My Bluehost site is expiring. I'm renewing the domain name if I want to restart it in the future.

But, I'm not sure if it stops me from signing into my Wordpress for my domain in the future? If so how can I make sure the log in is safe for it?

I have the log in of course but there's no 2FA. I guess I could use google authenticator but I hate having yet another app.

I always worried with a plug in what if there is an issue that stops me from logging in?
