how can I get the master password same as I have others like active and posting?

The master password is the seed phrase. That 24 words is the master password

ok. It's in different format so how can I get the one with same as other keys?

The seed password or master password (same here) is a derivative key, which means that for each unique master password you will have a set of unique owner, active, posting, memo keys. If you change ANYTHING on the password, ALL your keys change and vice versa too.

It worked and thanks for your help. Your help has helped me a lot on this platform
