SecondFactor is a two-factor authenticator app for your PC.

Having a 2FA app will significantly improve your security protocols if you work with sensitive data on your machine that you wish to keep secure. SecondFactor is designed to be a one-time password authenticator that supports time-based passwords you can add directly, by QR Code, or with an OTPAUTH URL. Your secrets are stored securely in your local account. There is an option for total account password protection for added security.

The interface is compact, with the main windows providing access to multiple authentication profiles and lists not only the current code but the last code and subsequent as well. SecondFactor supports SHA1, SHA256, and SHA512 with six or eight-digit codes. There is also a rolling time period available. Standard defaults are selected automatically. More details here.

SecondFactor is an excellent, easy-to-setup choice for adding another layer of security to your machine.
