How to enable MFA for the zerotier.com?

hello,

i cannot figure out how to protect the website using some kind of MFA?
where is the feature?

Go to the “Account” tab once logged in:

Click the “Manage Account” link. Once in there, under “Account Security” you’ll find options to set up 2FA via authenticator application or FIDO2/WebAuthN hardware token.

thank you 20characters
