CLUSTER TIME-FACTOR-AUTHENTICATION · 44 ENTRIES · EARLIEST ENTRY 2016-09-28
TOTP authenticator apps
This cluster consists of mobile authenticator apps that generate time-based one-time passcodes for two-factor authentication, typically by scanning QR codes or entering secret keys, with some offering encrypted backup sync and account organization. The dated history spans from October 2013 to July 2026, with 29 dated entries appearing sporadically, often one per month and occasionally two, yielding no clear trend shape. Traction leaders are Authenticator App - 2FA ◦ MFA, Internet Protection App 2FA+, and H1 Authenticator, each with zero activity stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 4 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
