Method 1: Using the terminal ======================= LUKS allows for an encrypted partition/system to have multiple passwords and also to remove them. So to change the password we first add the new password and then remove the old one. - Get the name of the encrypted volume Open the terminal application [[ https://tracker.pureos.net/w/pureos/desktop/terminal_emulator/ | Tilix ]] and type the command: {icon terminal} `lsblk` It will show you the name of the partition, ignore `/boot` and `/swap` {F289726, width=790, alt=cdp1} NOTE: In this case the encrypted volume is called `sda2`, but on your machine it can have a different name. Make sure you adjusted these commands to with the name of your device! **Add a new password** - In `Tilix` run the command: {icon terminal} `sudo cryptsetup luksAddKey /dev/device_name` - It will ask you for your user password, type it and press enter. {F289734, width=790, alt=cdp1} - Next you will be asked for the old disk encryption password, type it and press enter. {F289737, width=790, alt=cdp1} - Type the new password you want for the encrypted disk, and press enter {F289739, width=790, alt=cdp1} - Confirm the new password and press enter {F289741, width=790, alt=cdp1} The new password is now added {F289743, width=790, alt=cdp1} **Removing the old password** From `Tilix` run the command: {icon terminal} `sudo cryptsetup luksRemoveKey /dev/device_name` {F289746, width=790, alt=cdp1} - Type the password that you want to delete and press enter {F289754, width=790, alt=cdp1} --- Method 2: Using GNOME DISKS ============================ IMPORTANT: Because of the bug: https://tracker.pureos.net/T541, please DO NOT USE THIS METHOD on PureOS 9 ("amber") for now! You will lose access to your encrypted disk. If you are using PureOS 10 ("byzantium") this method is safe. Start up ** GNOME Disks** and click the encrypted volume you wish to change the password for, click the gear icon and select //Change Passphrase...//: {F28791, size=full, alt=cdp1} Enter your current and new password, and that's it: {F28792, size=full, alt=cdp2}
