Instead of creating new emails, I create new passwords every time and securely save them on my computer.
please tell me you use a password manager or encrypt the file and don't just keep them in plain text.
Yeah, of course I don't keep them in plain text, I use a password manager and I've also encrypted the file, I've made multiple backups in case something goes wrong. At first, I had 2-3 passwords and was using them for different accounts but then I discovered that many website don't have good security and they often get hacked.
I know it's not a good practice but years ago, when I was a kid, I was using Google Chrome because it was very popular. I was saving my passwords on Google Chrome and then Chrome was reporting to me that most of my accounts were hacked and the password was leaked, so that was the moment that woke me up from my comfort zone and then I took all of these account-related things very seriously.
When you save your passwords in a browser, it is very risky because if you accidentally click on a phishing link, hackers will immediately hack your browser. And because of hacking browser cookies, they can hack all the saved passwords and all the data of the websites you browse. For this, you have to be very careful not to click on any kind of phishing link.
It is good to use a password manager but if you are a victim of an phishing attack and you click on that phishing link then you will not be safe from hacking. Hackers are always very smart and they will try to trap you by luring you in different ways. So always be careful about this. Then you can stay safe.
