For example, use a password manager, use 2FA.
I recognise that security through obscurity isn’t something you can rely on, so don’t consider my own practices to be secrets and am willing to share them to help others.
I use strong unique passwords stored in a KeePass database, and MFA whenever it’s available. I also have a VPN specifically so that I can use public Wifi when I have to (or wish to do something more private on the internet, such as downloading Linux ISOs).
I also have a vanity domain that redirects all mail to a central mailbox, so whenever I sign up for something I can easily use a unique address. This allows me to block specific addresses that produce spam and see where the spammers got that address.
I get that now, I thought you were just being snarky the first time I read it!
