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?
Yes, you can but your explanation is somehow confusing, do you lost your email password or the forum? If it the forum password you lost there's no need for you to change your email address.
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.
The only existing solution is to write a signed message using a Bitcoin address you have once used on the forum but since you participate in the bounty which I am not sure you have for once participate in a signature campaign.
I will advise you to stake the Bitcoin address you may use in the future
