Every business owner knows the drill when an employee departs – collecting company property, processing final payments, and handling paperwork. But in today’s digital workplace, there’s a crucial step that often slips through the cracks – revoking digital access.

And in 2026, that means much more than simply disabling an email account or changing a password.

The hidden risk

It’s easy to overlook dormant user accounts amid daily operations. While these forgotten logins might seem harmless, they can create significant security vulnerabilities.

Former employee access is no longer limited to traditional usernames and passwords. Employees may have access to Microsoft 365 or Google Workspace, cloud applications, CRMs, accounting systems, payroll platforms, vendor portals, file-sharing services, social media accounts, AI tools, automation platforms, and other business systems.

They may also have authorized applications to access company information through “Sign in with Microsoft” or “Sign in with Google,” created API connections between systems, or set up automations that continue running long after they leave.

That means simply turning off an employee’s primary account may not shut every door.

Why it matters now

Dormant accounts aren’t just a security liability. They can also be a hidden financial drain. Many organizations unknowingly continue paying for unused software licenses and subscriptions tied to former employees.

More importantly, forgotten accounts, active sessions, connected applications, and old credentials create potential access points for cybercriminals.

Businesses today rely heavily on cloud applications, and many employees accumulate access to dozens of systems over time. Some applications maintain their own active sessions, meaning access may continue until the session, token, or application permission is specifically revoked.

The same applies to integrations between applications. API keys, service accounts, access tokens, and automation credentials may continue working even after an employee’s personal account has been disabled.

AI adds a new kind of access

AI is creating another offboarding challenge.

Employees may now use AI assistants, custom GPTs, Copilots, agents, or automation tools that connect to company email, files, SharePoint, OneDrive, Teams, CRMs, project management systems, or other business applications.

They may have uploaded company information to AI platforms, created automated workflows, or given AI tools permission to retrieve information or take actions within other systems.

An important offboarding question is now:

What did this employee create, connect, automate, or give access to while they worked here?

An AI agent or automated workflow may even have permissions of its own and continue operating after the employee who created it has left.

Businesses therefore need to identify not only which applications an employee used, but also which AI tools, agents, integrations, and automations they created, connected, owned, or managed.

Building a stronger security foundation

Access audits shouldn’t be a one-time effort. Create a systematic approach that includes:

  • Quarterly reviews of active user accounts and permissions
  • Documentation of business applications, cloud services, AI tools, integrations, and automations
  • Clear protocols for immediate access termination
  • Review and revocation of active sessions, authentication tokens, and connected applications
  • Regular assessment of subscription costs and software usage
  • Identification of who owns critical accounts, applications, automations, and integrations

Companies should also review OAuth permissions. These are the permissions employees grant when they connect one application to another, often by clicking options such as “Sign in with Microsoft” or “Continue with Google.”

An employee may have authorized another application to access company email, calendars, files, contacts, or other business information without ever creating a separate password. Those connections need to be identified and revoked when appropriate.

The real impact

Consider this: Every dormant account is like leaving a spare key to your business hanging outside your door.

The risk multiplies when you consider shared passwords, those convenient logins used across teams for social media, vendor portals, collaborative tools, or other business systems. A former employee may not just walk away knowing their own login credentials. They may still know the credentials to multiple company accounts.

Whenever possible, employees should have individual accounts rather than shared logins. When shared credentials are unavoidable, passwords and associated MFA or account recovery information should be changed immediately when someone with access leaves.

A secure business password manager can also help organizations control shared credentials without employees needing to know or store passwords themselves.

While you’re focused on growing your business, forgotten access points can remain available to potential bad actors. Cloud security incidents often begin with these seemingly small oversights, turning preventable vulnerabilities into expensive business disruptions.

Don’t forget ownership

Offboarding isn’t only about removing access.

Companies also need to determine who will take ownership of the departing employee’s business information and resources.

This might include:

  • Email and shared mailboxes
  • Company files and folders
  • Calendars
  • CRM records
  • Dashboards and reports
  • Vendor accounts
  • Automations and workflows
  • API integrations
  • AI assistants and agents
  • Cloud applications or projects

Ownership should be transferred to the appropriate employee before accounts are deleted. Otherwise, a business can unintentionally lose access to important information or disrupt an automation or business process that employees were relying on.

Moving forward

Protecting your business doesn’t have to be overwhelming. Start with these practical steps:

  1. Create an employee offboarding checklist that prioritizes terminating digital access.
  2. Maintain an updated technology inventory that includes business applications, cloud services, AI tools, integrations, APIs, service accounts, automations, and company devices.
  3. Revoke more than the password. Terminate active sessions, authentication tokens, MFA methods, connected applications, and third-party access where appropriate.
  4. Schedule regular access reviews to identify unused accounts, excessive permissions, forgotten applications, and unnecessary access.
  5. Document who has access to what systems and who owns critical applications, automations, integrations, and AI tools.
  6. Transfer ownership before deleting accounts so that company data, workflows, and business processes remain under company control.

Frequently Asked Questions

Straight answers to the questions we hear most often about employee offboarding and digital access.

The employee’s access should be removed from all company systems at the appropriate time, including email, Microsoft 365 or Google Workspace, cloud applications, file-sharing platforms, CRMs, VPNs, vendor portals, and other business systems. Companies should also revoke active sessions, review connected applications, change shared credentials when necessary, recover company devices, and transfer ownership of important files and accounts. In 2026, offboarding should also include AI tools, automations, API connections, and other applications the employee may have created or connected.

An IT offboarding checklist should include disabling user accounts, revoking active sessions, removing access to business applications, recovering or securing company devices, changing shared passwords when necessary, removing MFA methods, transferring company data, and documenting the steps that were completed. The checklist should also account for cloud applications, AI tools, OAuth connections, APIs, service accounts, and automations that may continue operating after the employee leaves.

Yes, if all of their access has not been properly removed. A former employee may still have access through an active account, saved browser session, shared password, cloud application, connected app, API token, personal device, or another system that was missed during offboarding. This is why simply changing a password or disabling one account may not be enough.

Employee offboarding is typically a shared responsibility. HR or management should notify IT when access needs to be removed and specify the correct timing. The company’s internal IT team or managed service provider (MSP) can then handle the technical offboarding, including disabling accounts, revoking access, securing devices, transferring data, and documenting the process. Managers may also need to identify important files, applications, automations, or business processes that need to be transferred to someone else.

Removing a former employee involves more than deleting the user account. The business should disable sign-in, revoke active sessions, preserve or transfer email and files, remove access to shared resources and applications, review MFA and registered devices, and check for connected third-party applications. Businesses should also identify other systems the employee accessed outside of Microsoft 365 or Google Workspace, including SaaS platforms, AI tools, automations, APIs, and vendor accounts.
