What is the value of social login?
When designing login ability — it’s often easy to jump to the conclusion that we should include social login as alternative signup method. Whilst the research determines there are certain advantages to this, it is important to consider social login in the context of your product or brand.
For example, whilst Facebook login may be appropriate for a travel site that wishes users to be able to see their friends activity , it may not be inappropriate for a recruiting application aiming to connect highly skilled prospects to companies. In this case Facebook login may put off users that don’t wish their information to be shared within this context or could even act to dilute the respectability of the brand;
Nevertheless here is a compilation of the research for you to decide whether social login is appropriate ;
