    WHERE [Pass] = [Partners].[Pass]

but im getting this error:

Msg 170, Level 15, State 1, Line 3 Line 3: Incorrect syntax near 'Pass'.

Answer 1

UPDATE P
SET    [Pass] = U.[Pass]
FROM   [databasename].[dbo].[Partners] P
       JOIN [databasename].[dbo].[User] U
           ON U.[Code] = P.[Code]

Answer 2

You need to learn some basic SQL Server syntax:

UPDATE P
    SET  P.Pass = U.Pass
    FROM       [nima08].[dbo].[Partners] P
    INNER JOIN [nima08].[dbo].[User]     U ON P.Code = U.Code

UPDATE U
    SET   U.Pass = P.Pass
    FROM       [nima08].[dbo].[User]     U
    INNER JOIN [nima08].[dbo].[Partners] P ON U.Pass = P.Pass
