Most computers and phones come equipped with a TPM (or a similar secure cryptoprocessor) which safely stores your encryption keys and handles other security-related functions. If you're currently using a machine that doesn't have one of these, you might benefit from purchasing a newer computer that has this feature. Some desktop and server motherboards have a "TPM header" which can accept a small accessory board containing the TPM.

Most implementations of face authentication require you to be looking at your phone and also only work from a relatively close distance, so you don't need to worry too much about someone pointing your phone at your face to unlock it without your consent. You can still disable biometrics when your phone is locked if you want. On iOS, you can hold the side button and a volume button for 3 seconds to disable Face ID on models that support it. On Android, hold the power button and press Lockdown on the menu.

Android defines three [security classes](https://source.android.com/docs/security/features/biometric/measure#biometric-classes) for biometrics; you should check that your device is Class 3 before enabling biometrics.
### Device Encryption
If your device is [encrypted](../encryption.md), your data is most secure when your device is completely powered off (as opposed to merely asleep), i.e. before you've entered your encryption key or lock screen password for the first time. On phones, this state of higher security is referred to as "Before First Unlock" (BFU), and "After First Unlock" (AFU) once you enter the correct password after a reboot/power-on. AFU is considerably less secure against digital forensics toolkits and other exploits, compared to BFU. Therefore, if you are concerned about an attacker with physical access to your device, you should turn it off fully whenever you aren't using it.

Hardware keys are devices that use strong cryptography to authenticate you to a device or account. The idea is that because they can not be copied, you can use them to secure accounts in such a way that they can only be accessed with physical possession of the key, eliminating many remote attacks.

### Camera/Microphone
If you don't want to trust your OS's permission controls to prevent the camera from activating in the first place, you can buy camera blockers that physically prevent light from reaching the camera. You could also buy a device that doesn't have a built-in camera and use an external camera that you can unplug whenever you're done using it. Some devices come with built-in camera blockers or hardware switches that physically disconnect the camera from power.

Alternatively, buy a device that doesn't have a built-in microphone and use an external microphone that you can unplug when you're done using it.

The most important thing to think about with routers is keeping them up-to-date. Many modern routers will automatically install updates, but many others won't. You should check on your router's settings page for this option. That page can usually be accessed by typing `192.168.1.1` or `192.168.0.1` into the URL bar of any browser assuming you're on the same network. You can also check in the network settings of your OS for "router" or "gateway".
If your router does not support automatic updates, you will need to go to the manufacturer's site to download the updates and apply them manually.
Many consumer-grade routers aren't supported for very long. If your router isn't supported by the manufacturer anymore, you can check if it's supported by [FOSS firmware](../router.md). You can also buy routers that come with FOSS firmware installed by default; these tend to be supported longer than most routers.

Some ISPs provide a combined router/modem. It can be beneficial for security to purchase a separate router and set your ISP router/modem into modem-only mode. This way, even when your ISP-provided router is no longer getting updates, you can still get security updates and patches. It also means any problems that affect your modem won't affect your router and vice versa.
