Passwords are one of several methods by which virus infection can be reduced. A survey in 2012 showed that the four commonest passwords were - password, 123456, 12345678 and abc123.
One of the simplest and most secure passwords can be generated by using the initial letters of a favourite song or phrase. Thus In an English country garden becomes iaecg and, if you need something longer, "Never in the field of human conflict was so much owed by so many to so few" is nitfohcwsmobsmtsf. To make such a password even more secure you could change certain letters to numbers such as "s" to "2", "b" to "6" and "z" to "3". Even GCHQ would take a few weeks to decipher some of these.
Passports not in the drawer I always keep them in. Turning the place upside down.
