Social media authentication refers to the use of social networks to identify or validate the source of information. If you are still unsure about the source's reliability, you can use:
- Your own social network (Twitter, Facebook, LinkedIn) to find out if anyone in your network knows about the source; or
- The broader online community to find out the reliability of the source. For example, you can Tweet, “Does anyone know about this person/account?”
- Ask your offline network if they know the source.
