htpasswd authentication error

[Thu Jul 13 19:26:10 2017] [error] [client 216.158.224.10] user nimda2: authentication failure for "/index.php": Password Mismatch

I've checked and double checked the user name and password. I've even added new ones on the server to make it work. This is really frustrating. None of my websites will work with this software and the setup time for each website is ridiculous. Hand writing each key for each website? hand writing each download id. Searching through the menus looking for where to put those? There's no labeling on what "frontend" and "backend" mean in the context of "manage websites". I had to look up in the manual and even then it's not clear that they mean whether or not both the front end and back end need authentication. What happens when the frontend has a different password from the backend???

I'm sorry, I'm just really frustrated. I've been working with this for days now.

Thanks Jose.
I'm really impressed at how quickly you got on here to address my concerns. Thank you.

Suggestions? I would like to find a faster way to set up all the websites. One way this could be done is to prepare an encrypted file that you can download from your account on the securitycheck website which includes all the set up information for all the websites, including <downloadid> and pregenerated <securitykey>. Make it installable using the Joomla update mechanism. This should be optional.

Another idea is to have all the servers aware of each other (like a cloud environment). When you update the key on one site, you can ask if you want to propagate the information to any other site in that network.

One of the big things in terms of the user experience is having the SecurityCheck server interface be responsive in some way. I'd like to be able to access my information from my cel phone for instance. As it is, I travel with a Surface Pro 4 and I have to scroll left and right to see the information on my screen.

In a related matter, if you have to have an interface that scrolls left and right, it'd be better to put the "checkbox" selectors all on the left side so that you don't have to scroll for each line you want to select. Right now, the alias and the label are on the left side, but the checkbox is all the way on the right. so you have to scroll right, select, scroll down, scroll left, read label, scroll right, select again, scroll left, scroll down, read label, scroll right, select ... etc.

Anyway - thanks for looking into this for me.

Great! Where do I find the modified version?
And, thank you, Jose.
