Hi, I would like to know where explicit login is located in PI SMT? I know that there is 3 methods to log on : Trust, Windows security and explicit login. I have never use it and I know it the least secure authentication. Thank you,

In SMT under "Identities, Users, & Groups" they show up as "PI Users". They are generally less secure as if you have the right password you can bypass security over other forms of authentication that can be restricted from the server side.
