Difficulty factor determines the time it takes to solve a CAPTCHA. The
|
|
higher the difficulty factor, the longer it will take to generate a
|
|
proof of work for it to solve the CAPTCHA.
|
|
|
|
mCaptcha's proof of work based mechanism makes it highly accessible to
|
|
people with special needs but it is important to choose the difficulty factor
|
|
with care as very high difficulty factors will make the CAPTCHA
|
|
inaccessible to users on slow devices.
