I have sought for where I wrote down the password of account but for a while now I can't find it. What if I have misplaced it completely and end up not seeing it is there anyway I can change my email address to avoid missing my account in the future?

This has given me lots of concern for days I have been wondering what would happen if I misplace my device and forget my login details on this platform or I wish to change my password in the future to safeguard my account from hackers without having access to my email address it would mean the account is fully gone.

I wish to get a solution if any exist on how to get a new mail in case in can't find my password.
