First you need to regenerate your password.
Then you must change your password to the POSTING password. With this password you can only post things to your account. So this may allow you to save your master password to make SBD transfers.

To change this, go to your wallet>persmissions>click on "show private key" next to posting keyword (It is necessary that you click there to show the password you will use) Copy it and then change your password :) and Done.

Remember keep it safe both! Because they are important as well.
From now on, anyone who can access your account can only post because they will not have the master password.

Hope this be helpful for you, be careful!

Sorry if my english is not very good, but my friends explained me this and I think you need it and all the steemians who read this comment :)
