Google Chrome will soon have an experimental feature to prevent users from accessing Incognito tabs on Android without inputting the correct password or authenticating themselves via fingerprint detection.
Incognito mode won't be accessible if your phone's facial detection feature doesn't recognize you. Also, if its fingerprint reader doesn't detect your fingerprint or the passcode you enter doesn't match.
However, this could be a bit of a payoff. Many users prefer to keep the standard and incognito tabs open so that they can access them quickly. As a result of this increased authentication level, there is some delay in accessing it.

It is possible to prevent your online activity from being saved to your history by using Chrome's Incognito Mode, similar to other browsers' Private Browsing Mode. It's a good thing, but it's not 100% secure.

However, for all Incognito users, this new function is a vast privacy gain. If someone has access to your phone, they can breach and snoop into the sites you're attempting to keep private. Even if your phone is password protected or has biometric security, getting into it is very easy! If you give it to someone unlocked for even a short time.

While a new flag (incognito-reauthentication-for-android) has been added to Chrome Canary, the feature appears to be disabled for the time being (2021 August). Google may either offer the option in a future Canary build update or through a server-side update.

Google Chrome for Android will have this feature in a few months instead of weeks, so don't worry about it now! As a result, it will first be tested on Chrome Canary and Beta users who want to try out pre-released apps.

Because this feature was first introduced on iOS, many users are not surprised that it is now available on Android. However, the incognito lockdown feature appears to be limited to mobile devices for the time being.

This makes it logical, as iOS and Android offer various security alternatives, such as fingerprint sensors.

Desktops and laptops are not guaranteed to get the new feature. Furthermore, locking tabs with a password is a less handy option that Google would not want to adopt for desktop users.


Incognito's impact on iOS and Android users
Incognito mode users on Android and iOS will be a little more secure with this new functionality shortly. Of course, someone might know your phone's password, but spying into your browser history could be a challenging challenge for them.

Incognito mode makes it easier to hide your browsing history from those around you. However, your Internet Service Provider (ISP) can still monitor what you're looking for.

While this may sound scary, a quick answer is to use a trusted VPN service to prevent this from happening.
