Enabling biometrics for incognito browsing in Google Chrome will lock your Incognito Tabs. You are requiring unlocking them before you can see them again. If your device is being used by someone else, this is a great way to make sure no one else can see what you're doing.
1. Open Google Chrome on smart devices and access its settings.
2. Tap Privacy and security.
3. Tap "Lock Incognito tabs when you leave Chrome" once to enable it.
(You will be asked to authenticate with your fingerprint to confirm. If you use a pattern or pin lock on your smart device, you will instead be asked to enter those to authenticate.)
To disable the lock in incognito mode, just follow the same steps you did for enabling it and turn off the toggle for the Lock Incognito tabs when you leave Chrome option.
