In general, when signing into a website to check your personal account, you need to use a unique user name/password. However, for years other sign in options have included to sign in with your Facebook, Google, LinkedIn, etc... account. This other option is called a social login.
According to VentureBeat, Google is catching up to Facebook in market share regarding social logins. Facebook has 43% of the market while Google has 40%. Social logins have proliferated because companies want to track you for monetization purposes.
I don't use social logins and I don't recommend anyone who values their privacy to utilize social logins. Facebook and Google are advertising companies that sell your personal data points for profit. Facebook is selling your personal information to data brokers and Google has paid tens of millions of dollars in fines for intentionally misleading users about its privacy practices.
There is no reason to sign into non-Facebook/non-Google websites with a Facebook or Google social login. These companies may send your personal information to data brokers, insurance companies, the police, employers, etc...
Will 2015 be the year that users wise up and avoid social logins?
