Google has revealed upgrades for a number of its key apps, including a significant boost to its Password Checkup password manager service as it aims to keep all Android users safe online.

Password Checkup will now be able to see if any passwords for online accounts accessed on your Android smartphone have been compromised or stolen, for example in a data breach or cyberattack.

If this is the case, Password Checkup will now immediately alert users to the risk, prompting them to change their details straight away - and what's even better, it will now work across all your apps.

Password Checkup

Going forward, Password Checkup, which was first launched in October 2019 for Google Chrome only, will be integrated into Google's Autofill service, which lets users quickly enter login and password information online.

Google says the update will make it quicker and easier to sign into your apps and services using Autofill. Now, whenever a user enters a password into an app on their phone using Autofill with Google, it will be checked against a list of known compromised passwords, including those that have potentially already been stolen and posted on the web. 

If a user's credentials show up on one of these lists, they'll get a popup notification alert, with Google then instructing you to check their password and how to change it.

"With the proliferation of digital services in our lives, it’s more important than ever to make sure our online information remains safe and secure," wrote Arvind Kumar Sugumar, Software Engineer, Android Team in a blog post announcing the news. 

"Passwords are usually the first line of defense against hackers, and with the number of data breaches that could publicly expose those passwords, users must be vigilant about safeguarding their credentials."

The Android system uses the same privacy preserving API that powers Password Checkup in Chrome, and ensures that only an encrypted hash of the credential leaves the device, and that the actual determination of whether the credential has been breached happens locally on the user’s device - meaning Google never has access to the unencrypted hash of the user’s password.

Password Checkup is available to Android 9 users and later - for anyone looking to enable Autofill with Google on your Android device, simply open your phone’s Settings app > tap System > Languages & input > Advanced, tap Autofill service, tap Google to make sure the setting is enabled.
