1Password's password generator lets you control whether your password should contain "digits" and "symbols". The problem is that in my experience, most sites that ask you to include symbols in your passwords really want you to include some limited subset of symbols. Furthermore, every site has its own idea of what the acceptable symbols are. This dramatically reduces the usefulness of the 1Password password generator.
In practice, what I usually do is to have 1Password generate a password; copy it into a text editor; go through it, replacing the symbols that 1Password chose with symbols in the site's acceptable symbol set; copy the password back out of the editor; and paste it into the web site's password entry fields. Ugh.
What is really needed is an additional field in the password generator to let us optionally specify a restricted set of acceptable symbols.
Yeah. ugly, It makes an already complicated dialog even denser. But: is a simpler interface that only works half the time really better than a more complicated, more general interface?
