Concerns Rise Over Telegram’s Peer-to-Peer SMS Login Service, Deemed a Privacy Nightmare

Telegram has recently introduced a controversial feature offering users a free premium membership in exchange for allowing the app to utilize their phone numbers as relays for sending one-time SMS passwords to other users attempting to log into the platform. This move has raised concerns regarding potential privacy risks and the exposure of personal information.

The feature, initially identified by the TGInfoEn Telegram channel and reverse engineer AssembleDebug, is currently being rolled out in select countries for Telegram for Android users. By consenting to let Telegram use their phone numbers as OTP relays, users receive a transferable code for Telegram Premium.

However, there are several notable implications and risks associated with this feature. Firstly, users may be subject to a maximum of 150 OTP messages per month, potentially incurring additional charges for local and international SMS usage. Consequently, users may end up paying more through their phone bills than the value of Telegram’s premium membership.

Moreover, there are significant privacy concerns surrounding the exposure of users’ phone numbers to strangers, potentially leading to spam and fraud. While Telegram does provide options for users to hide their phone numbers from strangers, participating in the relay program could compromise their privacy and security.

The terms of service for the peer-to-peer login program indicate that Telegram assumes no liability for any damages or adverse consequences incurred by participants. Users are required to acknowledge and agree that Telegram bears no responsibility for any costs, expenses, or damages resulting from their participation in the program, providing the company with absolute indemnity from related claims.

In summary, while the offer of a free premium membership may be enticing, users should carefully consider the potential privacy risks and implications associated with participating in Telegram’s peer-to-peer login program.
