Tailscale doesn't want your password

Tailscale now supports passkeys as the newest way to authenticate to your tailnet. Passkeys let you extend your tailnet to users beyond your identity provider, without worrying about weak or reused passwords. This also means that if you are on the Free plan and you’re using a single user email account to authenticate — like Gmail — you’ll now be able to invite other users to your tailnet with a passkey.
