Displaying captcha after 3 failed login attempts

[GohanRay]

Is there a way to use devise to keep track of the number of failed
login attempts within a short time period like 15 mins and if it
exceeds 3 attempts, display captcha (ReCaptcha) from the 4th attempt
onwards without locking the account ?

I think you should be able to use the lockable module with
lock_strategy set to :failed_attempts and unlock_strategy set to :none
meaning you'll handle it manually, but instead of trying to lock the
account, just use the failed_attempts field to determine when to show
the captcha.

Thanks.. It works.. We used the automatic locking itself, but set the
maximum number of attempts to 1/0.0 (Infinity)... And then we display
captcha on per-user basis whose failed attempts exceed 3.. The best
part is that the failed attempts for a user is reset to zero once the
user successfully logs in,.. :-) :-)
