2FAu Authenticator от JiLiZART

2FAu is a fast, local-first authenticator for your two-factor (TOTP/HOTP) codes.

Your accounts live in an encrypted vault right in your browser — there is no
account to create and no server to breach, and your secrets never leave your
device.

Features
• Encrypted vault (AES-256-GCM) unlocked by a single passphrase
• Popup with colour-tinted rows and search-as-you-type
• Hotkeys: open the vault (Ctrl/Cmd+Shift+U), copy a code (Ctrl/Cmd+1–5),
autofill the focused field (Ctrl/Cmd+Shift+Y)
• Enroll by scanning a QR straight off the current tab — no phone needed
• Sync as encrypted chunks through your browser profile, or point it at your
own 2FAu desktop app over loopback
• Same Rust crypto core as the 2FAu desktop app for macOS, Windows and Linux
• Open source (MIT)

2FAu never sends your codes or secrets anywhere. No tracking, no analytics,
no data collection.
