As of iPhone5s we have technology like TouchID which is much secure way of authenticating user instead writing long complicated passwords. Although, we also have a pin login which does require minimal storage inside user brain but it ensures that the authentication must be done with 100% consciousness of the user.
So, I have options to pick and I would like to have pros and cons from community which leads to the best UX.
- Provide TouchID if touch id is enabled and remove Pin Login preference completely (If the system TouchID is ON then remove Pin Login from app).
- Provide TouchID and Pin login as two options and let user pick the best fit for them.
I am also looking for more thoughts on how accessibility related challenges we can face between those options?
