I have version 3.0.3 and i have a password when i open my wallet and send.
Did you download Electrum from anywhere else other than electrum.org? Like a github link?
Did you receive a popup telling you to update your Electrum after trying to make a transaction?
Using v3.2.3 I saw the phishing popup yesterday from one of the rogue servers when i tried to do a tx. I'm sorry I forgot to screenshot, but it wasn't a github url. It was electrum
something.com. Probably github kicked the phishers out and they registered another more "innocuous looking" url... I just switched to a trusted known server and did the tx fine (despite another nag saying my Electrum was "vulnerable", download a new version from electrum.org yadda, yadda.).
I already upgraded to v3.3.3... Was just waiting for the Arch package update.
