🪜 How to Fix STI Portal “Wrong Credentials” Error (Step-by-Step):

Follow this tested step-by-step process to fix the STI portal login issue and regain access to your account.

🔹 Step 1 – Check Your Username and Password Carefully

• Ensure that your CNIC number is entered correctly without dashes (e.g., 3520198765432 not 35201-9876543-2).
• Make sure Caps Lock is OFF.
• Remove any spaces before or after your CNIC.
• Type your password manually instead of copy-paste to avoid hidden characters.

🔹 Step 2 – Clear Browser Cache and Cookies

Old cache data can prevent the latest login credentials from syncing.

Here’s how to clear it:

1. Open your browser (Chrome/Edge/Firefox).
2. Go to Settings → Privacy and Security → Clear Browsing Data.
3. Select Cookies and Cached Images → Click Clear Data.
4. Reopen the STI Portal and try again.

💡 Use Incognito Mode if you want to test login without clearing everything.

🔹 Step 3 – Use an Updated Browser or Device

Outdated browsers can conflict with the STI login portal.
Try the following combinations for best results:

⚠️ Avoid using mobile browsers like UC Browser or Opera Mini for STI login — they often cause verification errors.

🔹 Step 4 – Reset Your Password from Official STI Portal

If you’ve forgotten your password or it’s expired, you can reset it easily.

Password Reset Process:

1. Visit the official STI Portal.
2. Click “Forgot Password” under the login button.
3. Enter your registered CNIC or Email ID.
4. Check your email inbox or SMS for the reset link.
5. Create a new password (at least 8 characters, including one symbol and one number).
6. Log in again with your new credentials.

🔹 Step 5 – Check If Your Account Is Verified

Sometimes the portal rejects logins because the user’s account status is “Pending Verification.”

To fix this:

1. Visit your District Education Office (DEO) or contact their IT focal person.
2. Ask them to verify your STI record in the SED database.
3. Once approved, your login will be reactivated within 24–48 hours.

💬 Note: Many candidates face this issue after submitting joining letters or during transfer updates.

🔹 Step 6 – Try Logging in from a Different Device or Network

If the error persists, try:

• Using another laptop or PC.
• Switching from Wi-Fi to mobile data (or vice versa).
  Sometimes, ISP-level cache prevents authentication from refreshing.

🔹 Step 7 – Contact the STI Technical Support Team

If nothing works, you can directly reach out to the STI technical support team.

📌 Always include your CNIC, district, and issue screenshot when emailing.
