Google Chrome is the most popular web browser in the world right now, so there’s a good chance you're using its integrated password manager already.
On desktop platforms, you’ll find it under settings - autofill - password manager. You can see all your passwords here, and search for them via their username or the web page they are used on. It will also show you any passwords that have been compromised, based on known data breaches and leaks.
There is also the Google Password manager, which is the official password manager for Android, and has now taken over the integrated manager in Chrome as well. This means it now stores passwords you use on Android apps as well, not just website passwords.
