what it is, how it works and how you can use it to sync your passwords

22 mayo, 2021

One of the easiest ways to protect our accounts is to use a strong password, preferably a different one for each service. That, of course, means having to remember several passwords, which can be somewhat complicated if we use many different services, platforms and applications. But for that Google has a solution: Smart lock.

The good thing about this system is that it does not work only on PC, but syncs with any Android mobile Through the Google account Today we are going to get to know it better, we will see how to configure it and, of course, how to take advantage of it on our smartphone.

What is and how does Google Smart Lock work?

In a nutshell, Google Smart Lock is a vault of passwords stored in your Google account. Surely you have noticed that when you log into a website through Google Chrome (either on PC or mobile), it asks you if you want it to remember your credentials to fill them automatically the next time. Smart Lock is exactly that.

It arrived on June 1, 2015 in version 7.5 of Google Play Services and in just four years it has become the default password manager for all Android phones. Your device has to be very old so that it does not support Google Smart Lock.


Its operation is extremely simple and the first thing to do is make sure you have it activated. To do this, open Google Chrome on your computer and make sure that is syncing with your Google account. You can do this by clicking on your profile photo, in the upper right corner of the browser. If there is a green icon next to the photo, it means that syncing is activated.

Now, go to your mobile and follow the following route: Settings> Google> Smart Lock for passwords. For the sync to work, you must check the “Smart Lock for passwords” box. In addition, Google Smart Lock allows you to automatically log in to those applications that support it. Netflix and Spotify are among them, for example. To do this, you will also have to check the “Sign in automatically” box.

And how is it used?

We already know Google Smart Lock, but how will you know it is working? Easy, because when you open the application a blue box at the bottom indicating your username. In the case of Spotify, if you have the password saved, as soon as you open the application, the session will start without any type of intervention on your part.

Also works on web pages when we use the Google Chrome browser. If you have the credentials saved in the account, when you open a website an icon of a key will appear above the keyboard. By clicking on it, the account in question will be displayed. If you select it, the “username” and “password” fields will be filled in automatically.

Now, it is important to highlight one thing: you can only have one account saved for each service or platform. You cannot have multiple Facebook accounts, for example, just one. If you want to delete the saved account to make room for another, you will have to go to, log in with your Google account and delete it manually.

As you can see, it is a very useful tool for those who have accounts in several services and want to use strong passwords without having to remember them by heart. However, it involves its risks, since if you leave the phone to someone, they can log into your accounts with the same ease as you.

If you want to avoid this, you can use another alternative password manager like LastPass. The advantage of this type of manager is that it allows establishing a fingerprint lock to access the app and fill in the login fields, which adds an extra layer of security.
