Secure your Manjaro disk by using proper decryption methods.
Secure your Manjaro disk by using proper decryption methods.
During installation I enabled full disk encryption on Manjaro, but starting the computer often becomes slow when decrypting. If I misremember the password, I’m redirected to Grub Rescue. I’m looking for a quicker decryption method and a way to re-enter the password after an incorrect attempt.
It seems Manjaro is applying similar changes for me, likely on purpose. Switching the encryption method might be possible but would reduce security. You could probably switch to a different encryption scheme, though this would remove data from the filesystem. This is due to Manjaro encrypting /boot as well, which is a system-level feature (intentionally because the UEFI depends on your OS kernel for scheduling). Full disk encryption is available, and you can install Manjaro with only root encrypted—essentially making it behave like Arch Linux at that stage.
If Grub is secured, it relies solely on a specific filesystem and cannot store data in memory, meaning incorrect passwords will force a restart.
Consider pausing the system instead of stopping it completely. Activate the auto-logic feature from the login manager (not ideal for portable devices, but acceptable for a desktop).
