01 · What you get

What a Auth0 integration gives you.

Secure unified login across channels

Customers and trade users log in once via Auth0 and access storefront, trade portal and account features without re-authenticating. Password resets and MFA policies are managed centrally.

Trade account permissions enforced consistently

Buyer groups mapped in Auth0 automatically control purchasing limits, catalogue visibility and pricing tiers in the commerce platform. Changes to group membership take effect immediately.

No orphaned or duplicate customer accounts

Account linking at first login matches Auth0 identities to existing commerce customers by email or ID. Subsequent logins restore the correct account context and order history.

Compliance and access control audited

Auth0 logs all login, group change and permission events. iWeb configures retention, alerting and reporting so compliance and security teams can audit access for sensitive customer segments.

Headcount and access costs aligned

Automatic deprovisioning removes inactive users from Auth0 and revokes commerce access when accounts are closed. No orphaned identities or suspended subscriptions.

02 · When it's worth it

Where a Auth0 integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Unified login across ecommerce storefront and trade portal
Trade account permissions mapped to buyer roles and purchasing limits
Customer account linking between Auth0 identity and commerce customer records
Automatic user provisioning and deprovisioning for staff and portal users
Session and MFA policy enforcement for high-value customer accounts
SAML and OAuth 2.0 federation for corporate and B2B buyers
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

No native commerce customer account sync

Auth0 does not automatically map users to commerce customers by email or ID. Manual matching rules or custom extension logic are needed to link Auth0 identities to existing customer records at first login.

Trade account permissions not built-in

Auth0 manages groups and roles generically. Mapping those groups to commerce-specific buying roles, pricing tiers, catalogue restrictions and purchasing limits requires custom configuration and middleware logic.

Session and logout synchronization

Logging out of the commerce platform does not automatically revoke Auth0 sessions. Both systems must be coordinated via token revocation or session store sync to prevent orphaned sessions.

Real-time account closure propagation

Auth0 has no native webhook for commerce account closures. Deprovisioning must be triggered via API calls from the commerce platform or an integration middleware when an account is cancelled.

No native B2B corporate account hierarchy

Auth0 supports group membership but not nested hierarchies or corporate org structures. Buyer-specific contract pricing, cost-centre rules or multi-level approval workflows must be stored and enforced outside Auth0.

04 · The real work

Login and permission gaps often hide until accounts are closed or groups change; testing account linking accuracy and deprovisioning latency before launch prevents silent access failures and compliance drift.

05 · Where it sits

Where this integration sits in your estate.

Auth0 holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

Commerce platform agnostic. Connect Auth0 across your entire technology stack.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

→Into COMMERCE
←From COMMERCE
↔BOTH WAYS
Authentication and session tokens: Auth0 validates login credentials and returns JWT or session tokens to the storefront
The commerce platform uses the token to identify the customer and restore their basket, account and permissions for the session.
User provisioning and group membership: New users are created in Auth0 and synced to the commerce platform with role and group data
Group changes in Auth0 propagate to commerce customer records to control purchasing permissions, pricing tiers and catalogue visibility.
Account linking on first login: When a customer logs in via Auth0 for the first time, the integration matches their Auth0 identity to an existing commerce customer record by email or external ID
Subsequent logins restore the full customer account context.
Deprovisioning on account closure: When a customer or trade account is closed in the commerce platform or ERP, the integration disables the corresponding Auth0 user or revokes active sessions to prevent further access.
MFA and policy enforcement: Auth0 policy rules (MFA requirement, password reset frequency, session timeout) are evaluated at login time
The commerce platform receives policy metadata in the token to enforce additional controls for sensitive customer segments.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    Account linking design and validation

    iWeb writes the matching logic that links Auth0 identities to commerce customers at first login by email, external ID or custom attribute. We test matching accuracy and handle edge cases like duplicate emails.

  2. 02
    Trade account permission mapping

    iWeb configures Auth0 groups and roles to map to commerce buying permissions, catalogue restrictions, pricing tiers and approval workflows. Changes to group membership sync to the storefront in real time.

  3. 03
    Session state and logout coordination

    iWeb manages token validation, session storage and logout synchronization between Auth0 and the commerce platform. We define how token expiry, revocation and re-authentication work at scale.

  4. 04
    Provisioning and deprovisioning automation

    iWeb builds API-driven workflows to create Auth0 users from commerce customer records and disable users when accounts are closed in the commerce platform or ERP. We handle batch and event-driven provisioning.

  5. 05
    Monitoring, observability and exception handling

    iWeb configures alerting for authentication failures, permission drift, session timeouts and failed deprovisioning. We build dashboards to track login volume, MFA adoption and access revocation latency.

09 · Ownership

Who owns what.

The single most important table in any integration. One system owns each field; everything else reads it.

Data

10 · Experienced integrator

Built this before

iWeb has integrated Auth0 into multiple commerce estates where customer and trade account access needed to be unified and permissions managed centrally. We understand how Auth0 sits between your login layer, ERP, trade portal and staff systems.

Designed account linking rules that match Auth0 identities to commerce customers by email, ID or custom attribute without creating duplicates or orphaning accounts
Mapped Auth0 groups to commerce buying permissions, catalogue restrictions, pricing tiers and approval workflows for trade segments
Built provisioning and deprovisioning workflows triggered by HR systems, customer closures and ERP events to keep Auth0 user directories in sync at scale
Configured session state, token revocation and logout coordination across Auth0, storefronts and trade portals to prevent orphaned sessions and account takeover
Set up monitoring, alerting and audit logging for authentication failures, permission drift, failed deprovisioning and policy violations
11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Email-based account linking creates zero duplicate customer records across 100 test logins with varied email formats and casing.
Auth0 deprovisioning disables user login within 5 minutes of account closure in the commerce platform; active sessions are revoked immediately.
Group changes (promotion from customer to trade tier) take effect on next login and reflect in commerce catalogue permissions and pricing within 60 seconds.
MFA enforcement for trade accounts blocks checkout without a second factor; fallback to password-only fails gracefully and alerts operations.
Session logout on the storefront revokes Auth0 tokens and prevents API calls with the revoked token within 10 seconds.
SAML and OAuth federation logins (e.g. from corporate Active Directory) map directory attributes to Auth0 groups and sync permissions without manual step.
Failed login monitoring captures password-reset loops, locked accounts and deprovisioning lag; alerting triggers within 2 minutes of first failure.
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Account linking failure on first login

If the email or ID match rule is misconfigured or customer records lack the expected key attribute, new Auth0 users fail to link and cannot access orders or account history. They see a blank customer record instead.

Group-to-permission drift over time

Auth0 group membership changes but the commerce platform or pricing system has not been updated with the new group. Buyers see outdated catalogue restrictions or pricing tiers until a manual sync runs.

Orphaned sessions after logout

A user logs out of the storefront but Auth0 tokens are still valid. If a token is compromised, the attacker can still make API calls on behalf of the customer until the token expires naturally.

Deprovisioning lag when accounts are closed

An account is closed in the commerce platform or ERP but Auth0 is not notified immediately. The user can still log in and place orders until a daily or manual deprovisioning job runs.

MFA policy enforcement inconsistency

Auth0 requires MFA for a customer segment but the commerce platform does not understand or enforce the policy. High-risk customers bypass MFA at checkout or the platform falls back to password-only authentication.

B2B corporate account hierarchy not mapped

Auth0 has no native hierarchy for corporate buyers with multiple users and cost-centre rules. iWeb must build custom logic to store and enforce the hierarchy, or approvals and purchasing limits are not applied.

14 · Questions

Common questions about Auth0 integrations.

How does account linking work when a customer logs in for the first time?

Auth0 returns the user's email or external ID. iWeb configures a matching rule that looks up the commerce customer record by email or ID. If a match is found, the Auth0 identity is linked; if no match exists, a new customer record can be created or the user is prompted to complete signup. The rule runs at every login to handle cases where the customer's email has been updated.

Can we enforce MFA for high-value trade accounts only?

Yes. Auth0 can be configured with rules that trigger MFA based on user group, IP range or risk score. iWeb configures the rule to require MFA for trade customers or buyers above a spending threshold. The commerce platform receives MFA status in the token and can enforce additional checks at checkout if needed.

How are trade account permissions (groups, pricing tiers, catalogue restrictions) kept in sync?

Auth0 groups are created for each trade segment (e.g. 'wholesale_tier_1', 'trade_b2b'). When a user logs in, their group membership is included in the token. iWeb configures the commerce platform to read the groups and apply the corresponding permissions (pricing rules, catalogue visibility, purchasing limits). Changes to group membership in Auth0 take effect on the next login.

What happens when we close a customer account in the commerce platform?

iWeb sets up an event listener or API hook on account closure. When triggered, it disables the corresponding Auth0 user and revokes active sessions. The customer cannot log in again, and if they try, they receive a 'user disabled' error. If the Auth0 deprovisioning is delayed, we configure a fallback check in the commerce platform to confirm the account is still active before allowing access.

How do we prevent orphaned sessions after logout?

iWeb configures session state to be revoked in Auth0 when the user clicks 'log out' on the storefront. If using JWT tokens, we store a token revocation list (blacklist) in the commerce platform or a shared cache so that revoked tokens are rejected. Session TTL and refresh token rotation are set to limits that your security policy requires.

Can we federate logins from a corporate directory (Active Directory or Okta)?

Yes. Auth0 can act as a broker for SAML or OAuth 2.0 connections to your corporate directory. iWeb configures the federation connection and maps attributes from your directory (e.g. department, cost-centre, role) to Auth0 groups. When a corporate user logs in via SSO, they are automatically assigned the correct group and permissions.

How do we handle password resets and account recovery?

Auth0 manages password resets natively via email links. iWeb configures password reset policies (expiry, complexity, history) in Auth0 and ensures that reset emails are sent from your brand email address. If a customer resets their password in Auth0, the commerce platform does not need to be updated; the new password is valid on the next login.

What if a user has multiple email addresses or identities?

Auth0 supports account linking where multiple identities can be linked to a single user profile. iWeb configures the linking rules to merge identities by email domain or custom identifier. The commerce platform sees a single customer record even if the user has logged in via multiple identity providers.

How do we audit who logged in and what permissions they used?

Auth0 logs all login events, group changes and token issuances. iWeb configures Auth0 log exports to a secure audit system (SIEM, data warehouse or log aggregator) for retention and compliance. We set up dashboards and alerts for suspicious activity (failed logins, permission escalation, bulk deprovisioning).

What happens if Auth0 is down or slow?

If Auth0 becomes unavailable, login attempts fail and customers cannot access the storefront. iWeb recommends configuring Auth0 high-availability and failover rules, and optionally caching recent session state in the commerce platform to allow critical paths (cart checkout) to continue with reduced functionality. A communication plan and fallback process (e.g. staff-assisted orders) should be defined before launch.

Can we use Auth0 for both customer and staff logins?

Yes. Auth0 can manage both customer identities (for the storefront) and staff identities (for admin portals, call centres, backoffice tools). iWeb configures separate applications in Auth0 for each use case and ensures that staff tokens have different permissions and policies (e.g. longer session TTL, no MFA) than customer tokens.

How do we handle API access (order APIs, catalogue APIs) for B2B integrations?

Auth0 issues OAuth 2.0 or API tokens for programmatic access. iWeb configures scopes and token policies so that B2B partners can call commerce APIs (orders, shipments, invoices) with their buyer-specific permissions. Partner applications authenticate using their credentials and receive a token scoped to their allowed actions.

Can Auth0 enforce password strength and rotation policies?

Yes. Auth0 allows you to configure password policies (complexity, minimum length, expiry, re-use history). iWeb sets policies that match your security posture; for trade accounts, you can enforce more stringent requirements (e.g. 90-day rotation, uppercase / lowercase / numbers / symbols) than for consumer customers.

What data does Auth0 store about our customers, and how is it protected?

Auth0 stores usernames, email addresses, hashed passwords, groups, roles and custom attributes. Auth0 is SOC 2 compliant and encrypts data in transit and at rest. iWeb ensures that sensitive data (credit card numbers, full PII beyond login credentials) are not stored in Auth0; only references (customer ID, email) are kept so that Auth0 remains a lightweight identity layer.
