How Identity Providers work
Main tasks of IdPs
Identity Providers (IdPs) do three main things:
- Handle login requests
- Check user identities
- Give access to services
IdPs in action: Step-by-step process
Here's how IdPs work:
| Step | Action |
|---|---|
| 1 | User tries to log in |
| 2 | Service sends user to IdP |
| 3 | IdP checks user details |
| 4 | IdP tells service if user is okay |
| 5 | Service lets user in |
IdPs in authentication and authorization
IdPs do two key jobs:
- Authentication: Making sure users are who they say they are
- Authorization: Deciding what users can access
IdPs use special rules (like SAML and OAuth) to share this info with services. This makes sure users can only see what they're allowed to see.
Different types of Identity Providers
Identity Providers (IdPs) come in several forms. Each type meets specific needs. Here's a breakdown of the main IdP types:
On-premises IdPs
These are identity management systems that run within an organization's own network. They handle user identities and access to internal resources.
| Type | Description | Examples |
|---|---|---|
| Active Directory | Microsoft's system for Windows networks | Manages user logins, access control |
| LDAP | Protocol for directory services over IP | Used for accessing and maintaining user data |
Cloud-based IdPs for businesses
These are hosted solutions offered by third-party providers. They manage user identities for both cloud and on-site resources.
| Provider | Key Features |
|---|---|
| Okta | Manages user authentication across various apps |
| Azure AD | Microsoft's cloud-based identity service |
| AWS IAM | Amazon's identity and access management tool |
Social media as IdPs
These use social network accounts for user login. They make it easier for users to access multiple services with one set of credentials.
| Social IdP | Benefits |
|---|---|
| Wide user base, easy integration | |
| Popular choice for consumer apps | |
| Useful for professional services |
Blockchain-based IdPs
These are new systems that use blockchain for decentralized identity management. They give users more control over their digital identities.

Ideas linked to Identity Providers
Single Sign-On (SSO) explained
Single Sign-On (SSO) lets users access many apps with one login. It:
- Needs only one username and password
- Makes logging in easier
- Cuts down on forgotten passwords
Example: When you log into Google, you can use Gmail, YouTube, and Google Drive without extra logins.
What is federated identity?
Federated identity lets users access many apps across different groups with one login. It works like this:
| Step | Action |
|---|---|
| 1 | User logs in to their main account |
| 2 | Other apps trust this login |
| 3 | User gets into other apps without new logins |
Real-world use: Using Facebook to log into other websites.
Multi-Factor Authentication (MFA) basics
MFA adds extra steps to logging in, making it harder for others to break in. It uses:
| Factor | Example |
|---|---|
| Something you know | Password or PIN |
| Something you have | Phone or security token |
| Something you are | Fingerprint or face scan |
