Install the secure your wordpress site Firewall Plugin. Quit and this plugin investigates net requests with heuristics that are straightforward to recognize attacks that are most obvious.
The stronger approach, and the one I personally recommend, is to use one of the generation and storage plugins available on your browser. I believe after a free trial period, you have to pay for it, although people like RoboForm. I use the free version of Lastpass, and I recommend it for those who use Internet Explorer redirected here or Firefox. That will generate secure passwords for you; then you use one master password to log in.
Yes, you want to do regular backups of your website. I recommend at least a weekly database backup and a monthly "full" backup. More, if at all possible. If you make regular additions and changes definitely. review If you make changes multiple times every day, or have a community of people which are in there all the time, a backup should be a minimum.
Take note of your new password! I recommend the free or paid here are the findings version of the software that is secure *Roboform* to remember your passwords.
I prefer using a WordPress plugin to get the job done. Make sure that the plugin you choose is in a position to do copies that are select, has restore and can clone. Also be sure it is often updated to keep pace. There's absolutely no use in not functioning, and backing your data up to a plugin that's out of date.
