You can use this FREE service to evaluate the strength of a password - to assess how easily the password can be cracked. You should especially use this service when creating sensitive and critical passwords - for example, FTP, SSH / Telnet, and other server management passwords. And, you should change these passwords on a regular basis - for example, monthly. Ideally, passwords should:
not contain [English Words]
contain at least 3 [Lower-Case Letters]
contain at least 3 [Upper-Case Letters]
contain at least 2 [Numbers]
contain at least 2 [Non-Alphanumerical Characters]
be at least 8 characters in length for [Total Characters]
be sufficiently random - [Binary Signal Entropy] greater than 300
