Cause
This is AOL trying to stop people using its email service to generate spam, you are now required to periodically enter a series of numbers or letters from a web page in addition to normal username and password authentication.
Resolution
See AOL help to understand the issue further. This post on the internet also notes the issue and unfortunately this is something that AOL has added and is not under our control.
