Flash Calls – Authentication Without SMS Costs
What are Flash Calls?
Flash Calls are a modern alternative to SMS one-time passwords (OTPs). Instead of sending a paid SMS, the system initiates a short, automated call to the user’s phone number. The call disconnects immediately — but the last digits of the calling number are used as the verification code.
This method is fast, secure, and significantly cheaper than traditional SMS authentication.
