It's so weird because I can use the same API to log in on my Google account using my phone as a 2fa method on Opera as well. It shows me the same popup at the top center of the screen for me to add new devices or use my current device if there is an WindowsHello option for example

On Chrome there is a session on the settings called
chrome://settings/securityKeys/phones
On Opera we do have the same management for 2fa phones.
How can we manage the devices? I've changes my phone and my old one keeps appearing.
