Passkeys, physical tokens, and protected admin access

Secure Access for Web Applications

Modern Passkey Auth for Legacy Systems

Authmosphere adds a secure access layer in front of WordPress admin panels, legacy portals, and existing web applications. Authenticate users with passkeys, QR/NFC-linked tokens, and stronger access controls while leaving the underlying app in place.

A secure access layer for your web applications

Authmosphere focuses on protecting web application access without forcing you to rebuild the application itself.

Protected Admin Access

Move sensitive login surfaces like WordPress admin or legacy portals behind Authmosphere without affecting the public-facing site.

Passkeys + Physical Tokens

Support passkeys, QR/NFC-linked access flows, and fallback authentication methods for environments that need more than passwords.

Flexible 2FA Options

Add SMS, Email, or Authenticator app-based 2FA as optional layers. Configure per-client based on their security needs and user preferences.

Reverse Proxy Gateway

Users authenticate through Authmosphere and then access the protected application through a controlled proxy layer.

Universal Web App Compatibility

Protect any web-based internal system—WordPress, Joomla, open source platforms, custom-coded projects, or legacy portals.

Flexible Deployment

Use shared hosting, VPS, dedicated servers, AWS, or self-hosted infrastructure depending on the client’s environment and requirements.

Built for real-world application access problems

Authmosphere is especially useful where the application cannot easily be rebuilt, replaced, or integrated with a modern identity system.

Legacy CRM Access

Protect older CRM or client portals with stronger authentication before the app is ever reached.

Vendor & Client Portals

Add a modern access layer around externally exposed dashboards and partner-facing web applications.

WordPress Admin

Keep the public site public while moving `/wp-admin` and `/wp-login.php` behind Authmosphere.

Custom Admin Surfaces

Use a protected host and proxy model to secure admin routes without rewriting legacy code.

How it works

Authmosphere adds a controlled authentication step in front of the target app, then proxies access after verification.

1

Connect

Map a protected host or integration to the target application or admin surface you want to secure.

2

Authenticate

Require passkeys, QR/NFC-linked tokens, and other configured methods before allowing access to the application.

3

Proxy

Once verified, Authmosphere proxies the protected application while leaving the underlying app and public site behavior intact.

Deployment modes that match the hosting reality

Not every environment offers the same level of control. Authmosphere can be adapted to fit the customer’s infrastructure.

Shared Hosting

Best for WordPress and legacy web apps where the customer has limited server access.

  • Plugin + Authmosphere gateway
  • Optional edge hardening where appropriate
  • Public site remains untouched

VPS / Dedicated Server

Adds stronger server-level controls for customers with more robust infrastructure.

  • Protected host + reverse proxy model
  • Server restrictions for admin routes
  • Improved origin hardening

Self-Hosted / Managed Infrastructure

Suitable for clients who want stronger control, isolated deployment, or managed hosting by your team.

  • Deploy within client or managed environment
  • Broader control over proxy and access policies
  • Best fit for sensitive or regulated environments

Security that meets the application where it is

Authmosphere is designed for practical deployments: from shared-hosting WordPress admin protection to stronger, more isolated gateway deployments on customer-managed infrastructure.

Passkey-ready access flows

Support stronger, phishing-resistant authentication where supported.

Physical-token-friendly model

QR and NFC-linked access flows can be layered into the gateway experience.

Application-preserving approach

Protect the app without requiring a rebuild, replacement, or deep code integration.

SaaS or self-hosted path

Offer hosted access protection or deploy a self-hosted model for sensitive clients.

Environment-dependent

Stronger origin isolation is available where the hosting environment allows it. Shared hosting deployments prioritize practical admin protection and reduced attack surface.
