Following recent API abuse that lead to phone numbers and usernames being exposed, Snapchat, the social photo sharing app, has updated its iPhone app with the option to opt out of linking your phone number with your username. The feature was intended to increase social discoverability among mutual contacts, but was recently abused leading to the following update and apology:
Find Friends Improvements
This morning we released a Snapchat update for Android and iOS that improves Find Friends functionality and allows Snapchatters to opt-out of linking their phone number with their username. This option is available in Settings > Mobile #.
This update also requires new Snapchatters to verify their phone number before using the Find Friends service.
Our team continues to make improvements to the Snapchat service to prevent future attempts to abuse our API. We are sorry for any problems this issue may have caused you and we really appreciate your patience and support.
The update is available now on for iPhone and iPod touch on the App Store.
