It also have the advantage of not having to save it in a password manager, since I have it on my calender (with a lot of other birthdays saved).
4-digit Birthday-pins are probably good as long as they're not your birthday or that of your kids, and you do the last 2 digits of year, last digit of month, last digit of day, go capture as much of the entropy from the date as possible.
On a side note, I remember back in 2004, a colleague born on Feb 29th, 1984 was unable to enter the U.S. H1B renewal website because someone forgot about leap years in their date validation logic.
Are you saying you can’t have a 4 digit pin? Because if you are then I just want to say that you can have 4 digits if you really want, it just defaults to a 6 digit during setup and there is an option to change to a 4 digit if you want.
Also. Password reuse if a bad thing. If you are really going to reuse a 20 year old pin, you might as well disable pin security completely.
What a foolish statement. Having a pin at all prevents a whole lot of attack vectors, even if weak. Like someone at random picking up the phone and getting personal information off it from any app lacking secondary authentication.
Having a weak pin won’t protect you from someone actively seeking to attack you specifically (a targeted attack). But most crimes are crimes of opportunity, not targeted, and any pin at all reduces the opportunity.
