SMS

One-time passcodes, confirmations, and alerts over SMS.

DraftDescribes the intended design. Not yet available — names, fields and behaviour may change.

Syper uses SMS for supported one-time passcodes, transaction confirmations, alerts, and carefully controlled messaging flows.

SMS is not inherently a secure financial command channel. Messages can be intercepted, delayed, or spoofed, and SIM-swap attacks can redirect them. Do not treat an inbound SMS on its own as authorisation to move money.

Supported countries and message types have not been published.
