Removing Facebook logins in Opera browser

How are extra logins formed? Everything is very simple, each user of social networks and forums has a lot of logins and passwords and sometimes he automatically enters them into the window of another portal. The browser remembers logins automatically and if you do not clear this field, a whole “elevator” of unnecessary logins can accumulate. Removing logins is also necessary from a security point of view, as sometimes in the login field you can mistakenly enter a password that will be saved in the browser along with one-word login. Naturally, I do not want to show the password to anyone and such an erroneous login-password needs to be deleted.
We hope that the material will be useful and save users time in search of a solution that is obvious at first glance.
