OpenID

OpenID is an online authentication protocol that allows users to log into multiple websites using a single account from an OpenID provider. Instead of creating different usernames and passwords for each site, you can sign in with one OpenID account, making online interactions simpler and more secure. For example, if you have an OpenID from a provider like Google, you can use it to access various services without needing individual credentials for each one. This streamlines the login process and reduces the risk of forgetting passwords or falling victim to phishing attacks.
