Recovering a Hi5 account is quite simple if you have access to the email address used for registration.
Step 1: Go to the account reactivation page
Go directly to the account reactivation link: https://geometrydash-lite.io https://www.hi5.com/reactivate_account.html
Step 2: Enter your email address
On this page, you will find a field where you need to enter the email address associated with your Hi5 account.
Step 3: Follow the instructions received via email
After you have entered your email address and submitted the request, Hi5 will send you an email with a link. Access that link to choose a new password and reactivate your account.
