Firstly, app passwords generated for an email client (like Outlook) have a tendency to randomly stop working after a period of weeks, forcing me to generate a new app password and update the Outlook account settings. This is an annoyance. With no change of device or application, the app password should continue to work indefinitely.

Secondly, when I generated a new app password today, I found that I can no longer delete the old, outdated app password entries. I click "Delete" next to the outdated description and then "Delete" in the pop-up confirmation window. The button changes from red to blue, but the deletion never occurs. It's now impossible to clean up outdated entries. I've tried both Chrome and Edge (current builds) on two different Windows PCs and one Android phone. No luck. The Manage App Passwords feature is clearly broken.

Thirdly, as a usability enhancement, the option to either Regenerate or Delete an existing app password entry should be implemented rather than forcing users to delete the old one and create a new one. In this way, when a user gets a new device or email client that replaces an existing one, they can simply update the generated app password (single-step fix).
