The 3 common passcode formats are:

(Stolen with permission from http://niantic.schlarp.com/investigation:apps:ingress:passcodes )

  • Long Passcode1 (Mostly for the retired Niantic Investigation Board) – these have been the most common and follow this format. This format seems to no longer be used.
    [2-9][p-z][a-h][2-9]keyword[p-z][2-9][p-z][2-9][p-z].
  • Long Passcode 2  (Mostly for JOJO Word of the Day WOTD posts) – This was introduced after the powercubes were release and occasionally include them in their rewards. The format is [2-9][p-z][p-z][a-h][2-9]keyword[p-z][2-9][2-9][2-9][p-z] .
  • Long Passcode 3 (Mostly for Niantic Project document posts) – This was introduced on the 17th of January. It is similar to the previous formats , but the letter range is bigger
    [2-9][a-z][a-z][a-z][2-9]keyword[a-z][2-9][a-z][2-9][a-z].

 

Difficulty Rating (out of 8. 1-5 are regular difficulty levels, 6-8 are very challenging):

Source of document:

https://plus.google.com/u/0/+NianticProject/posts/GCBKnKxU9S9

How/where to find the source of the passcode:

Just above the FILE ID, in an image editor, decrease brightness to uncover.

45874857757756284837875835783556

 

Methods/Process:

Passing the string through frequency analysis, there is a disproportionate number of 5’s, 7’s and 8’s.

2(1) #

3(3) ###

4(3) ###

5(8) ########

6(2) ##

7(8) ########

8(7) #######

In decimal representation, numerical characters 0 to 9 are 48 to 57, uppercase characters A to Z are 65 to 90. It is very likely that this string is a decimal representation of the passcode.

Passcode solution:

Breaking the string into pairs will make the solution easier to visualize:

45 87 48 57 75 77 56 28 48 37 87 58 35 78 35 56

Each pair simply needs to be reversed to give a plausible passcode:

54 78 84 75 57 77 65 82 84 73 78 85 53 87 53 65

Converting each decimal number to ASCII:

6NTK9MARTINU5W5A

 

Passcode items gained:

100 AP

100 XM

L3 Resonator (2)

L2 Xp Burster (2)

Portal Shield (2) (Common)
