Step-By-Step Guide to Fix Singpass 85-cv900 Error

Follow this straightforward step-by-step guide to successfully troubleshoot and fix the 85-cv900 error with Singpass:

1. Double Check Username and Password

The first step is to ensure you are using the correct Singpass username and password:

  • Your username is your NRIC or FIN number (no spaces or dashes).
  • The password is the one you set up when creating your Singpass account.

Carefully re-enter both and try logging in again. Many 85-cv900 errors are caused by simple typos in the login credentials.

2. Reset Password if Forgotten

If you have forgotten your Singpass password, use the password reset function:

  • Go to Singpass website and click Forgot Password
  • Enter NRIC and email address registered to Singpass account
  • Select delivery method for one-time password (OTP) – via SMS or app
  • Input OTP received to reset password

Create a new strong password you can remember. Test logging in to Singpass with new password.

3. Check Account Security Questions

Singpass uses security questions for identity verification when resetting passwords or unlocking accounts.

Ensure your account security questions are set up properly with answers you can recall accurately.

To update security questions and answers:

  • Log in to Singpass Profile page
  • Click Security Questions tab
  • Edit or update questions and matching answers
  • Save changes

Providing wrong answers to security questions can lead to 85-cv900 errors.

4. Unlock Account if Locked

Too many wrong password attempts will lock access to your Singpass account as a security measure. This causes 85-cv900 errors even with the right password.

To unlock a locked Singpass account:

  • Go to Singpass forgot password page
  • Click Unlock Account option
  • Enter NRIC and registered email
  • Select OTP delivery method and input OTP received
  • Answer security questions correctly
  • Account will be unlocked

You can now log in with the right password credentials.

5. Update Singpass App

An outdated Singpass app version can also be the culprit behind 85-cv900 errors.

Ensure you are running the latest version of the Singpass app:

  • On your mobile device, go to the App Store or Play Store
  • Search for Singpass app
  • Check if there are any available updates and install them
  • Alternatively, uninstall and reinstall the latest Singpass app

Updating to the newest app version helps avoid compatibility issues that cause login errors including 85-cv900.

6. Use Latest Browser Version

Like apps, outdated internet browsers can also conflict with the login protocol and generate 85-cv900 errors.

If accessing Singpass via browser, make sure it is up to date:

  • On your computer, open the browser (Chrome, Firefox etc)
  • Click on Help or About menu to check current browser version
  • Update browser to latest available version
  • Reboot computer for changes to take effect

The newest browser versions have the proper security configurations and compatibility for smooth Singpass access.

7. Clear Browser Cache and Cookies

Large amounts of cached data and cookies on your browser can sometimes disrupt the Singpass login process and cause 85-cv900 errors.

Clearing this data forces a fresh login attempt:

  • Open your internet browser and click Settings
  • Go to Privacy & Security options
  • Click on Clear Browsing Data button
  • Select cached images/files and cookies & site data to remove
  • Click Clear Data button to confirm
  • This will wipe the browser cache and cookies allowing a fresh Singpass login.

8. Try Logging in on Different Device

As a test, attempt to log in to your Singpass account on another device like a mobile phone or tablet.

If you can successfully access Singpass without 85-cv900 errors on the second device, the issue lies with your original device. This confirms it is a device-specific technical issue rather than your account credentials.

You can then troubleshoot the original device further or simply use the working second device for Singpass access in the interim.

9. Contact Singpass Technical Support

If you still face 85-cv900 errors after trying all the above troubleshooting steps, technical issues on Singpass’s end could be causing the problem.

Contact Singpass support for assistance:

  • Live chat with support agents at Singpass website
  • Call 6643-0555 during office hours for Singpass helpdesk
  • Email [email protected] with details of issue

Singpass technicians can then diagnose server or system problems causing the 85-cv900 error and resolve it.

Preventing Future 85-cv900 Errors

Once you have fixed the current 85-cv900 error, take these measures to avoid recurring issues in the future:

  • Enable two-factor authentication (2FA). Add another credential like OTPs during login to enhance security.
  • Change password periodically. Reset your Singpass password every few months as a security best practice.
  • Use strong unique passwords. Create passwords that are long, complex and not used on other accounts.
  • Keep software updated. Regularly update Singpass app, browser, operating system and security software.
  • Use antivirus software. Install a robust antivirus program to detect malware that may disrupt Singpass access.
  • Beware of phishing. Do not click suspicious links asking for Singpass credentials to avoid getting scammed.
  • Log out properly. Always use Singpass’s proper log out function instead of just closing the app or browser.

Following these tips boosts Singpass security and significantly reduces risks of further 85-cv900 errors occurring.
