 ### 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.

 This may be impractical, so consider whether it's worth it, but in either case even AFU mode is effective against most threats, given you are using a strong encryption key.
