Phone-Free 2FA

Purpose: Phone-Free 2FA generates time-based one-time passwords in a browser so users can get login codes without reaching for a phone.
Code generation: It generates a new six-digit code every 30 seconds and lets users copy it from the browser sidebar.
Compatible accounts: It works with services that provide standard TOTP authenticator codes, such as Microsoft 365, and does not receive push-approval requests.
Browser availability: The project lists installs for Chrome and other Chromium browsers, including Edge and Brave, and for Firefox.
Local storage: Account details are encrypted and stored locally in the browser, and the extension says it sends nothing over the network.
Encryption: The Chrome Web Store listing says secret keys are encrypted with AES-256-GCM using a key derived from the master passphrase with PBKDF2 at 600,000 iterations.
Unlock protection: The extension can lock when the sidebar closes or after configurable inactivity, and failed unlock attempts trigger progressively longer delays.
Biometric unlock: Touch ID is available on supported Chrome and Edge devices; Firefox users unlock with their master passphrase.
Backups and migration: Users can export encrypted backups and export standard otpauth records to move accounts to another authenticator.
Recovery limit: There is no central passphrase reset or recovery; without a usable backup, stored accounts cannot be recovered through the extension.
Organisation limits: The project has no backend, tenant, administrator account, central recovery, cross-device sync, or administrative view of users’ accounts.
Intended users: The maker says it can help staff who need TOTP codes during computer-based work without keeping a phone beside them.
Maker: The product is developed by Centre for Digital Habits with computer scientists at the University of Oxford and Maastricht University.
Support: The maker directs users to the project’s GitHub repository for questions, suggestions, problems, and contributions.
