trying to come up with way(s) to reduce the users' drop off rate on mobile login/registration on a mobile web ecommerce site.
1 method i think could work and would like to probably test would be a web version of the screen unlock pattern feature used on phones. http://ignitersworld.com/lab/patternLock.html
Compared to passwords they are easier to remember and already being used by most users.
Is this a good idea? any limitations or potential problems with this?
How important is security to your system? You'll be effectively trading security strength with ease of use. There are less combinations available for unlock patterns as compared to using a password.
Most e-commerce sites send the user notifications whenever an order is submitted. So if you can make it easy for the user to cancel/stop orders in case of illegal access, it should be fine? I'm not a security expert though.
