It is possible to create a login which doesn't need a password I was thinking that assigning passwords to OS X accounts is mandatory and you had to set the account to auto-login to avoid having to enter it every time. But can I also define a user account which doesn't need a password?
You do not have to set a password:


Start with Create new user account in System preferences - Users &amp; Groups
Under drop down choose for example Standard Account
Enter name and account but skip the password filed
You will get a warning about not having password, click OK


Account is now created without password.

The Guest account (if enabled) also doesn't require a password.
