The Complete 2023 Guide to User Authentication Platforms

Hi there,

As an experienced cybersecurity pro, you’re well aware of how vital rock-solid authentication has become.

With over 50% of breaches directly involving compromised credentials, relying solely on basic passwords is no longer prudent.

That’s why in this comprehensive guide, we’ll be exploring the top 18 identity and access management platforms available for implementing advanced authentication mechanisms like:

• Multi-factor authentication (MFA)
• Single sign-on (SSO)
• Social login
• Passwordless
• Adaptive policies

I’ll share insights from real customer use cases, comparison charts of capabilities across products, as well as recommendations from leading authentication experts.

Let‘s get started!

Why Layer External Authentication Services

“Never build your own crypto…or identity systems for that matter!”

This is what Rahul Vaidya, Co-founder of enterprise SSO platform Myki firmly advocates.

While it may be tempting for engineering teams to build in-house systems, specialized third-party authentication services offer compelling advantages:

Accelerated Speed-to-Launch

Get to market faster by leveraging provider SDKs, widgets and APIs instead of custom development.

- Office 365 
- G Suite  
- Salesforce 
- Slack
- Custom Web Apps

Advanced Security Capabilities

Continuously stay updated on the latest identity standards and defense strategies.

Auth0 maintains compliance and applies latest practices: 

- OAuth 2.0 OpenID Connect
- FIDO2 / WebAuthn passwordless  
- Breached password detection  
- Anomaly monitoring using adaptive ML

Regulatory Compliance

Essential for regulated sectors like healthcare, finance. Services conduct compliance audits.

Microsoft Entra Permissions Management maintains:

- HIPAA
- GDPR
- CCPA
- IRS 1075

And as Gartner states, through 2024 implementing IAM from a specialist vendor will directly accelerate your application delivery lifecycle versus in-house builds.

Now let’s explore top options across both self-hosted open source to fully managed SaaS offerings.

Self-Hosted Open Source User Authentication

If leveraging community-driven open source software aligns best to your identity strategy, two compelling platforms lead the pack.

Both give teams complete control through on-premise or cloud hosting while benefiting from OSS community enhancements.

Keycloak: Feature-Rich Platform and SSO

Keycloak offers an adaptable authentication, authorization and SSO server for segmented access control.

It enables single sign-on to all applications so users avoid re-authenticating repeatedly. Social login, user federation and custom consents are directly built-in.

Rich standards support including OIDC and OAuth 2.0 makes integration with existing tools a breeze while staying interoperable.

For a self-managed system with abundant controls, Keycloak shines for:

Use Cases

• Financial sites needing segmented user access controls
• Platforms with existing user stores to consolidate
• Teams wanting standards OIDC/OAuth 2.0 based SSO

Integrations

• Social login (Facebook, Google etc.)
• External user stores via LDAP
• Allows bringing your own database

Authenticators

• Custom password policies
• TOTP
• WebAuthn + FIDO2
• Backup codes

ORY: Headless Authentication and UX Flexibility

ORY delivers an open-source identity server focused on UX extensibility and headless architectures.

It acts as centralized authentication middleware for signing, TOTP MFA, profile management. You retain full frontend code control without restrictions to integrate react, vue, angular UIs.

ORY advantages for teams wanting UI customization without authentication overhead:

Use Cases

• Applications with specialized self-developed frontends
• Startups not wanting vendor/platform UX restrictions
• Bootstrapping identity capabilities before projected scaling

Protocols

• OAuth 2.0
• OpenID Connect
• SupportsJWT, methods like lookup secrets

Features

• Authentication ORY ecosystem
• Granular identity schema control
• Password breach detection
• Brute force attack prevention

If either self-hosted platforms fit your resources and security policy – they deliver robust capabilities minus the operational overhead of SaaS expenses.

Next let’s explore leading managed authentication service offerings.

SaaS User Authentication Platforms

For most modern tech stacks, opting for a specialized authentication-as-a-service makes operational and financial sense. Top providers offer generous free tiers to bootstrap projects before scaled usage .

Let‘s analyze five compelling managed SaaS choices:

Supabase: Open-Source Inspired Platform and Firebase Alternative

Supabase models itself as an open-source alternative vs closed sourced Firebase. Combining PostgreSQL, real-time APIs with PostgREST makes integration familiar for JS/TS devs.

It allows passwordless email magic links, social logins along user management and authorization rules. Supabase suits developers wanting an OSS-inspired backend with authentication functionality.

Use Cases

• Startups on tight budgets needing essential identity features
• Applications already leveraging PostgreSQL as primary datastore
• Teams lacking Ops resources for hosting infrastructure

Authenticators

• Email magic links
• OAuth via Google, GitHub etc.
• Database customizable password policies

Pricing

• Free tier targeting smaller workloads
• Standard and Pro tiers with incremental usage pricing

Firebase Authentication by Google

Google‘s Firebase provides out-of-the-box auth for signing in users via email, phone numbers and federated identity providers like Facebook, Twitter, GitHub etc.

It offers native UI libraries for Android, iOS, web getting started quickly. Underlying infrastructure is fully managed by Google.

Use Cases

• Startups needing essential standards-based authentication
• Developers already bought into Firebase stack
• Teams lacking resources for hosting infrastructure

Protocols

• Email / Password
• Phone / SMS
• Popular OAuth providers

Pricing

• Free tier
• Firebase Auth usage at $1.00 per MAU

Auth0: Feature-Rich Authentication and Authorization

Auth0 is one of most ubiquitous identity platforms used by enterprises and smaller companies alike.

Beyond robust authentication support via social providers, LDAP, SAML – it offers sophisticated authorization policy engines for fine-grained access controls and administration.

Use Cases

• Companies needing enterprise grade identity management
• Teams with complex organizational structures and external partners
• Custom admin consoles required for hierarchical org structures

Features

• Standards: SAML, WS-Fed, OAuth 2.0, OIDC, LDAP

For stacks needing CIAM capabilities, ForgeRock provides robust protocol conformity alongside standards IAM features.

While we only covered 8 recommendations in detail – analyst projections show the overall identity-as-a-service category accelerating at an 18% CAGR towards 2025 as threats get more sophisticated.

Expert Authentication Strategies and Considerations

“Too often companies focus exclusively on the authentication event, when managing identity lifecycles holds equal importance.”

This key insight comes from Justin Richer, VP of Product at access management leaders ForgeRock.

He elaborates on striking balance between elements like:

• Initial access policy decisions during onboarding
• Provisioning authorizations as roles evolve inside organizations
• Access revocation when offboarding employees

“Enterprises must look at full lifecycle management not just point access transactions. Specialized IAM platforms address these needs holistically”

Additional food-for-thought from other authentication experts:

• Nishant Kaushik, CTO at Uniken advocates for a Authenticate-Encrypt-Connect model for preserving data security not just access control as threats become more sophisticated.

• Rick Cranston, VP at Auth0 stresses increased adoption of passwordless using factors like WebAuthn which eliminates human generated passwords responsible for majority of breaches.

• Dominick Baier, Co-founder of IdentityServer suggests progressive rollouts using hybrid modes during migrations to modern authentication improving reliability.

While technical elements are crucial, forging an internal culture valuing security and vigilance proves equally vital.

With these recommendations and insights, I‘m confident you’re better equipped for evaluating and onboarding world-class authentication safeguarding your digital assets.

Wishing you resilient user experiences!
