Can I change my username after I use all available attempts?

No. You can change your username only a limited number of times. After you use all allowed attempts, you cannot change it again.

How do I report or delete an impersonated account?

Contact HackerRank support at help@hackerrank.com and provide details about the impersonated account. The support team reviews the request and takes appropriate action.

Why does my public profile link show a 404 error when other users open it?

Other users see a 404 error when your public profile has no visible activity.

This occurs when your account has no visible activity, such as:

• No completed challenges

• No earned badges

• No public certifications

Your profile becomes publicly accessible once you complete at least one challenge or earn a badge.

Why does my profile URL stop working after I change my username?

When you change your username, your HackerRank profile URL automatically changes to match it. The previous URL becomes inactive and may show a 404 error.
To resolve this:

1. Copy and share your new profile URL.

2. Update any bookmarks or references that use the old URL, such as in resumes, portfolios, or job applications.

Example:

• Old: https://www.hackerrank.com/profile/{oldusername}

• New: https://www.hackerrank.com/profile/{newusername}
