Hideez is a digital key for securing users’ devices and data. It requires a smartphone app for a setup, and we build an iOS app and extension for it. The solution offers wide functionality to end users, so making an app for it was both interesting and challenging. Hideez positions as a user’s ‘only digital key’ that can be used for locking/unlocking their devices, storing credentials and keeping them physically separated from other devices, generating one-time passwords for two-factor authentication and more. When the client approached us, they already had a program core and a framework managing the firmware behind Hideez keys. We were asked to create an iOS app for managing the keys and an iOS extension for managing login forms in the browser.
