teradata and password expired!

...
UserName = "user1"
userpwd = "passw1"

Set CONN = New ADODB.Connection
CONN.CommandTimeout = 0
CONN.ConnectionString = "Data Source=Teradata Produzione;Database=DBH;UID="& UserName & ";PWD="& userpwd
CONN.Open
...

I use this code to connect a Tredata database.

Prob! when the password expire in the vb project appear a windows popup to tell me to change the expired password...!

Is possible via code when the pasword expire automaticlly use a new password and store for next use?

I have gogling and in a post i see to set int string connection a new PWD similar:

CONN.ConnectionString = "Data Source=Teradata Produzione;Database=DBH;UID="& UserName & ";PWD="& userpwd;PWD1="& userpwd1
And when the old pasword expire the code use the new userpwd1

is this correct?
