how to change reddit username?

TLDR: Changing your Reddit username is generally permanent, but accounts created with Google or Apple ID can change it once within 30 days. For email accounts, the only option is to delete the account and create a new one, losing all history.

Changing your Reddit username is a rigid process governed by specific conditions. For accounts created using Google or Apple ID, users can change their username once within the first 30 days of account creation. However, for accounts created with an email address, the username is permanently attached, and the only way to change it is to delete the account and start anew, which results in the loss of all posts, comments, and karma.

To change your username, navigate to your profile on either desktop or mobile, and if eligible, a prompt will allow you to initiate the change. Once confirmed, the new username cannot be altered again, including its capitalization. It's also important to note that while the username is permanent, users can change their display name at any time without affecting their username or account history.
