Mini Authenticator is a minimal open-source authenticator for Chrome that provides secure and offline generation of time-based one-time passwords (TOTP) for two-factor authentication (2FA). Developed by hoishing, this extension prioritizes simplicity and security by never storing your secret keys.

With Mini Authenticator, you can generate TOTP passcodes without granting any special permissions. Simply paste your secret key into the extension and it will generate the corresponding passcode. The extension does not store your keys in any location, ensuring the security of your sensitive information. Additionally, no data is transmitted over the internet, making it an offline solution.

One of the key advantages of Mini Authenticator is its open-source nature. The source code is available for anyone to review and ensure its integrity. This transparency allows for community inspection and potential improvements in the future.

If you are already using password managers like Bitwarden or Apple Keychain to manage your secret keys and are looking for a simple and secure TOTP generator, Mini Authenticator is the perfect solution. It eliminates the need for additional features provided by other authenticators and focuses solely on generating TOTP passcodes.
