About the password generator.
The password generator, that generated the passwords above, is a piece of PHP programming code, that I wrote. It loads a set of special characters, a set of numbers, a set of lower case letters and a set of upper case of letters, which it uses to create a pool of characters, that can be used one or more times to create passwords.
The pool of characters does not contain special characters, that could conflict with HTML. An example is generation of entity numbers and entity names. It then uses a random number generator to pick characters from the pool and generate passwords to the given length.
Each password, that is generated above, has been generated on the fly and printed directly to this page. None of the passwords have been through a database, have been written to temporary storage or logged in this process.
