The password that was sent to me by mail doesent work anymore adn with my 2nd admin account I do not have acces to other accounts to reset the password.
The passwort reset option doesnt sent me an email wit the Reset Code.
I also cannot enter my own CP after 3 wrong password inputs.
Sorry but this is annoying!
1st) What can I do to logon with my admin account &
2nd) What can I do to disabe the site block when the wrong passworrd was entered?
Login with your root user and reset admins password using v-change-user-password
Add your (static) public ip to the fail2ban whitelist (google will guide you how), so it preventing to keeps you banned. I strongly suggest to NOT disable the brute force detection in any case.
I just can not keep myself from quoting what @Raphael wrote, because it is very very important, to NOT disable security options, checks, etc. Quite a few users disable security checks and replace secure passwords with small and insecure ones It is almost certain that trouble will follow.
I am not saying that you did or will do that. Just that other people do it.
