Hello, this topic is a question, so please use Questions category for such topics.

First of all, passwords are a very sensitive topic, so I hope you know what you are doing.

There can be various solutions, but here is a very simple one + I simplified your code:

#let passwords = ```yaml
--- # User, Password, Shell
-
    - "u1"
    -  "p1"
    -  "/bin/sh"
-
    - "u2"
    -  "p2"
    -  "/bin/sh"
-
    - "u3"
    -  "p3"
    - "/opt/homebrew/bin/bash"
```.text

#let OBF = false
#let OBF = true // Comment this to toggle.
#let HASH = "###########"

#let data = yaml(bytes(passwords))
#if OBF {
  data = data.map(row => {
    row.at(1) = HASH
    row
  })
}
#show table.cell.where(y: 0): strong
#figure(
  table(
    columns: 3,
    align: (x, y) => if y == 0 { center } else { left },
    table.header[User][Password][Shell],
    ..data.flatten(),
  ),
  caption: [passwords.yaml],
) <passwords.yaml>
