Setting
a
Password
You
can
create
an
encrypted
password
for
the
logger
that
will
be
required
if
another
phone
or
tablet
attempts
to
connect
to
it.
This
is
recommended
to
ensure
that
a
deployed
logger
is
not
mistakenly
stopped
or
purposely
altered
by
others.
This
password
uses
a
proprietary
encryption
algorithm
that
changes
with
every
connection.
To
set
a
password:
1.
Tap
the
Devices
icon
(in
HOBOmobile,
tap
Loggers
at
the
top
of
the
screen).
Tap
the
logger
in
the
app
to
connect
to
it.
2.
Tap
Logger
Password
in
HOBOmobile
or
tap
and
then
in
HOBOconnect.
3.
Type
a
password
and
then
tap
Save
or
Set.
Only
the
phone
or
tablet
used
to
set
the
password
can
then
connect
to
the
logger
without
entering
a
password;
all
other
mobile
devices
will
be
required
to
enter
the
password.
For
example,
if
you
set
the
password
for
the
logger
with
your
tablet
and
then
try
to
connect
to
the
device
later
with
your
phone,
you
will
be
required
to
enter
the
password
on
the
phone
but
not
with
your
tablet.
Similarly,
if
others
attempt
to
connect
to
the
logger
with
different
devices,
then
they
would
also
be
required
to
enter
the
password.
To
reset
a
password,
Press
both
the
Start/Stop
button
and
the
Clear/Next
button
simultaneously
for
3
seconds
to
reset
a
logger
password,
or
connect
to
the
logger
and
then
tap
Set
Logger
Passkey
and
select
