Can’t get KDE Wallet to auto unlock with blank password

I have been using both KDE Plasma 6.0 and 6.1 and I am trying to get KDE Wallet to auto unlock while also having auto login enabled in sddm. If I set the wallet password to the same as my user password it will auto open when I am logging in manually with my password. However, I understand that having auto login enabled makes it impossible to auto open a password protected wallet.

The solution that I have found on ArchWiki and other places is to set a blank password for ‘kdewallet’ using KWalletManager. This does not seem to work for me. Even though I have set a blank password for ‘kdewallet’, the wallet won’t auto open when using auto login (or when logging in manually for that matter).

How can I have auto login enabled with sddm and get KDE Wallet to auto unlock?

See this
* Did you configure /etc/pam.d/sddm accordingly? Can you attach the output here?

Re: Can’t get KDE Wallet to auto unlock with blank password

I'm also having an issue with kwallet, but interestingly with a reversed phenomenon than @sausge's. It works fine if I set `kdewallet` password to be blank; but it does not unlock automatically when I set the `kdewallet` password to be the same as login password. I followed the instructions. To make sure, I also deleted and re-created the `kdewallet` with blowfish encryption.

Here's my /etc/pam.d/sddm

#%PAM-1.0

auth        include     system-login
-auth       optional    pam_gnome_keyring.so
-auth       optional    pam_kwallet5.so

account     include     system-login

password    include     system-login
-password   optional    pam_gnome_keyring.so    use_authtok

session     optional    pam_keyinit.so          force revoke
session     include     system-login
-session    optional    pam_gnome_keyring.so    auto_start
-session    optional    pam_kwallet5.so         auto_start

And I don't see error in log as well:
