Smartphones are a big part of our lives today, and the best smartphones serve as more than just phones. They hold memories like photos and videos but also protect other important things, like passwords and confidential apps. Many of us have banking apps or investing apps on our phones, and allowing the wrong person access to those apps could be detrimental to our online security portfolio. Luckily, there are steps you can take to secure applications on the best Android phones, including locking applications individually.
Of course, smartphones have passcodes or biometric security measures that keep unwanted people out. But for added security, you can individually lock certain applications. There are built-in ways to do this in the operating system, but there are also third-party solutions as well. However, it should be noted that locking applications is not supported in stock Android. However, the feature is set to appear in Android 15. This guide explains both ways and goes through the steps for each smartphone manufacturer. Take a look at what smartphone brand you have, and skip to the instructions tailored to that manufacturer.

Use third-party app locks
Not all phones offer a built-in app lock feature. If you have a Google Pixel or a phone that runs stock Android, such as Motorola, you’ll have to explore third-party app locks to get the job done. There’s no shortage of app locks on Google Play Store, but you have to be careful when choosing one. While they may all serve the same purpose of protecting your apps, some may collect and share your data with third parties for targeted marketing purposes.
App Lock – XLock by InShot Inc. and Norton App Lock by Norton Labs are two solid options. Not only do they have an intuitive user interface and onboarding experience, but they also don’t share your data with advertisers. Here’s how to use to protect your apps and data using a third-party app lock.
1. Download App Lock by InShot Inc. from the Google Play Store.
2. Open the app and tap Start Now to get started.
3. To use the fingerprint you have already registered on your phone, click OK.
4. Set up PIN or pattern as a fallback option.
