The short version

  • Each has a real cost: Auth0 free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that; Microsoft Edge outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.
  • They diverge on capability: Auth0 covers Universal login, Microsoft Edge covers Internet Explorer mode.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

Microsoft Edge

  • Outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.
  • It is Chromium downstream, so Manifest V3 applies exactly as it does in Chrome; full-strength blocking extensions cannot run, and Microsoft's add-ons store adds a second review process rather than a workaround.
  • Almost all of its advantage is conditional on Microsoft 365 and Entra ID; a Google Workspace or AWS-centred organisation gets Chromium plus Microsoft's promotional surfaces and none of the Purview, Intune or conditional access value.
  • Consumer-facing features including Copilot, the Discover pane, shopping notifications and sidebar apps default to on and reappear after feature updates, so suppressing them requires a maintained policy set rather than a one-off configuration.
  • IE mode is a bridge with a maintenance owner attached: the Enterprise Mode Site List must be curated by somebody, and MSHTML receives security fixes but no new capability, so an application parked there gains nothing and its eventual rewrite is only deferred.
  • By default browsing data feeds Microsoft services for Copilot, Discover and shopping features, which in a regulated environment turns the deployment into a policy exercise before it can be approved.

Answered from the vendors’ own pages

Auth0: How much does Auth0 cost?

Auth0 has a Free tier for up to 25,000 monthly active users (MAUs). Paid plans start at $35/month (Essentials B2C) and scale to $240/month (Professional B2C) and higher for Enterprise. Pricing scales with MAU usage.

Microsoft Edge: Can I uninstall Edge from Windows?

In the European Economic Area, yes, because the Digital Markets Act requires it. Elsewhere you cannot, and several Windows components will continue to open it regardless of your default browser.

Auth0: Does Auth0 include Multi-Factor Authentication?

No. MFA, RBAC (Role-Based Access Control), and premium support are not included in the free tier and require upgrading to paid Essentials plans or higher.

Source
Microsoft Edge: How long will Internet Explorer mode be supported?

Microsoft has committed to supporting IE mode in Edge through at least 2029. It is a migration window rather than a permanent home, since the underlying MSHTML engine gets security fixes but no new capability.

Auth0: Is Auth0 independent or part of a larger company?

Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.

Source
Microsoft Edge: Do Chrome extensions work?

Yes. Edge installs extensions from the Chrome Web Store as well as its own store. Manifest V3 restrictions apply identically, so extensions that Chrome no longer supports do not work here either.

Auth0: Who should use Auth0 vs Okta?

Auth0 is developer-focused and serves customer identity use cases (B2C). Okta serves workforce identity (B2B) and has broader enterprise features. Auth0 now serves both markets post-acquisition but maintains its developer-friendly positioning.

Source
Microsoft Edge: Is it worth deploying if we are not a Microsoft 365 organisation?

Usually not for the management features, which depend on Entra ID, Intune and Purview. Without that stack it is Chromium with a different interface and additional Microsoft promotion.

Microsoft Edge: Does it run on Linux?

Yes, there are official Linux builds. Some Windows-specific features, including IE mode, are not available there.
