Voice Passwords: Definition, Security & How They Work

Okta's cloud-based authentication gives users high-assurance with simple-to-use factors like biometrics and push notifications.

Voice password usage is relatively low, when compared to traditional (typed) versions. But this technology could be coming to an account near you. Almost 40 per cent of Internet users use a voice assistant (like Alexa) each month. We bark into our computers, speakers, and handheld devices, and we get the results we want. That same technology could be used to unlock your phone, open your bank account, or more.

  • Identify. With that data, you have created a voice password. 

In the future, programmers may create text-independent speaker verification. Your device will listen in as you speak normally in a variety of contexts. That information will create your voice ID.

3 benefits of voice biometry

Your typed passwords may seem adequate for now. Why should you set up a voice password?

These three benefits may entice you:

  1. Simplicity: You don't need fancy software to help you remember your password, and you don't need a high-end microphone to record the data. You have everything you need within your device. 
  2. Ease: About 70 per cent of consumers say biometrics (like voice passwords) are easier than traditional versions. 
  3. Security: Your voice is as unique as your fingerprint, and it's harder to steal. When combined with another factor (such as a traditional password), voice version
