The A11 devices - iPhone 8 to iPhone X users cannot use the passcode /FaceID and Touch ID after jailbreaking from the Palera1n jailbreak tool. This is a huge issue for A11 users who cannot secure their devices.
However, some popular jailbreak tweak developers released a solution for this issue. The check4round and Checkl0ck tweaks support to get passcode / Touch ID and FaceID back to the Palera1n jailbroken devices.
