We've added two new security features for billing accounts this week.
- Login notification emails. This feature is not optional and is enabled for all clients. Every time your billing account is signed in to, you will receive an email with the IP address and user-agent of the device that signed in.
- Yubikey 2FA support. We already have standard 2FA code authenticator support, but we enabled Yubikey 2FA support now. If you have a Yubikey device you can enable this from the Profile -> Security Settings page.
