Quoting password requirements here for discussion:
> Your new password must contain 9 numbers, and include at least 4 different numbers but cannot include the same number more than three times.
> To create a new password you will need to confirm some basic personal details (name, date of birth and National Insurance number).
> These must match the details recorded on your Devon Home Choice application.
- danso 9y agoI wish I were clever enough to do a back-of-the-napkin calculation quickly; maybe someone else can do it. What are the number of possibilities given the constraints above, and some reasonable assumptions of human behavior: - At least 2 to 4 numbers will be reference to a specific year, such as the user's birth year or the current year, e.g. 17, 1965, 2017. - As many as 3 to 4 numbers will be a predictable pattern, such as an incremented sequence or repetition of numbers not likely to be a birth year or of `2017`, e.g. `1234`, `987`, `1010`
