## More places to setup MFA
### Windows
Yubico has a dedicated [Credential Provider](https://docs.microsoft.com/en-us/windows/win32/secauthn/credential-providers-in-windows) that adds Challenge-Response authentication for the username + password login flow for local Windows accounts. If you have a YubiKey with Challenge-Response authentication support, take a look at the [Yubico Login for Windows Configuration Guide](https://support.yubico.com/hc/en-us/articles/360013708460-Yubico-Login-for-Windows-Configuration-Guide), which will allow you to set up MFA on your Windows computer.
### macOS
macOS has [native support](https://support.apple.com/guide/deployment/intro-to-smart-card-integration-depd0b888248/web) for authentication with smart cards (PIV). If you have a smartcard or a hardware security key that supports the PIV interface such as the YubiKey, we recommend that you follow your smartcard/hardware security vendor's documentation and set up second factor authentication for your macOS computer.
Yubico have a guide [Using Your YubiKey as a Smart Card in macOS](https://support.yubico.com/hc/en-us/articles/360016649059) which can help you set up your YubiKey on macOS.
After your smartcard/security key is set up, we recommend running this command in the Terminal:
```text
sudo defaults write /Library/Preferences/com.apple.loginwindow DisableFDEAutoLogin -bool YES
```
The command will prevent an adversary from bypassing MFA when the computer boots.
### Linux
!!! warning
If the [hostname](https://en.wikipedia.org/wiki/Hostname) of your system changes (such as due to DHCP), you would be unable to login. It is vital that you setup a proper hostname for your computer before following this guide.
The `pam_u2f` module on Linux can provide two factor authentication for user login on most popular Linux distributions. If you have a hardware security key that supports U2F, you can set up MFA authentication for your login. Yubico has a guide [Ubuntu Linux Login Guide - U2F](https://support.yubico.com/hc/en-us/articles/360016649099-Ubuntu-Linux-Login-Guide-U2F) which should work on any distribution. The package manager commands such as "apt-get" and package names may however differ. This guide does **not** apply to Qubes OS.
### Qubes OS
Qubes OS has support for Challenge-Response authentication with YubiKeys. If you have a YubiKey with Challenge-Response authentication support, take a look at the Qubes OS' [YubiKey documentation](https://www.qubes-os.org/doc/yubikey/) if you want to set up MFA on Qubes OS.
### SSH
#### Hardware security keys
SSH MFA could be set up using multiple different authentication methods that are popular with hardware security keys. We recommend that you check out Yubico's [documentation](https://developers.yubico.com/SSH/) on how to set this up.
#### Time-based One-time Password (TOTP)
SSH MFA can also be set up using TOTP and DigitalOcean has provided a tutorial [How To Set Up Multi-Factor Authentication for SSH on Ubuntu 20.04](https://www.digitalocean.com/community/tutorials/how-to-set-up-multi-factor-authentication-for-ssh-on-ubuntu-20-04). Most things should be the same regardless of distribution, however the package manager commands such as "apt-get" and package names may differ.
### KeePass (and KeePassXC)
KeePass and KeePassXC databases can be secured using Challenge-Response or HOTP as a second factor authentication. Yubico has provided a documennt for KeePass [Using Your YubiKey with KeePass](https://support.yubico.com/hc/en-us/articles/360013779759-Using-Your-YubiKey-with-KeePass) and there is also one on the [KeePassXC](https://keepassxc.org/docs/#faq-yubikey-2fa) website.

## More places to setup MFA
Beyond just securing your website logins, multi-factor authentication can be used to secure your local logins, ssh keys or even password databases as well.
