Does SELECT count(*) FROM Authentication_Detail WHERE UserName = @username AND password = @password return 1? i.e. Are you sure the record exists in the database?

I trust you are hashing your passwords properly and not saving them as clear text.

I have tested it and works fine

CREATE PROCEDURE [dbo].[Proc_Verify_Password]
    @username VARCHAR(20),
    @password varchar(20)
AS
BEGIN
 
 SET NOCOUNT ON
 
SELECT  count(*) FROM Authentication_Detail 
WHERE RTRIM(LTRIM([UserName])) = RTRIM(LTRIM(@username)) 
AND RTRIM(LTRIM([Password])) = RTRIM(LTRIM(@password))

END
