Troubleshooting Bullhorn ATS Login Issues

Learn how to diagnose and fix the most common reasons a user can't log in to Bullhorn. Work through the steps below in order — most login issues are resolved within the first two steps.

You'll need Admin-level access to complete these steps. If you're a user trying to log in yourself, see How to Log In to Bullhorn ATS.

Step 1: Confirm the User's Credentials

Many login failures come down to incorrect credentials. Before making any changes to the account, confirm the following:

  • The user is entering their Bullhorn username, not their email address.

  • The password is being entered correctly. Passwords are case-sensitive.

  • The user is using the correct login URL: https://www.bullhorn.com/client-login/

Step 2: Reset the User's Password

If the user has forgotten their password or is receiving an invalid credentials error, reset it from the Admin panel.

  1. Go to Menu > Admin > Users.

  2. Click the pencil icon next to the user's record.

  3. In the Account Information section, enter a new password in New Password and confirm it in Retype new password.

  4. Click Save.

  5. Share the new password with the user and ask them to update it straight away from their Preferences page.

  6. Ask the user to check their browser's saved passwords and remove any stored Bullhorn credentials before logging in again.

For full password requirements and additional steps, see Changing a User's Password.

Step 3: Check the Account Status

A user can't log in if their account is disabled or locked. Check the account status from the user record.

Disabled Accounts

A disabled account means the user has been deactivated — either intentionally (for example, they left the company) or by mistake. To check and re-enable:

  1. Go to Menu > Admin > Users.

  2. Open the user's record by clicking the pencil icon.

    Disabled users may not appear in your default list view. If you can’t find the user, set the filter at the top of the list to Disabled.

  3. Under Account Information, check the Account field. If it shows Disabled, change it to Active and click Save.

Re-enabling a disabled account makes it billable again. If the total number of active users exceeds your contract limit, additional charges may apply. Contact your Account Manager if you're unsure.

Locked Accounts

Accounts lock automatically after multiple failed login attempts or after 90 days without a successful login. A locked account is still active — it just needs to be unlocked.

  1. Go to Menu > Admin > Users.

  2. Open the user's record and check the Account field under Account Information.

  3. If the status shows Locked, change it to Unlocked and click Save.

For full steps and FAQ, see Locking and Unlocking a User Account.

Step 4: Check Login Restrictions

Bullhorn lets admins restrict user access by IP address, time of day, or day of the week. If a user is being blocked despite having the correct credentials and an active, unlocked account, check whether a login restriction is preventing access.

  1. Go to Menu > Admin > Users and open the user's record.

  2. Expand the Login Restrictions section.

  3. Check for any IP addresses, time ranges, or day restrictions that might be blocking the user's current login attempt.

  4. Adjust or remove the restriction if appropriate, then click Save.

Time-of-day restrictions apply in Eastern Standard Time (EST), regardless of the user's local time zone. If your organisation is in a different time zone, adjust the restriction hours accordingly.

For more detail on how restrictions work, see Restricting User Login.

Step 5: Check for SSO Issues

If your organisation uses Single Sign-On (SSO), login failures may be caused by the identity provider rather than Bullhorn itself.

  • Confirm there are no company-wide outages with your SSO provider (Microsoft Azure AD, Okta, Google, ADFS, and so on).

  • Confirm the user's SSO account is active and not locked or expired at the identity provider level.

  • If the user is logging in from a new device or location, they may need to complete additional verification steps required by your identity provider.

Step 6: Verify the Username

If none of the above resolves the issue, double-check that the username in Bullhorn exactly matches what the user is entering. Usernames are case-insensitive in Bullhorn, but typos or extra spaces can cause failures.

  1. Go to Menu > Admin > Users and open the user's record.

  2. Confirm the Username field exactly matches what the user is typing at login.

Usernames can't be changed after a user account has been created, as this can cause data integrity issues. If the username is incorrect and must be changed, contact Bullhorn Support.

Still Can't Resolve the Issue?

If the user still can't log in after working through all the steps above, contact Bullhorn Support for further assistance.

FAQ

Why did the user's account become locked?

Accounts lock automatically after multiple consecutive failed login attempts, or after 90 days without a successful login. An Admin can unlock the account at any time.

The user reset their password but still can't log in. What should I check?

Ask the user to clear their browser cache and cookies, close and reopen the browser, then try again. Cached sessions can sometimes cause stale credential errors. They should also check their browser's saved passwords and remove any stored Bullhorn credentials — an old saved password may be autofilling the login field without them realising. If the issue persists, contact Bullhorn Support.

A user says they were logged out unexpectedly. Why?

Bullhorn sessions time out after a period of inactivity. If the user was inactive for an extended period, they'll need to log in again. If this is happening frequently and unexpectedly, it may be related to browser settings or security software on their device.
