In the Opera browser versions 7 and up, the wand is the password manager. One can choose whether the wand should save the password for a page or for a whole server, and next time one enters the site, the username/password fields should already filled in. If they are not, or if it is a different page on the same site, clicking the wand symbol on the main bar should both fill in the fields and submit the information. Passwords and usernames are scrambled before they are saved. The wand can of course itself be protected by password or simply disabled (under preferences > security), for example if the browser is regularly accessed by more than one user.
