If you use "OK Google" to access the wizard on your phone, things will change. Google removes the "Unlock with Voice Match" feature, making it much safer.
If you're using the "Unlock with Voice Match" feature, you can now fully unlock your phone with Google Assistant. Simply, "OK, Google." While that's handy, it's also a pretty big security risk ̵
But now Google removes this feature from all Android phones. It started with the Pixel 3 and 3 XL, but confirmed that it will be possible on all other Android devices in the future – a future that seems to have come. The Moto X and Pixel XL are the first devices to lose this functionality, so it should not take too long before being removed on other devices.
With this increase in security you also get a loss of functionality. Everything you would need to unlock your phone. For example, sending a text message is no longer an option. No doubt this is a kind of joke, but it's a compromise that's worth it.
Without the Voice Unlock feature, the wizard is limited to "personal results". According to 9to5Google, this includes:
- email, including personal Gmail results, such as flight reservations and invoices
- Google Calendar
- Storage Aids
- Anything For more the phone will be unlocked, before you can continue. Similarly, after entering the wizard, you can no longer tap the Start button to go straight to your home. You must first unlock the phone with PIN, pattern, passwords, or biometric verification.
