How secure are your passwords? You probably know that you should create strong passwords and never re-use them across different websites and services. If you store passwords in Chrome on the desktop you may know that your browser has a password checkup tool built in. Google has now added the Password Checkup tool to Android as well.
What to know about Google’s Password Checkup for Android devices
Google’s Password Checkup is built into your Android phone as long as you are running Android 9 or higher, and it is built into the Autofill with Google settings, which means if you are using a different service to autofill passwords (such as Dashlane or Bitwarden) it won’t work.
The Password Checkup is designed to keep you safe by comparing your stored passwords against an online database of known data breaches and exposed passwords. Whenever you enter or save a password, it tests your entry and if a match is found, your phone will show you a warning and advise you to change the password. You can also manually review all your stored passwords and perform a password checkup as well.
For the safety and security of your passwords, they are never transmitted to the cloud unencrypted. Instead, Google only uploads encrypted versions of your passwords to compare your passwords to its online security database, and the actual determination of whether your credentials have been compromised happens locally on your phone, not in the cloud.
