I just finished logging into eight different Twitter accounts (all of which had 2-factor of one kind or another on them, so were fairly safe anyway) and changing all their passwords. Including one account I created back in 2011 or something and have literally never got round to using. I'm not sure I can even remember what it was going to be for, now, although I'm sure I had a project in mind for the account name. I know, I should probably just delete them all, but I hate deleting stuff, probably for the same reason my living space is jammed full of stuff I haven't used yet (but absolutely definitely will someday). At least with fresh passwords they should be safe to leave alone for now.
