In a few weeks I’ll do a workshop about security for people who are tech illiterate, I plan to teach about password managers and 2FA.
If I show the 2FA number codes, like the 123 456 ones that I have to paste when required, can that be a possible security breach for me? or is it save since is gonna change in a few seconds anyway?

2FA (if it’s true 2 factor), each unique code is also challenged against your password and has a lifespan of all but 30 seconds. Wait a minute before showing the slides, they’ll just be useless numbers by then.
They cannot be reverse engineered in some way as to hack any account. At least not to anyone’s knowledge.
