The password must be difficult to guess. A good password contains both upper and lower case letters, numbers, and certain allowed special characters. A good password is as long as possible, yet one that you can remember and no one else can guess. It may be difficult to remember a long and seemingly random password, but there are some memory-assisting techniques you can use.
Examples of appropriate passwords
For example, form the password from a sentence that makes sense to you:
- only IPersonally know what Idid last summer,13,no one else!
- This character string seems completely random but it is actually based on an expression you have thought of.
- The opening words from 'A Tale of Two Cities' by Charles Dickens: "[It was the] best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness."
- A rhyme, poem or famous phrase may be easier to remember than a random sentence.
- The displeasing outcome of a trigonometry exam on 27 August at least makes for a good password.
- Even though the idea is quite understandable when written out like this, the phrase doesn't contain any actual words.
- A maximum-length password is usually very strong. You just have to remember it yourself.
The password can even be in plain language and describe, for example, a childhood memory, as long as it is one that no one else can guess and it meets the general criteria.
