because here

where user_Id=@advId

you are only passing single id not multiple id

how to pass multiple id

Solution 2

You have to use while loop within the Trigger to update or insert multiple records

SQL

ALTER TRIGGER [dbo].[tri_memberLoginUpdate]
ON [dbo].[tbl_advisor_registration]
FOR  UPDATE
AS

    UPDATE T
    SET    t.USerName = i.advisor_username, t.Password =  = i.advisor_password
    FROM   tbl_login t
           INNER JOIN INSERTED i
                ON  i.advisor_id = t.User_id
                    AND t.Status = 2

i don't think there is a loop needed hope this solves your problem
