What is Single Sign-On (SSO)?
Single Sign-On (SSO) is a way for people to log into many different apps or websites using just one username and password. This makes logging in easier and safer, as users don't have to remember lots of different passwords.
How it Works
SSO works by linking together an identity provider (the service where you enter your single username and password) with the services you want to use:
- When you want to use a service, you're first sent over to the identity provider.
- You log in there with your single set of credentials.
- The identity provider checks your details and, if they're correct, creates a special secure message (a token) that proves who you are.
- You take this token back to the service you wanted to use, which checks it's correct and lets you in.
- You're now logged in and can use the service without having to enter another username and password.
Why It's Good for Businesses
For companies, SSO is great because:
- It's more secure: It helps ensure that passwords are strong and used properly.
- It makes for a better user experience: Employees can quickly access all the tools they need without getting bogged down by passwords.
- It simplifies things for the IT team: They can manage access to services from one place, making things like adding new employees or changing permissions easier.
Examples with Microsoft Azure
Microsoft Azure lets businesses set up SSO easily:
- With apps like Salesforce: You register the app in Azure, set up the right settings, and assign users or groups.
- For your own apps: You can use Azure's tools to connect your app to Azure, so users can log in using SSO.
In both cases, Azure acts as the identity provider, making it easier for users to access different services securely with just one set of login details.
