ServiceTitan Sign-In Help for Employees, Technicians, and Customers
By Amanda Keller, contractor-software support lead with 8 years of account and mobile-access experience
Last reviewed: July 12, 2026
Most office employees access ServiceTitan through the company’s main tenant, while technicians, enterprise administrators, and customers may use separate environments. Confirm the type of account before resetting anything, because a tenant password will not necessarily repair Enterprise Hub, mobile-product, or Customer Portal access.
This independent guide is not ServiceTitan and cannot create, inspect, unlock, or change an account.
What ServiceTitan login are you trying to reach?
ServiceTitan is a software platform for residential and commercial contractors. It supports service visits, construction projects, proposals, reporting, service agreements, and other operational work.
One contractor can have several groups using the platform:
| Person or task | Environment to check |
|---|---|
| Office employee | Main ServiceTitan tenant |
| Field technician | Field Mobile App or ST Field |
| Technician using inventory tools | Inventory Mobile |
| Administrator managing several tenants | Enterprise Hub |
| User testing enterprise preview features | Enterprise Hub Next |
| Contractor customer | Customer Portal |
Those environments may share ServiceTitan branding without sharing the same access rules.
An employee who reaches Enterprise Hub but cannot open one tenant has a tenant-specific problem. A technician who enters ST Field but cannot use Inventory Mobile may be missing product access. A homeowner trying to view an invoice needs the contractor’s portal, not the employee application.
Start with the failed job. Skip password recovery until the environment is clear.
Use the main application, not a saved authentication page
Standard tenant users should start from the main ServiceTitan application. ServiceTitan’s official tenant-recovery instructions direct users to go.servicetitan.com, then to Forgot Password? when recovery is needed.
Do not save a temporary authentication address as the main bookmark.
ServiceTitan’s login page displays the exact warning “Your login page has expired!” when the page is outdated. Its instructions say to return to the main application instead of using an old bookmark or saved login link. The page also states that JavaScript is required.
This is a page problem.
It does not prove that the username or password is invalid. Close the expired tab, open the main application directly, and begin one fresh session.
When the login interface is blank or incomplete, check whether JavaScript is being blocked. On a managed company computer, involve internal IT rather than changing organization-controlled browser settings.
Do this first. Skip a password change until the current official page actually rejects the account.
Reset the tenant account that actually failed
ServiceTitan documents two closely related tenant-recovery paths.
One official article instructs users to open the main application, select Forgot Password?, enter the account email, and reset the password for the individual tenant. It specifically warns that this does not reset the Enterprise Hub password.
Another current troubleshooting article says the Reset your password screen can accept the username, email address, or mobile phone number associated with the account, followed by Submit.
Follow the field shown on the current page.
The value used for sign-in may differ from the recovery contact. For example, an employee might sign in with an assigned username while receiving recovery instructions through an email address stored on the profile.
Use the newest recovery message only. Several requests can produce several messages, and an older link may no longer correspond to the current attempt.
When nothing arrives, ask the employer’s ServiceTitan administrator to verify the profile status, assigned username, tenant, email address, and mobile number. Do not keep testing unrelated addresses.
ST Field login uses the technician’s assigned account
ServiceTitan’s May 2026 Field Mobile instructions tell iOS users to open ST Field, tap Sign in, enter their Username and Password, and tap Sign In. Android users follow a similar process through the Field application.
Installing the application does not create access inside the contractor’s ServiceTitan tenant. The employer must already have a technician profile and the required product access configured.
Before reinstalling the app, confirm:
- The correct field application is installed.
- The technician is entering the assigned username.
- The technician profile remains active.
- The device has a stable connection.
- The employer has enabled the appropriate mobile product.
Username first. Reinstallation later.
ServiceTitan says technicians can use Forgot Password from the mobile sign-in screen. Its current documentation lists several reasons a reset may appear, including temporary credentials, a forgotten password, and a security prompt after one year.
That one-year prompt is documented behavior, not automatically evidence of an account problem.
Why a working ST Field account may fail in Inventory Mobile
A successful sign-in to one ServiceTitan mobile product does not prove that every mobile product is enabled.
ServiceTitan has a dedicated troubleshooting article for technicians who can enter the standard mobile app but cannot sign in to Inventory Mobile. The office administrator is told to check the technician’s connection, compare Wi-Fi with cellular data, look for firewall or VPN interference, and confirm that Inventory Mobile is enabled in ServiceTitan Settings.
The order matters:
- Confirm Inventory Mobile is enabled.
- Check the technician’s assigned access.
- Compare Wi-Fi and cellular behavior.
- Review the account.
- Reset credentials only when the login itself is rejected.
A valid password cannot activate an unassigned product.
Network behavior varies by carrier, device policy, employer configuration, and region. Record the result precisely. “ST Field works on cellular, but Inventory Mobile fails on office Wi-Fi” is actionable. “ServiceTitan mobile is broken” is not.
Enterprise Hub uses another recovery layer
Enterprise Hub is ServiceTitan’s environment for managing supported users, tenants, roles, and access across multiple locations. ServiceTitan’s current documentation says users sign in with an Enterprise Hub username and password.
Its password-reset page requests the email address associated with the account and says a reset link will be sent by email.
That creates three distinct items:
- Enterprise Hub username
- Enterprise Hub recovery email
- Individual tenant password
They may not match.
When Enterprise Hub itself rejects access, use the recovery process on the Enterprise Hub page. When Enterprise Hub opens but one tenant does not, investigate the tenant instead.
ServiceTitan allows an authorized administrator to select Send Password Reset for the affected tenant user. The user can also return to the main application and submit the identifier associated with that tenant account.
Reset one layer only.
Changing both Enterprise Hub and tenant credentials at the same time removes a useful diagnostic clue and can leave the user unsure which new password belongs to which page.
Try a clean Enterprise Hub browser session
Browser state can interfere with Enterprise Hub even when the account remains valid.
ServiceTitan’s current troubleshooting guide recommends using a Chrome incognito window and testing Enterprise Hub again. Its documented process also includes clearing browsing data when needed.
Test incognito mode first. It is less disruptive than deleting all stored browser data.
The outcome helps classify the issue:
- Works in incognito: stored browser state may be involved.
- Fails in every browser session: account or service access deserves more attention.
- Enterprise Hub works but one tenant fails: investigate that tenant.
- Several users fail at once: escalate as a broader issue.
Specific observations shorten the handoff.
Enterprise Hub Next uses the live Hub credentials
Enterprise Hub Next has its own address, but ServiceTitan says users should sign in with the same username and password used for the live Enterprise Hub account. When those credentials fail, users are directed back to the regular Enterprise Hub page and Forgot Password?
Do not create a second password simply because the environment is labeled Next.
Use the result to narrow the problem:
- Live Hub and Next both fail: check the shared Enterprise Hub account.
- Live Hub works and Next fails: report an environment-specific issue.
- One tenant alone fails: check the tenant assignment or tenant credentials.
Small distinction. Useful evidence.
MFA errors are not ordinary password errors
ServiceTitan supports multi-factor authentication and maintains separate guidance for account locks, session expiration, code problems, and mobile login failures.
Its current MFA troubleshooting page shows a Session Expired error when an authentication session times out and an account-lock message after the allowed login attempts are exceeded.
Stop repeated attempts early.
Separate the symptoms:
- The password is rejected before MFA.
- The MFA screen appears but no code arrives.
- The authenticator code is rejected.
- The session expires.
- The account becomes locked.
- The mobile app receives verification but still reports login failure.
Each stage points toward a different action. A tenant password reset will not necessarily repair an expired MFA session or an account lock.
Route administrator-controlled MFA actions to the employer’s authorized ServiceTitan administrator.
Customers need the contractor’s portal link
The ServiceTitan Customer Portal belongs to the contractor using it. Customers do not use the internal employee login.
ServiceTitan says customers can access the portal through a link emailed or otherwise provided by the contractor. On the portal login page, they can select Request an invitation to register.
The portal can display outstanding invoices and service history. Customers can still view those records when ServiceTitan Payments is not enabled, but they cannot make a payment through the portal in that configuration.
ServiceTitan also documents a current registration flow in which the customer selects Request an invitation, checks the email associated with the customer record, and verifies the account.
Contact the contractor first when:
- The portal address is missing.
- No invitation arrives.
- The customer’s email is not recognized.
- An expected invoice or service record is absent.
The contractor controls the customer record, invitation settings, and available portal functions.
When to contact ServiceTitan support
Contact the employer’s administrator first when the problem involves an unknown username, inactive profile, missing mobile product, tenant assignment, Enterprise Hub access, or MFA management.
Use ServiceTitan Technical Support after the correct product, profile, recovery route, browser session, and network have been checked.
ServiceTitan’s support documentation says users who cannot sign in to reach the Help Center should try the Forgot password? process first.
Provide the product name, device or browser, approximate failure time, connection type, and exact non-sensitive error wording. State whether the issue affects one user or several.
That gives support a practical starting point.
Frequently asked questions

Yes. The current reset screen may accept an associated username, email address, or mobile phone number.
Does resetting a tenant change Enterprise Hub?
No. ServiceTitan documents them as separate passwords.
Why can ST Field work while Inventory Mobile fails?
Inventory Mobile may not be enabled, or the account, network, firewall, or VPN may need review.
Does Enterprise Hub Next need another password?
No. It uses the live Enterprise Hub credentials.
