OTP වලට Google, Microsoft, .. වගේ කොම්පැනි වලින් ලංකාව බ්ලොක් කරලා තියෙන්නෙ.
Microsoft and Google have restricted the use of One-Time Passwords (OTPs) via SMS or voice calls in certain countries to combat
International Revenue Share Fraud (IRSF). In IRSF schemes, fraudsters exploit telecommunication systems by generating high volumes of calls or messages to premium-rate numbers, profiting from the resulting charges. This activity can lead to significant financial losses for service providers and degrade service quality for users.
Microsoft's Approach:
Microsoft has identified specific country codes where telephony verification is not automatically supported due to elevated fraud risks. For instance, voice verification is restricted in countries like Sri Lanka, Iran, and Venezuela, among others. To enable telephony verification in these regions, administrators must submit a support ticket to opt in. This measure helps protect users and the integrity of Microsoft's authentication systems.

Google's Approach:
Similarly, Google has implemented restrictions on OTP delivery in regions with high incidences of telecommunication fraud. While specific countries are not publicly listed, Google's measures aim to safeguard users from potential fraud and ensure the reliability of their authentication processes.
Alternative Authentication Methods:
To mitigate the impact of these restrictions, both companies encourage users to adopt more secure and reliable authentication methods:
- Authenticator Apps: Applications like Microsoft Authenticator or Google Authenticator generate time-based OTPs directly on the user's device, eliminating reliance on potentially insecure telecommunication channels.
- Hardware Tokens: Physical devices that generate OTPs can serve as an alternative, especially in regions with limited telecommunication infrastructure.
By implementing these measures, Microsoft and Google aim to enhance security and protect users from fraudulent activities associated with telecommunication channels.
