The app uses facial-recognition software that verifies the driver’s selfies with the photos stored in the driver’s account. This helps to protect drivers from unauthorized usage of their Flex accounts. In the meantime, a similar policy was implemented by the ride-sharing service, Uber in 2016 requiring drivers to take selfies before signing into the platform and accepting ride requests. “This prevents fraud and protects drivers’ accounts from being compromised. It also protects riders by building another layer of accountability into the app to ensure the right person is behind the wheel,” wrote Joe Sullivan in a blog post in 2016, who was the head of security for Uber back then.
