Social login/signup or third-party login/signup is a simplified method to log in or join an application. Instead of creating a new account, it uses existing login information from a social media profile on Google, Twitter, Facebook, or other networks. Users prefer social logins and are more likely to register on an app if it offers this feature.

This technique has other advantages too:

• Reduced interaction cost: Instead of typing their email or phone number and creating a password, users just need to press one button with the desired social network provider.
• You don't need to verify emails: Users tend to provide fake emails when registering on apps. Social login protects your app from unverified data because social network providers verify users' email addresses. Additionally, the providers handle the password recovery process.^[1]
