
