Added a function that can automatically generate an email address and a set password.
When registering on other sites or apps using the email address generated with a throwaway email address,
Passwords can also be generated at the same time, which is convenient because they can be managed all at once on the disposable email address.
The password is generated with 12 to 18 characters including half-width numbers, half-width alphabets (lowercase), half-width alphabets (uppercase), and half-width symbols, and is strong and safe.
You can create the password at the same time you generate the address, or you can generate the password only later.
When the address is deleted, the password will also be deleted.
If you use the address transfer function to transfer your address to someone else, you can also transfer your password as a set.
