.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
service module implements counter-based and time-based one-time
|
||
|
|
passwords.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
service module recognizes the following options:
|
||
|
|
.Bl -tag -width ".Cm echo_pass"
|
||
|
|
.It Cm nokey = Ar fail | fake | ignore
|
||
|
|
Specifies how the module should behave when no key is available for
|
||
|
|
the user: either fail immediately, prompt for a code but fail anyway,
|
||
|
|
or let authentication proceed by other means.
|
||
|
|
\" .It Cm nouser = Ar fail | fake | ignore
|
||
|
|
\" Specifies how the module should behave when the user does not exist.
|
||
|
|
\" See
|
||
|
|
\" .Bm nokey
|
||
|
|
\" above.
|
||
|
|
\" .It Cm badkey = Ar fail | fake | ignore
|
||
|
|
\" Specifies how the module should behave when the user exists and has a
|
||
|
|
\" key, but the key could not be loaded (e.g. due to a syntax error in
|
||
|
|
\" the keyfile).
|
||
|
|
\" See
|
||
|
|
\" .Bm nokey
|
||
|
|
\" above.

|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
service module uses
|
||
|
|
.Xr pam_get_authtok 3
|
||
|
|
to prompt the user, and will therefore also be affected by the
|
||
|
|
standard options
|
