Touch ID in macOS Mojave looks to be getting a handy new update. With the release of the first beta of MacOS 10.14.4 last week, Touch ID has been expanded to support Safari Autofill functionality. This should make things more secure should you leave your Mac unattended (don’t do that!) with Safari open.
Currently in Safari, you can use the Autofill feature to fill in forms, usernames, passwords on web pages that you visit. This can include information from contacts or credit card information that is stored in the feature. If you haven’t tried it out, you can enable it via Preferences in Safari.
In MacOS Mojave 10.14.4 beta 1, a new feature has been added to Touch ID, which is Safari Autofill. Now by touching the sensor on your MacBook, you can have all these forms filled in automatically in Safari with a single touch. It will make the Autofill feature more secure but also will save you time as you surf around to various sites.
By-the-way, Touch ID preference are found in System Preferences in Mojave but it will only appear if you have a compatible MacBook with the touch sensor.
We are still likely several weeks away from macOS Mojave 10.14.4 being released to the general public as it just entered beta last week. Generally Apple issues four to six beta builds of the platform before releasing it. Doing the math, that puts it roughly at the end of February or early March for a release date.
