Identity Providers (IdPs) Explained: Types, Benefits, Examples

published on 21 June 2024

Identity Providers (IdPs) are systems that manage digital identities, ensuring secure access to online resources. Here's what you need to know:

  • IdPs create, store, and maintain user accounts
  • They verify user identities and grant access to apps and systems
  • IdPs offer single sign-on (SSO) for multiple resources
  • They improve security and simplify account management

Key types of IdPs:

  1. On-premises (e.g., Active Directory)
  2. Cloud-based (e.g., Okta, Azure AD)
  3. Social media (e.g., Google, Facebook)
  4. Blockchain-based (emerging technology)

Benefits of using IdPs:

  • Enhanced security through multi-factor authentication
  • Easier logins with SSO
  • Simplified account management
  • Scalability for growing businesses
  • Compliance with regulations like GDPR and HIPAA

Common IdP protocols:

Hosting Internal network Third-party cloud Social platforms
Best for Large enterprises Businesses of all sizes Consumer apps
Examples Active Directory, LDAP Okta, Azure AD, AWS IAM Google, Facebook, LinkedIn
Scalability Limited High Very high
Integration Complex Easier Simplest

IdPs are crucial for modern digital security and user experience, offering centralized identity management across multiple platforms and services.

How Identity Providers work

Main tasks of IdPs

Identity Providers (IdPs) do three main things:

  1. Handle login requests
  2. Check user identities
  3. 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:

  1. Authentication: Making sure users are who they say they are
  2. 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
Google Wide user base, easy integration
Facebook Popular choice for consumer apps
LinkedIn 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.

Aspect Description
Status Early stages of development
Potential Could change how we manage digital identities
Focus Improved security and privacy

In the next part, we'll look at the benefits of using Identity Providers.

Advantages of using Identity Providers

Identity Providers (IdPs) offer many benefits for both organizations and users. Here are the main advantages:

Better security

IdPs help keep information safe by:

Security Feature How it Helps
Multi-factor authentication Makes sure only the right people can access resources
Strong password rules Reduces the chance of easy-to-guess passwords
Account lockouts Stops repeated login attempts

These features lower the risk of data breaches and other security problems.

Easier logins

IdPs make logging in simpler:

  • Users only need one set of login details for many apps and services
  • No need to remember lots of usernames and passwords
  • Fewer password-related security issues

Simpler account management

IdPs help manage user accounts better:

Task How IdPs Help
Adding new users One place to set up accounts
Removing old users Quick to stop access when needed
Changing access rights Easy to update what users can do

This saves time and reduces mistakes in managing accounts.

Grows with your business

As your business gets bigger, IdPs can handle more users and services. This means you can focus on your work instead of worrying about managing logins.

Follows the rules

IdPs help businesses follow important rules like GDPR, HIPAA, and PCI-DSS. They do this by:

  • Keeping track of who can see what information
  • Making sure only the right people can access sensitive data
  • Providing proof that the business is following the rules

This helps businesses avoid fines and other problems from not following these rules.

Common Identity Provider protocols

SAML: What it is and how it's used

SAML

SAML (Security Assertion Markup Language) is a protocol that helps IdPs and Service Providers share login info. It lets users access many services with one login.

SAML Features Description
Format XML-based
Main use Single Sign-On (SSO)
Common in Big companies

OAuth: Allowing app access

OAuth

OAuth lets apps use parts of your accounts without knowing your password.

OAuth Aspects Details
Type Authorization tool
User benefit Share limited account access
Popular with Social media, mobile apps

OpenID Connect: Adding user identity to OAuth

OpenID Connect

OpenID Connect (OIDC) builds on OAuth by adding user identity checks.

OIDC Traits Explanation
Based on OAuth 2.0
Added feature User identity verification
Used for Logging into many apps at once

New protocols on the horizon

New login tools are being made to make things safer and easier:

New Protocol Purpose
JWT Quick, small way to check users
FIDO2 Login without passwords
WebAuthn Safer logins on websites

These new tools will change how we log in and keep our info safe online.

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
