The risk there is more you accidentally make a bad comment on YouTube and Google bans your account, I think. I have no idea if I'd still be able to access my passwords if that happens. At least, personally I feel Google deciding to disallow me from logging in is more likely than Google losing my passwords.
Is there a local UI to view/export your passwords? The only one I'm aware of is https://passwords.google.com but it's been a long time since I've used a builtin browser password manager.
also- does Google (or other browser devs) release information on how they keep your passwords secure? Is it even E2EE?
