Currently sign up forms are doing away with confirmation of passwords
and email.. so would this apply to a change password form, not to have
the user enter repetitive information?
The function of repetition of passwords is the same in a sign-up form as it is in a change password form. So, given the judgment that there is no need for repeating the password when signing up, the same should apply to changing the password.
That said, I'm not convinced that confirmation of the password should be removed in the first place. There is no way to see that you entered the password wrongly, and that is a real possibility--especially with increasing requirements for strong passwords, as well as more people using touch screens. Consequences:
- When the password is entered incorrectly, it is a hassle to change.
- The user might not realise their mistake, instead assuming the site is broken and wondering why they can't log in. This potentially creates support problems.
The repetition of email addresses is another thing (ARGH!). It is pretty annoying to have to do this when you can see the address on the screen. But I still favor asking for the password twice.
