Code #1

Observations

34 letters that seem to be in the range of R to Y. Paired that would be 17 characters which is good for a passcode.

Spoiler

Let’s start by making pairs

sv su ss ux ux rx tq rv rx tq tu rv uu uz uy ru sr

Notice how lots of pairs start with S and look at where numbers should fall, they all start with U. Knowing that in Ascii numbers starts with either 4 or 5, how can we make U=5? Well U is 5 letters before Z.

To make things a bit easier Atbash the string

he hf hh fc fc ic gj ie ic gj gf ie ff fa fb if hi

Convert letters to numbers, a=0

74 75 77 52 52 82 69 84 82 69 65 84 55 50 51 85 78

Convert decimal to Ascii

Code #2

Observations

30 letters, no specific range. Let’s go through the cipher routine.

[hint]Don’t think this cipher has been used since the passcode format change. A might help you :p[/hint]

Spoiler

Atbash, ROT, morse, transposition didn’t give any good results. Next option would be Vigenere but now that the passcode format doesn’t start with numbers it’s a bit harder to brute force. But… there is always Vigenere Autokey with A has the passphrase.

Note that they only way we knew that is that it has been used in the past.

Code #3

Observations

Mix of letters and numbers but that “,” should hint you on what cipher to use

[hint]You’ll need to look at the tool at the tip of your fingers in a different way[/hint]

Spoiler

With that comma it hints to a classic keyboard mirror cipher. We’ve had a few in the past where it was 1=0, q=p, a=; and z=/ but this one is the other way round: 1=z q=a.
