I do this too. I would need them if I lost my phone, so bitwarden/keepass is a good place for them to be.
I think it is less secure though since someone who somehow has the unencrypted vault without your 2FA device could get in with the codes - but if someone cracks my master password I’m screwed in a whole bunch of ways so I’m not sure it matters too much at that point.
These look cool and would be great images for a Construct Wizard’s familiar or something similar.
I agree with anon that AI images should be accepted here as long as they are clearly labeled and not deceptive. I do downvote slop when it’s just a shitpost but this doesn’t strike me like that.
