When a little knowledge is dangerous!
My employer has just added a benefit of online training for us. When I tried to create an initial password on the (here unnamed) website, it did not let me enter my password of choice. The website requested to have minimum 6 characters, and at least one letter, one number and one special character. A second attempt to add '*' as special character did not work either. So I e-mailed support and asked for the list of the special characters. The answer any of "%$#@&"(and samples that did not quite match the list "some.123" ???)
Well, my back of the envelope calculation tells me with those extra requirements the pasword got less secure:
* 6 characters gives a combination of 76 ^ 6 = 90,458,382,169
* 4 chars + 1 special + 1 number = 76 ^ 4 * 5 * 10 = 20,151,121 * 5 * 10 = 1,007,556,050

90 billion vs 1 billion that is improvement!
