Broken for me as well on sddm 0.19. Downgrading fixed it. Added to IgnorePkg.

Auto-login isn't working for me with lxqt as my DE. I get the following messages:

sddm-helper[754]: PAM unable to dlopen(/usr/lib/security/pam_tally2.so): /usr/lib/security/pam_tally2.>
sddm-helper[754]: PAM adding faulty module: /usr/lib/security/pam_tally2.so
sddm-helper[754]: [PAM] Starting...
sddm-helper[754]: [PAM] Authenticating...
sddm-helper[754]: [PAM] authenticate: Module is unknown
sddm-helper[754]: [PAM] returning.
sddm[590]: Authentication error: "Module is unknown"
sddm-helper[754]: [PAM] Ended.
sddm[590]: Auth: sddm-helper exited with 1

If there is any other info I can provide let me know. I've never had to post on here for an issue I'm having so I am kind of new to this.

for me also same error occurred.

Downgrading to sddm 0.18.1 helped.

if anyone is looking for package:
http://hpc.ilri.cgiar.org/mirror/archlinux/pool/packages/sddm-0.18.1-3-x86_64.pkg.tar.zst

commands:
(login to tty2 ; shortcut:- ctrl+alt+F2)

wget http://hpc.ilri.cgiar.org/mirror/archlinux/pool/packages/sddm-0.18.1-3-x86_64.pkg.tar.zst

sudo pacman -U sddm-0.18.1-3-x86_64.pkg.tar.zst

reboot

happens, because pam_tally2.so missing in Archlinux (or i am blind) :-)

Can confirm that the autologin is broken with sddm 0.19.0 update.
'/usr/lib/security/pam_tally2.so' doesn't exist.

temporary working fix
   pam-faillock.diff (0.5 KiB)
Comment by AMM (amish) - Wednesday, 04 November 2020, 09:21 GMT
This commit in Arch removed pam-faillock.diff switching it back to pam_tally2.so and hence broke sddm-autologin

https://github.com/archlinux/svntogit-packages/commit/04149d41824526288bf1988e5399439d8db13c64#diff-3e341d2d9c67be01819b25b25d5e53ea3cdf3a38d28846cda85a195eb9b7203a

Here is original bug report which was fixed
https://bugs.archlinux.org/task/67372

And above commit broke it again by undoing it!
