CLUSTER AUTHENTICATION-FACTOR-GENERATES-2 · 6 ENTRIES · EARLIEST ENTRY 2012-08-23
OTP authenticator apps
This cluster consists of desktop and mobile applications for generating one-time passwords (TOTP, HOTP, and occasionally MOTP) for two-factor authentication. They typically offer encrypted local storage, backup/import/export, QR-code setup, and offline operation. Dated entries appear in seven distinct months spread across 2012 to 2026, showing no consistent pattern. All three traction leaders (OTPClient, Mauth, Secure Authenticator: 2FA) show zero stars, indicating no clear market leader yet.
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 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.
