Title pretty much says it all. I have a secondary storage HDD that I want mounted on start up, but it asks for a password every boot. In gnome I could set it to automount without asking, but in KDE I can't seem to find a way to do it.

Any suggestions to try?

It sounds like you have a regular partition (maybe EXT4 format) inside of an encrypted volume.

I have a bunch of these. Here’s an example of how I set one of them up to auto mount.

I make an entry in /etc/crypttab to tell the OS to open the encrypted volume on boot.

storage_003_cryptpart UUID=4be15e12-fd47-34e1-7abf-f2b265b34e31 /etc/luks-keys/storage_003_cryptpart luks,auto

/etc/luks-keys/storage_003_cryptpart is a file that contains nothing but the key (passphrase) for the encrypted volume. I keep that readable only by root and it’s in the main encrypted volume so it can’t be read unless the machine is up and running.

Then I have an entry in /etc/fstab that tells it to auto mount the EXT4 partition inside of that encrypted volume.

UUID=3373a107-ede9-4f17-d0f3-229a38c52e2e /media/storage_003 ext4 user,auto,noatime,rw,exec 0 0

To get the UUID of your encrypted volumes and regular partitions enter lsblk -f

For that drive lsblk -f shows this:

sdb
└─sdb1                     crypto_LUKS 2              4be15e12-fd47-34e1-7abf-f2b265b34e31
  └─storage_003_cryptpart  ext4        1.0            3373a107-ede9-4f17-d0f3-229a38c52e2e      3.4T    48% /media/storage_003

The UUID next to crypto_LUKS2 goes in /etc/crypttab. The UUID next to ext4 is used in /etc/fstab.
