Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Now imagine if you could use FIVE digits for something as important as a bank account.

[–] [email protected] 43 points 6 months ago* (last edited 6 months ago) (4 children)

Even more hilarious is the number of banks that have online login systems that have a maximum length of like 12 characters for the password.

and then the 2nd factor? Yeah that's just another password.

[–] [email protected] 14 points 6 months ago (2 children)

I've met ones that restrict passwords to be 6–8 characters

I use 8! My mom called me ridiculous for doing that :(

[–] [email protected] 49 points 6 months ago (1 children)

It is! How long does it even take to type in 40320 digits?!?

[–] [email protected] 8 points 6 months ago

I figure gotta be, at least 45 seconds!

[–] [email protected] 8 points 6 months ago

She's right, 8 is not a very secure code.

[–] [email protected] 84 points 6 months ago

You can see that 19xx line continue at 20xx too

[–] [email protected] 71 points 6 months ago (1 children)

Now someone tell me which pin is the least common one so we all can use it to be safe.

[–] [email protected] 9 points 6 months ago (2 children)

The ones that are showing black dots.

The fact that every 4-digit pin is in this picture shows quite well how these are pretty easy to crack.

[–] [email protected] 32 points 6 months ago (2 children)

Idk why you would be cracking a PIN code. They aren’t really typically used for online security (and shouldn’t be). And if your attacker is targeting you, the PIN code isn’t meant to stop them.

What it does stop is you finding a random card on the side of the street and finding the nearest ATM to withdraw all of the cash from.

[–] [email protected] 8 points 6 months ago

which will lock the card after 3 tries, so even if you are using your birth year chances are they are not going to guess it

My bank just gave me a random PIN number. Choosing my own was not an option.

[–] [email protected] 15 points 6 months ago (5 children)

I'd forget that so hard.

I used to be able to memorize random sequences of numbers when I was young, but my brain doesn't do that tedious shit any more.

[–] [email protected] 15 points 6 months ago (1 children)

Password manager is the way. It's recommended for all password related things anyway.

[–] [email protected] 17 points 6 months ago* (last edited 6 months ago)

And good ones like bitwarden or keepass, not bad ones that get hacked almost yearly like lastpass

NCC-1701 is the ship designator of the Enterprise from Star Trek

This occurred to me right after I posted. But are there that many ST fans?

It's pretty iconic and when you need to make a 4-digit pin quickly, it's something that stands out if you're a fan of the series. But as the heat map suggests, it may not be the most secure

Looks like there is a bright at 2846, which makes me laugh. My pin is safe, though, at least in this graph, so I guess I'm good.

[–] [email protected] 30 points 6 months ago (1 children)

I imagine many are common based on their geometrical shape on the number pad.

[–] [email protected] 9 points 6 months ago

For my main card it is from the pin I used to reload my Gauntlet save at the arcade, which was based on an easy to memorize joystick pattern used to select the pin on the cabinet

[–] [email protected] 21 points 6 months ago (2 children)

That reddit post is a repost too. Actual source:

[–] [email protected] 50 points 6 months ago (3 children)

There is also the original 'original source'. It includes a version of the picture without the labels and the axis flipped.

[–] [email protected] 14 points 6 months ago

this is so much better. Always read the x axis before the y axis

I wanna know what these black dots are. Forbidden numbers? Numbers the mind cannot guess?

[–] [email protected] 9 points 6 months ago* (last edited 6 months ago) (1 children)

Just the least used. 9805 for example. Mines dark orange and I wasn't even trying, I just made it a physical pattern rather than a number combo.

EDIT: You know, I bet 9805 is gaining popularity in countries that use the Day/:Month/:Year format. Aug 9th 2005 is the birthday of a fair number of adults, now.

[–] [email protected] 7 points 6 months ago (1 children)

There's text over mine, I have no idea how I did. Judging by surrounding stuff, I think I'm ok. The numbers are fairly random.

The bank gave me the code and I just memorized it, and never bothered to change it.

Anyone have a version of this that doesn't have anything overlayed on it?

If the bank is going to make me memorize both a unique 10+ character password and a 4 digit pin, of course I'm going to make a dead easy PIN.

White is most common and dark orange/grey are the least common? By how many standard deviations?

[–] [email protected] 7 points 6 months ago (1 children)

Very valid question, but honestly I hardly think it matters much in this context. It highlights people's patterns, and apparently humans are the worst to ask for random numbers.

On a side note, what's up with the hotspot at 5049?

I spy 2112 in there 🤘🏻

[–] [email protected] 6 points 6 months ago

Set all pins to 6806, got it.

[–] [email protected] 5 points 6 months ago

Here in Australia, post code is also common

[–] [email protected] 5 points 6 months ago* (last edited 6 months ago) (1 children)

There's a noticeable bias to using 10,11, or 12 as either the 1st and 2nd or the 3rd and 4th digits too, especially where the other two digits are lower. Like 11XX, or XX12. Wonder if there's a conscious reason for that or just a notable unconscious human bias for some number combinations?

[–] [email protected] 12 points 6 months ago (4 children)

They are birthdate MM/DD or DD/MM

Where is 4269 in this chart?

[–] [email protected] 13 points 6 months ago (1 children)

Up 42 and to the right 69, duh.

Looks pretty low ranking if I'm seeing the graph right.
