I introduced recaptcha to the login screen of a system.
My goal was all about security things like dictionary/bots attacks or other thing of that type.
The users now hate it, Some did not even understand it and I had to remove it.
When I look around, I don't see many systems with that on the login screen, most of the times on other forms like contact us or sometimes like in stack exchange when you want to post.
It made me wonder is it a good idea to have it on the login screen?
