Yeah true. Another option is to copy proton mail, using a 12 word recovery phrase. Nobody will ever guess that.
I think the major problem is, when using the lost password method, the method to get into your account has been made significantly easier. Where a password is relatively difficult to guess, a hacker can get around this by replacing it by a 4 digit number. The method to get into an account using the lost password method should not be a lot easier than using a password, which a 4 digit number clearly is.
