Please keep in mind that the tool is no guarantee for a secure password. It does, for example, not check whether your password includes words that occur in dictionaries. Such checks are possible e.g. with the offline version CrypTool 1 (CT1) or with the Password Meter in CTO.

Your password is evaluated only locally within your browser. It will not be sent back to the CTO server.

General recommendations:

Length is more important as the character mix. Minimum length: 12 (recommendations Georgia Tech Research Institute, 2010).

The comprehensive and practical article on How to Set up a Strong Password (July 05, 2017) by James Crace also describes 3 password manager tools.
Tests against most frequently used passwords can be done e.g. with CT1 or with http://comparitech.net/password-strength or with the Password Meter in CTO.
