## プロジェクトの歴史と使われ方

cotp is a command-line TOTP/HOTP authenticator aimed at users who want two-factor codes in a terminal-accessible, encrypted local database. Its niche is the intersection of password-manager-like local storage and Unix-style CLI workflows.

### プロジェクトの歴史

The replydev/cotp repository was created in December 2020 and published its first GitHub release later that month. The README says the author created cotp to have minimalist, secure, desktop-accessible software for managing two-factor authentication codes.

### 採用の歴史

The project has remained a smaller security utility rather than a large platform. Its README notes distribution in Linux distro repositories and gives Homebrew, Cargo, and manual source installation paths, which is typical for Rust command-line tools that serve both desktop and shell users.

### 使われ方

cotp initializes an encrypted database on first run, displays OTP codes in an interactive dashboard, can add TOTP and HOTP entries, lists records as JSON, imports encrypted Aegis backups, exports its database, and can copy selected codes to the clipboard.

### パッケージ好きにとっての重要性

For package nerds, cotp is notable because it packages sensitive local credential material without depending on a cloud account. The distribution concern is less about daemons or services and more about preserving a stable CLI, encryption format, clipboard integration, and migration/import behavior.

### タイムライン

- 2020: replydev/cotp repository created and first release published.
- 2020: README documented encrypted database storage and import/migration from other authenticator apps.
- 2026: Project continued publishing releases.
