Since the password was sent by FR's software, I'd hope that it would be correct. It would be kind of useless for FR to send out incorrect passwords when people want to confirm their passwords.
I don’t think FR sends out unsecured email password confirmations...
You can reset a password,
The real story here is that FR was even able to send you your password. That means they are storing everyone’s passwords in an unencrypted format. So, if anyone was able to hack their way in to admin-level access, they could probably download the passwords for every user, in plain text.
