Google Authenticator is a free, open-source authentication app that generates time-based one-time passwords (TOTP) to provide an extra layer of security for your online accounts. By utilizing a unique verification code that changes every few seconds, it safeguards your accounts from password-only breaches. This tool is particularly useful for services that require more than just a password for login, thereby ensuring that your digital presence remains secure. Google Authenticator's ease of use and widespread adoption make it a staple in the digital security landscape.
