Web of Trust is a system that helps people decide who to trust online. People recommend websites, apps and people they trust, and give each one a rating on how trustworthy they are. This helps other people know who is safe to trust online, since lots of information online can be fake or dangerous. Web of Trust collects all of these ratings and ranks websites by how trustworthy they are. That way, people can make sure they don’t trust the bad websites or people.
