Google Password Generator
First, make sure that password saving is enabled (it must be enabled by default). To verify, click on your profile picture in the upper right corner, and then click on "Passwords." You can also type in the Omnibox and press Enter.
Move the switch labeled "Offer to save passwords" to the on position (if not already).
Next, go to a website where you want to create an account. When you click on the password field, a pop-up window will suggest a strong one. Click on "Use suggested password".
If the message does not appear, right-click on the password field and then click on "Suggest Password". This will cause the pop-up window to appear below the field with a new password suggestion.
That's! Finish the registration process. After completing it, Google saves and stores the password so you don't have to remember anything.
How to change an existing password
If you didn't know this function when you created an account, you could still use it to change the password of an existing account and make it more secure.
Log in to the account with the password you want to change and go to the section where you can change / reset your password. After clicking on the "New password" field, a message with a strong password suggestion should appear. Click on "Use suggested password".
If you don't see the message, right-click on the password field and then click on "Suggest password".
Click "Use suggested password" when the message appears this time.
Click on "Save Changes" to change your password.
One caveat about using this feature to change the password of an existing account is that it may not be updated automatically in Chrome, in which case you will have to do it manually. However, this is not difficult. After saving the new password, before leaving the website, click on the key icon in the Omnibox, enter the username for that site and then click on "Update password".
Understandably, not everyone is delighted with the idea of Google handling their passwords. But Smart Lock for Passwords is a free and practical alternative for those who don't want to pay for a password manager or download additional software.
