## Troubleshooting Common Login Issues If you encounter errors when attempting to log in, first confirm you are using the correct city-issued username and password, and that you are on the official philly.phila.gov domain. Failed login attempts after a set number of incorrect entries will temporarily lock your account for security purposes; to unlock a locked account, you will need to contact the city's employee IT support team to verify your identity. If you see an error indicating the page is unavailable, clear your browser's cache and cookies, or try accessing the portal from a different browser or device. For employees logging in remotely from outside city-owned networks, confirm with your department's IT guidelines if you need to connect to the city's approved virtual private network (VPN) to access the ESS One portal, as many municipal employee systems restrict off-network access for security reasons.

How to Log In to the ESS One philly.phila.gov Employee Portal
To log in to the ESS One employee portal for City of Philadelphia staff, navigate directly to the official philly.phila.gov domain, select the employee login option, enter your assigned city-issued credentials, and complete any required multi-factor authentication prompts to access your account. The portal is the official self-service platform for city employees to manage pay stubs, benefits, leave requests, and other employment-related information, and all access is restricted to authorized city personnel with active accounts. ## Locating the Official ESS One Login Page The only legitimate ESS One login page is hosted exclusively on the philly.phila.gov domain, so avoid entering credentials on any third-party sites, pop-up windows, or links from unverified emails that claim to connect to the employee portal. If you are accessing the portal from a city-owned device on a city network, you can also reach the login page via your department's official employee intranet homepage. If you are unable to locate the correct login page, contact your department's internal IT support or the city's central employee help desk for the verified direct URL to avoid phishing risks. ## Required Login Credentials ESS One does not support personal or public user accounts; all logins require unique credentials issued by the City of Philadelphia to active employees. For most staff, your username is your assigned city employee ID number, and your password is the secure credential you set during your initial onboarding process, or updated via the city's official password management system. New hires receive temporary login credentials during orientation, with instructions to set a permanent password within the first 14 days of employment. If your password has expired, use the official "Forgot Password" link on the ESS One login page to reset it using your registered city contact information, rather than reaching out to unverified support channels. ## Completing Multi-Factor Authentication After entering your valid username and password, you will be required to complete multi-factor authentication (MFA) to verify your identity before accessing your ESS One account. Most city employees are enrolled in the city's standard MFA protocol, which may deliver a one-time verification code to your registered city-issued email address or phone number, or require approval via a city-approved authentication app installed on your personal or city-issued device. If you have not yet completed MFA enrollment, you will be guided through the one-time setup process the first time you log in after your employee account is activated.
