Access Serko Expense Account
To access, please make your way to the Zeno Expense Homepage - https://expense.serko.com/
Enter your registered email address and your password.

For extra security, Zeno Expense supports Two Factor Authentication (2FA) for users that log into the desktop application using an email address and password or mixed authentication methods i.e., SAML+WEB access.
How it works?
If 2FA is enabled for your company, users will see the “TWO FACTOR AUTHENTICATION” option in the dropdown menu under the ‘person’ icon in the top menu bar.
Selecting this option will open the “Configure Two Factor Authentication” page where end-users can set up 2FA.
The page displays a QR Code which end users need to scan using Microsoft or Google Authenticator app on their mobile phone.
The app will generate a six-digit code which end users must enter in the “Code” field to set up 2FA. Please note, that the code generated by the authenticator app is time-sensitive (regenerates every 30 seconds), so users need to act quickly or wait for the next code.
Once a valid code has been entered, a confirmation message is displayed to let users know that 2FA has been enabled.
After a user has enabled 2FA, they’ll be prompted to enter a new 2FA code each time they log in to Zeno Expense (desktop only). To obtain a valid code, users must open the authenticator app they used to set up 2FA and type in the code displayed for their Zeno Expense account. Note, the authenticator app regenerates the code every 30 seconds so to authenticate successfully, users need to enter the code displayed in the app at the time of login.
If an invalid code is entered, users will be prompted to try again.
Remove/reset 2FA
If an end user loses their phone, Admin users can select the “RESET TWO FACTOR AUTH” button in their user profile to disable the 2FA requirement.
Note |
---|
The “RESET TWO FACTOR AUTH” option will only be displayed in user profiles that have 2FA set up. |
Clicking this button will remove 2FA functionality from the end user’s account, and they will need to re-enable it by selecting “Two Factor Authentication” from the drop-down menu and scanning the new QR code with their authenticator mobile app if required.
