Plugin to Prevent Brute Force Logins
I'm looking to find a way to prevent people from trying to brute force logins on my forums, I've had a good look around but I couldn't find an existing plugin which offered this functionality which is basically that after X bad login attempts the account is locked for X amount of time.
Does anyone know of such a plugin?
If not, could someone point me in the right direction of how I could hook into the login system to check if the account if blocked or not and when the last unsucessful login attempt was?
I was thinking about storing this in the usersmeta table, does this make sense to you more seasoned developers?
