In plain words
Which Login? is a browser extension that tracks which social login method users previously used on websites, helping them avoid accidentally creating duplicate accounts. The tool stores information about whether a user signed in via Google, Facebook, Twitter, or other social platforms, then displays this reminder when returning to a site. It addresses the common problem of forgetting which authentication method was used, saving users from the friction of password resets or account duplication.
