Sometimes when making accounts online the suggested password prompt doesn’t show up. Until now I had been using an online random password generator to make the password when the prompt is not available. I just found out that if I go to the passwords screen in settings an manually add an account the password field is pre-filled with a random password which is very convenient.
Yeah I don’t want to enter long passwords either. But I don’t really like external password manager like 1password, lastpass and bitwarden. So I stay with my ios password manager. It works pretty fine. I do save my passwords in my desktop browser for easier use.
