While true, it still means you're locked into only being able to log in from a browser that has the password manager extension installed and logged in. Sometimes I want to log in from another machine, or another OS, or another browser, or even an incognito window that doesn't have access to my extensions.

KeepassDX as well.

Yeh, I have passkeys in bitwarden.
I get it. Once they become ubiquitous, you click "login" your password manager prompts you to select account, and you are in.
No password that can be leaked, incorrectly stored, brute forced.
Corporations can pre-register company service passkeys for new users.
It's like mTLS, except staged.
