Nowadays, when a webapp offers a registration page, it usually duplicates the password field (or sometimes even the email field). By having you type the password twice, it wants to ensure that you didn’t make any mistake. And that you don’t have to reset the password the next time you try to login. It makes sense if you actually type the password. Me, I’m using a password manager. That means, I do a copy-paste the password I got from the password manager twice. So far, so good
