CLUSTER TIME-FACTOR-GENERATES · 6 ENTRIES · EARLIEST ENTRY 2013-12-03

Offline 2FA authenticator apps

This cluster consists of desktop and mobile authenticator applications that generate time-based one-time passwords locally for two-factor authentication, emphasizing offline operation without network connectivity. The dated entries are sparse: one in December 2013, one in December 2019, two in 2020 (September and October), and one in July 2024, indicating a sporadic release pattern with long gaps. Traction is led by 2FAC with 5 stars, while other members have no activity signal.

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 6 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
