Two-factor authenticator apps
These products are authenticator applications that generate time-based one-time passcodes for two-factor login, spanning mobile, desktop, and self-hosted sync backends. Dated entries begin in April 2018 and appear periodically through March 2026, with a concentration of entries around mid-2024 and mid-2025. Traction signals are uniformly flat, with the three leading products (selfhostauth, avda-bin, Yubico Authenticator) all at 0 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.
