Hello @Anna317,
Welcome to the community forum and thanks for posting.
I understand your concern regarding the change of your username. If you're referring to change/edit the PayPal.Me link, once you create your PayPal.Me link it cannot be changed. Here's the help center article to know more information about PayPal.Me. If you need any account-related concerns, please reach to our customer support team via the contact options on our website.
I hope this helps,
Ayesha
