rename your login url to secure your wordpress website will also inform you that there's no htaccess within the directory. You may put a.htaccess record into this directory if you want, and you can use it to handle the wp-admin directory by Ip Address address or address range. Details of how you can do this are plentiful around the net.
The one I personally recommend, and the stronger approach, is to use one of the password generation and storage plugins available for your my blog browser. RoboForm is liked by people, but I think after a free trial period, you have to pay for it. I use the free version of Lastpass, and I recommend it for those of you who use Internet Explorer or Firefox. That will generate passwords for you; then you use one master password to log in.
Keeping your WordPress site up-to-date is one of the most easy things you can do. For the past couple of versions, the ability to install updates has been included by WordPress. Not only that, but websites are notified every time a new update becomes available.
Take note of your password to the next time you sign in! I suggest the paid or free useful source version of the software that is protected *Roboform* to remember your passwords.
However, I recommend that you install the Login LockDown plugin in place of any.htaccess controls. Login requests will stop from being permitted after three unsuccessful login attempts from a certain IP visit this page address for an hour. You can still get into your admin panel whilst away from your workplace, and yet you have good protection against hackers, if you do that.
