The impact is only that more people teleport from btt to altt. But I hope that everyone who teleports can still maintain the security of their account on BTT. By not using the same password to be in different forums but with the same name. Because if one of the accounts in the forum has been successfully infiltrated by someone else, it will be the same as our accounts in other forums. So the most important thing is to have a different password for each account we have on other forums.
It's never recommended to use the same password across multiple accounts, but we now have an additional line of defense to protect Bitcointalk accounts. You have probably noticed that the forum now allows to set up 2FA. So, even if your password leaked, whoever gets their hands on it would also need the 2FA code, assuming that you set it up.
Now I only understand the importance of 2FA after hearing your explanation about the problem of password leaks. At first I ignored this feature because I still felt that I didn't need this feature. But you are right that with 2FA our account security becomes thicker or more layered. thanks
It seems I really have to thank the person who came up with the idea of adding (optional) 2FA to this forum, namely PowerGlove. Thanks very much PowerGlove.
