Recently, I noticed that when using tty to login to my computer, there was a delay (around 20 seconds) between the time I enter my username and the time I'm getting asked for my password. Where can it come from ?
I don't have such delay when using su username or ssh username@localhost and my password is asked right away.
I'm using Arch Linux with kernel 5.14.16.
EDIT
Finally found the problem. There was a broken module in PAM (fingerprint auth) which needed to timeout before asking a password. Just disabled the module.
