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?
For me I’d put proxmox in a proxmox. get the second one installed with a user then save it as a template. From here you can spin up a new image and use the TOTP services to show various 2FA which include YUBI keys if ever the tutorials get deep. I don’t know if there is a 2FA playground as such that just to me seems like a quick low impact way of showing the process. You then just delete that image within the first proxmox install. Hold the phone just searched 2FA playground and it gave me https://pragmarx.com/playground/google2fa#/ which seems perfect for your needs. I can’t vouch for the safety of the site but their github is on there so have a browse through
