Absolutely, but unless you do stick it to the monitor, you still rely on them remembering where the note is, what it’s for, and keeping it around.
And keeping some passwords in your wallet is only safe for as long as you don’t also include what they are for. Which would be necessary in this case…
I obviously also forbid them from using the same password for everything, which meant that even when they did write their passwords down, finding it was a scavenger hunt that’s an even bigger time-waste than a password reset. Because they never kept them organized or in even in one place!
