Code #1

Observations

Go through your usual cipher routine, a simple one

Rot 16 gives

kgreifisubstratethtwtwhw

Split into the passcode format

kgr ei fi substrate th tw tw hw

kgr85substrate322hw

Code #2

Observations

15 characters with the right amount of numbers for a valid passcode

Make a 3×5 grid

`v`	`m`	`6`
`6`	`a`	`o`
`m`	`g`	`3`
`o`	`i`	`5`
`3`	`c`	`m`

Reverse rows 2 & 4

`v`	`m`	`6`
`o`	`a`	`6`
`m`	`g`	`3`
`5`	`i`	`o`
`3`	`c`	`m`

Read going down from the upper left V

Code #3

Observations

Those letters fall in a very specific range

Convert letters to numbers

13 13 12 21 11 12 11 11 3 21 3 22 13 12 11 21 12 13 23 12 22 21 11 12 13 22 11 21 1 3 21 22 11 21 22 11 11 22 13 22 12 24 11 22 11 12

No zeros and all in the lower digits. The sum of all digits is 144 which can be divided by 8, RLE is the way to go
