+# Time-based One-Time Passwords (TOTP)
+#
+# Defined in RFC 6238, and used in Google Authenticator.
+#
+# This module can only be used in the "authenticate" section.
+#
+# The Base32-encoded secret should be placed into:
+#
+# &control:TOTP-Secret
+#
+# The TOTP password entered by the user should be placed into:
+#
+# &request:TOTP-Password
+#
+# The module will return "ok" if the passwords match, and "fail"
+# if the passwords do not match.
+#
+# Note that this module will NOT interact with Google. The module is
+# intended to be used where the local administrator knows the TOTP
+# secret key, and user has an authenticator app on their phone.
+#
+# Note also that while you can use the Google "chart" APIs to
+# generate a QR code, doing this will give the secret to Google!
+#
+# Administrators should instead install a tool such as "qrcode"
+#
+# https://linux.die.net/man/1/qrencode
+#
+# and then run that locally to get an image.
+#
+#
+# The module takes no configuration items.
