Authy
Authy is an easy to use two-factor authentication service that secures and mananages your online accounts using your smartphone or other devices. The app keeps all your tokens and secures them with a strong authentication.
Because I use this app multiple times daily to login to my various online accounts, I discovered a few friction points that I felt could use some improvements.
Besides the improvements I wanted to make, I decided to ask others what they would like see in their authentication app. I got some feedback from an online poll and on Twitter, and some of the feedback mirrored the initial problems I identified.
I went ahead to create some wireframes and proceeded to design and prototype the app.
I wanted to make sure I didn't just solve my personal pain points with Authy, I also wanted to make sure I got feedback from others, so I asked on Twitter and also got some in-person feedback from other people who used other authentication apps.
Authy was already a great app which I love using, and this was more of a personal exercise to build upon the work of the team, approach the design differently. In this case, the final product was a prototype which was done in Principle.
