PayPal offers users to store usernames and passwords inside the body.

The innovation engineers at PayPal are confident that the future of authorization is with identification tools that can be embedded in the body, inserted into tissues, or swallowed. The Kill all Passwords presentation demonstrates the unreliability and inconvenience of the existing system (for example, according to their data, 91% of passwords are found in the list of 1000 most popular passwords), and promotes ideas about the future identification.

The concept of logins and passwords has long been criticized by service providers. They are accused of insufficient security services, and they, in turn, accuse users of insufficient caution. Various attempts are being made to replace password-based authorization with other methods - fingerprints and face recognition are no longer exotic.

PayPal especially cares about the safety of users - after all, it’s not just some kind of online service or forum — it’s a money access service. Therefore, the company proposes to move identification forward. Without a special belief in supporting procedures like analyzing a user's habits, his favorite browser and geographical location, engineers suggest moving from external identification (fingerprints, retina, face) to internal - heartbeat, vein drawing, and even identification tags embedded in the body.

Jonathan Leblanc, head of development at PayPal, talks about ideas such as a chip embedded in the skin that tracks the heartbeat and transmits data over a wireless network through an antenna embedded in a tattoo. Or capsules, measuring the level of glucose or other unique parameters of a person that he swallows and uses for identification.

Leblanc makes no promises or predictions about what technologies PayPal will use in the near future. But the company is trying to position itself as a leader in the development of new identification methods and will try to bring something new into this important process.
