Login Security block my IP address
Even though I uninstalled the module, I kept being banned. To remove the ban for a particular IP, I followed the following steps: 


Connected to the database
Changed the access table; either  changing the status to 1 or deleting the row with  mask equal to '127.0.0.1' and type equal to 'host' works


I found the solution on Sorry, 127.0.0.1 has been banned.
