If you want to change it maybe tough. It doesn't have to be. Bitwarden has an open source self hosted option(you can also use their service), that can be set as provider in Android and Windows 11. KeepassXC is an option everything is in your kdbx file. Passkeys are so much more convenient and secure. If you do get stuck having to migrate, you can use your password (I would actually prefer just using multiple passkeys.) You don't need to do them all at once. Your average user is probably using whatever their device offers or nothing at all. I'd argue anyone that is tech savvy shouldn't be using either Google or Apple. If your account is disabled, you probably just lost anyway to retrieve your account unless you use a separate email address. I recently discovered cross device auth when a device I had a passkey was able to open my account on my pc that didn't have a passkey. TLDR ther are simple solutions that solve the 'lock in' issue.
