SN1024 Deblur of images real & why nobody offers passkeys as second factor

[dusanmal]

From my work in astrophysics, with Hubble telescope, it is possible to "deblur" images to incredible level if some conditions are satisfied. One must know detailed optical properties of the camera, both lenses and sensors. Also, multiple images must be taken, trivial if it is a video. Not even an AI, regular Math and computing. We did it with Hubble to find precise stellar motions in satellite galaxies of Milky Way. To the precision of 1/100th of the Hubble sensor pixel size.
Recent pet-peeve with all passkeys hype: why is nobody allowing for a choice of passkeys as a second authentication factor? Attack surfaces and benefits are so different that the "something you KNOW" PLUS passkey is definitely the safest option however, even Steve wants to eliminate passwords and their unique value for those who know how to properly use them.

were lasers involved?

In that case you're finding the information that is obscured by noise in one image, but that is clear in another? (Sorry. Awkwardly worded question) I think some of the newer smartphones do something like that. You're not guessing at what ought to be there. In some of the old TV shows I watched as a kid (eg. MacGyver) they would take an old grainy closed circuit TV recording and "zoom in" and "enhance" auto-magically creating pixels out of thin air. Early up-scaling I suppose.

But, dude, seriously. You worked on Hubble?!

Amen. I am in a holding state hoping for a desktop+mobile management solution for passkeys with Keepass compatible apps, or Bitwarden. I have dozens of TOTP codes already (even this forum in fact). Some sites where I have TOTP configured seem to disable it if I go the passkey route.

I'd have to think some hierarchy such as : Passkey + TOTP > Password + Passkey > Password + TOTP > Passkey >> Password
