SoundLogin – two-factor authentication via sound notifications

In plain words

SoundLogin is a two-factor authentication system that uses sound notifications to verify user identity. Launched in 2015, it provides an alternative security method for people who need to authenticate their accounts. Rather than traditional text codes or app-based verification, the system relies on audio signals to confirm login attempts, offering a different approach to account protection.
