ChromePass

You can easily audit the passwords you have saved in your Chrome browser with another great utility from NirSoft. ChromePass is a simple executable that you can download. Simply run it and a table will be generated showing URLs; User Name; Password, and more notably for security purposes a Password strength and for forensics purposes the time at which password were created.

Nirsoft also makes versions of this utility for FireFox, Opera, IE, and one ring to rule them all, WebBrowser PassView.

Facebook Secret Direct Messages

Like Signal and WhatsApp, Facebook direct messages now provide end to end encryption.

When sending a new message look for the secret option in the upper right corner

You can confirm that the messages you are receiving are from a known source by comparing the unique keys for each user's account. In a draft message click on the icon with the person's name. You'll see the option for both your keys and your recipient keys. This will prevent a man in the middle attack.

The messages can be set to auto-destruct. See the ticker icon on the left.

Note that Facebook reserves the right to review messages when one of the participants files a report.

SCOWL

You can use SCOWL,  Spell Checker Oriented Words Lists,  in order to determine the frequency of the spelling of a word, and check whether or not a word is in the open source spell checking program, Aspell, made available by GNU.

If you enter a word on 

http://app.aspell.net/lookup

.. . you'll get search results like this:

Note that an open source word list like this one (which can be downloaded) can be use by hackers in brute force attacks so it may be  a good idea to avoid using words found in it.
