Security page login problem

have created my application with security login,
…upload in server environment…working ok fine.
…when accessing my security page cant login with my original password.
… But when i go to the production design, i can see the password there is correct, and when testing the
security page work fine.
Some one can help out on this issue, really getting anoying.

Thanks in advance.

SC has a possible Bug is when you enter to app edir user, SC Chages the field password. That is because the browser autofill with old password.
I solved changing field password to NO Update in mode edit.

thanks alvagar,
i will try it, SC is good but sometime you need to waste with so many works around.
