Two-factor authenticator apps

This cluster consists of two-factor authentication apps that generate time-based one-time passcodes from QR codes or manual keys, with encrypted storage and backup features. The dated entries show an intermittent pattern, with a single entry appearing most months from February 2021 through February 2025, and two entries in June 2026. The strongest traction signal appears on TwoFactorAuth-Web with 7 stars, while Authenticator App © and Authenticator App₊ show zero stars.

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.
