Google Chrome - Google Password Manager
Setup
To register a new passkey, first sign in to your profile. Then, navigate to Security > Login options in the main menu on the left-hand side. On the "Login options" page, locate the green "REGISTER A NEW PASSKEY" button and press it.
After you click the "REGISTER A NEW PASSKEY" button, a "Windows Security" modal window will appear, suggesting you use your authentication device, for example, your fingerprint reader. Press the cancel button.
Next, a new modal window will appear in your browser, asking where you'd like to save your Passkey: either in "Google Password Manager" or Windows Hello. Please select "Google Password Manager," which should be listed with your email address below it.
The next modal window will prompt you to create a Passkey.
And immediately after that, the "Windows Security" modal will appear, asking you to place your finger on the fingerprint scanner to scan it.
Provide a custom alias for your device (Optional)
Done! You've successfully saved your Passkey in “Google Password Manager”. 🎉
