I migrated from LastPass and am in the process of changing all of my passwords. However, I also had numerous secure notes. Those notes migrated to 1Password. But are they secure here? If my master password at LastPass was hacked, it would seem that the secure notes over there are at risk. But now here at 1PASSWORD, I can't "change" them, as the info stays the same. E.g., a note that has a bank account routing number can't be changed like a password can.
