[Bug] Cannot modify the first digit of the character length of password generator web version
The bug happens here: A Secure, Strong Password Generator | 1Password
In the "Characters" section, there is a text box where you can enter the desired password length. However, any number less than 8 is not allowed to be entered as the first digit. This means that it is impossible to enter any character length number below 80.
The problem seems to be that because the web page restricts the password length to a minimum of 8, numbers less than 8 are restricted from being entered as the first digit. However, this makes it impossible to enter numbers between 10 and 79, which is a careless design.
