Two-factor authentication apps

These are mobile apps that generate one-time passwords for two-factor authentication, typically using time-based or counter-based algorithms, with many supporting offline storage and multiple accounts. The dated history shows a steady, low-volume stream of entries from June 2009 to May 2026, with one or two entries in most months, rather than any pronounced pattern. Traction is led by gil-otpapp-ios with 2 stars, followed by laravel-totp with 1 star and Authenticator: 2FA Authy & MFA with 0 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.
