+## Prerequisite
+
+Read [this](https://twitter.com/thomashabets/status/1133780752582217728), have a little chuckle to yourself.
+
+After that: no seriously really do confirm it. Most of the reported issues with TOTP follow that pattern.
+
+## PAM config
+
+E.g. `/etc/pam.d/ssh`, or `common-auth` if it uses that.
+
+## SSH config (or equivalent if not using SSH)
+
+`/etc/ssh/sshd_config`
+
+## Enable `debug` on the module, and paste what's logged
+
+Maybe from `/var/log/auth.log`.
