If you start reading at the lower right M and the middle column you can make out the word Myosoti and adding the upper right S gives Myosotis. To get valid prefix and suffix you need to reverse rows 2, 4 & 6

Observations
All numbers but part of the range doesn’t look good for Ascii

Let’s start by making pairs to see if we can spot a pattern
86 74 75 50 51 03 12 42 90 96 55 50 52 79 66
Looks like we have a good prefix and suffix, let’s change those from decimal to Ascii

The middle part has 10 numbers, could be ISBN-10 book codes. Searching on Google gives a book called Gain

Observations
Right amount of numbers for a valid passcode
Spoiler
Making rectangle didn’t give anything that looked like a passcode. Let’s try to find the keyword first. Since we have 15 characters we know the keyword is 5 letters. You can use this site to make a regex search to find the keyword. Check the help section, the string you need to input for the search is ^[4vj87c92evvrade]{5}$
The only result that is shown is Devra.
Going back to rectanlges, make a 5×3 grid

In the bottom row you have all the letters needed to spell devra. Reorder the columns as 4, 5, 1, 2, & 3
