Our verdict on 2FA Authenticator
2FA Authenticator is a free, open-source Chrome extension for generating TOTP and HOTP two-factor authentication codes locally. It is aimed at individuals who want browser-based code generation without an account, with secrets remaining on the device. Setup supports QR-code scanning, screenshot upload, and manual secret-key entry, while account grouping, search, and sorting help organize multiple credentials. Codes can be copied or inserted directly into editable login fields from Chrome.
Its strongest fit is a local, offline workflow with practical migration options. The extension can import and export otpauth:// links and CXF files, including compatibility with Google Authenticator, Authy, Microsoft Authenticator, and 1Password. Optional password protection uses AES-256-GCM encryption, and automatic local backups retain seven days of snapshots. Optional Chrome Sync can synchronize accounts across Chrome browsers, giving users a browser-centered way to access their credentials without turning the product into a separate hosted service.
The published plan structure is simple: the Free plan includes TOTP and HOTP codes, offline operation, encrypted password protection, automatic local backups, and optional Chrome Sync. There is no paid tier to evaluate, but the platform scope is narrow. Chrome extension coverage suits users who keep authentication close to their browser; it is less suitable for people who need a dedicated mobile or desktop authenticator, push approvals, or team administration. Choose it for local control and open-source transparency within Chrome, and consider an alternative when broader device coverage or managed authentication workflows are priorities.
