Three codes were found in the Another Way post on the Investigate Ingress blog

[1] 9l7z4abommeqq5d2

[2] 3HMnZyJBLvMCNvJnUPxB

[3] 3b2a5a3b2b1a2a3b2b1a1c3b1b1b1a1a1a3b2c1a3a1b1c1a2b1a2a3a2b5a

Code #1

Observations

4 numbers and the rest letters, looks familiar.

Code #2

Observations

Mix of numbers, small cap and upper cap letters. This looks like a cipher we know.

[hint]Remember that the passcode format changed so it doesn’t need to start with M, N, O or P now[/hint]

Code #3

Observations

Thanks goes out to yushi2000 for submitting the solve to us!

It looks like HEX, but converting it just gives gibberish.
Will need to look further for alternatives.

[hint]

Alternating values reminds you of what kind of code?
How many frequently used versions do we have of such kind of code?
