Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 37 of the 52 answers that named Microsoft Authenticator and are not a share of its labels.
121 of the 132 domain citations in answers naming Microsoft Authenticator came from somebody else's page.
Pages are listed as the models cited them.
