Default Password Exclusive: Pax S80
The Pax S80 is one of the most reliable workhorse credit card terminals on the market, but managing its security settings can be tricky if you are locked out of the system. Whether you are setting up a new device or updating your connection settings, knowing the correct administrative credentials is essential for business continuity. Common Pax S80 Default Passwords
Most Pax S80 terminals ship with a standard set of factory passwords. Depending on the specific firmware or your merchant service provider, one of the following codes will likely grant you access to the system menus: 9876: The most common default administrative password. Today's Date: Enter the current date in MMDDYYYY format. 1234: A common secondary backup or technician code. 0000: Used primarily on older firmware versions.
858234: A specific technician override code used by some processors. Accessing the Terminal Menu
To use these passwords, you typically need to enter the terminal's function menu. On the Pax S80, you can usually reach the password prompt by following these steps: Locate the Menu or Function key on the keypad.
Press the "Func" and "1" keys simultaneously, or simply press the "Menu" button. Select "System Settings" or "Terminal Management."
When the screen displays "Enter Password," input one of the codes listed above. Press the green "Enter" key to confirm. Why You Might Need the Admin Password
The Pax S80 requires administrative credentials for several critical maintenance tasks. You will likely need the default password if you are attempting to perform any of the following:
Changing Connection Types: Switching from a phone line (dial) to a high-speed Ethernet connection. pax s80 default password
Updating Firmware: Installing the latest security patches or software versions from the manufacturer.
Setting the Internal Clock: Adjusting the date and time to ensure transaction timestamps are accurate.
Clearing the Batch: Manually forcing a settlement if the automatic daily close fails.
Adjusting Receipt Headers: Changing your business name or phone number printed on customer receipts. Security Best Practices
While default passwords are helpful for initial setups, they represent a significant security risk if left unchanged. Once you gain access to your Pax S80 terminal, it is highly recommended that you navigate to the "Security" or "Change Password" section of the menu to create a unique code. This prevents unauthorized individuals from accessing your batch totals or tampering with your terminal configuration. Troubleshooting Failed Logins
If none of the common default passwords work, your merchant service provider (MSP) has likely set a custom administrative code before shipping the device to you. In this scenario, you should not attempt to "guess" the password repeatedly, as some firmware versions may temporarily lock the terminal.
Contact your processor's technical support desk. They can usually provide the specific override code associated with your Merchant ID (MID). If the terminal remains unresponsive, a factory reset may be required, though this should only be done under the guidance of a professional to avoid deleting your merchant programming.

| Function | Default Code | Notes |
|----------|--------------|-------|
| Manager Password | 123456 or 000000 | Primary focus of this article. |
| Supervisor Password | Same as manager | Often identical; sometimes 999999. |

Note: The Technician password (
166831) is especially dangerous. It allows access to kernel logs, key injection modes, and serial debugging. Never leave this default value unchanged if you have technical access.
2. Previous User Changed It
If you bought a used Pax S80 on eBay or inherited one from another business, the previous admin may have set a custom password. Without that password, the terminal is locked.
Real-world risks of keeping the Pax S80 default password:
- Unauthorized Settlements – A dishonest employee could settle a batch early and redirect funds.
- Configuration Tampering – Attackers could change the terminal’s IP address to a malicious proxy, capturing card data.
- Disabling Receipts – Turning off receipt printing to hide fraudulent transactions.
- Factory Reset – Wiping the terminal to install fraudulent software.
Factory Reset of the Pax S80: The Last Resort
If you have lost the password and your processor cannot help, a factory reset will restore the pax s80 default password to 123456. However, this wipes all payment applications and network settings.
Do not perform this unless instructed by support – you may brick the terminal’s ability to process payments.
Scenario 3: The manager menu has been disabled.
Some processors hide the Manager Menu entirely, requiring remote command injection via TLS. You cannot fix this on your own.
Solution: Contact your acquiring bank or payment gateway.
Why Won’t the Default Password Work?
There are three common reasons why the default Pax S80 password fails:
Why Do You Need the Pax S80 Manager Password?
Gaining access to the Manager Menu via the default password allows you to perform essential tasks:
- Settlement/Batch Close – Manually close out daily transactions.
- Wi-Fi & Network Configuration – Change from Ethernet to Wi-Fi or update IP settings.
- Application Management – Install or update payment apps (e.g., Dejavoo, Clover, TSYS, First Data).
- Diagnostics – Run hardware tests on the printer, card reader, or touchscreen.
- User Settings – Adjust receipt options, timeout durations, or tip settings.
- Reset to Factory Settings – Wipe the terminal for redeployment.
Without the correct password, you cannot perform any of these actions. This is why knowing and controlling the pax s80 default password is critical for daily operations.
